TITLE

METHOD FOR CONTROLLING PARTICULAR LNSECT PESTS BY APPLYING

ANTHRANILAMIDE COMPOUNDS

BACKGROUND OF THE INVENTION This invention relates to a method of use for controlling invertebrate pests in both agronomic and nonagronomic environments of certain anthranilamides, their N-oxides, agriculturally suitable salts and compositions.

The control of invertebrate pests is extremely important in achieving high crop efficiency. Damage by invertebrate pests to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of invertebrate pests in forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds that are more effective, less costly, less toxic, environmentally safer or have different modes of action.

DETAILS OF THE INVENTION In the above recitations, the term "alkyl", used either alone or in compound words such as "alkylthio" or "haloalkyl" includes straight-chain or branched alkyl, such as, methyl, ethyl, 77-propyl, -propyl, or the different butyl, pentyl or hexyl isomers. "Alkenyl" includes straight-chain or branched alkenes such as 1-propenyl, 2-propenyl, and the different butenyl, pentenyl andhexenyl isomers. "Alkenyl" also includes polyenes such as 1,2-propadienyl and 2,4-hexadienyl "Alkynyl" includes straight-chain or branched alkynes such as

1 -propynyl, 2-propynyl and the different butynyl, pentynyl and hexynyl isomers. "Alkynyl" can also include moieties comprised of multiple triple bonds such as 2,5-hexadiynyl. "Alkoxy" includes, for example, methoxy, ethoxy, «-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers. "Alkoxyalkyl" denotes alkoxy substitution on alkyl. Examples of "alkoxyalkyl" include CH₃OCH₂, CH₃OCH₂CH₂, CH₃CH₂OCH₂, CH₃CH₂CH₂CH₂OCH₂ and CH CH₂OCH₂CH₂. "Alkylthio" includes branched or straight-chain alkylthio moieties such as methylthio, ethylthio, and the different propylthio, butylthio, pentylthio and hexylthio isomers. "Cycloalkyl" includes, for example, cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. The term "heterocyclic ring" or heterocyclic ring system" denotes rings or ring systems in which at least one ring atom is not carbon and comprises 1 to 4 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur, provided that each heterocyclic ring contains no more than 4 nitrogens, no more than 2 oxygens and no more than 2 sulfurs. The heterocyclic ring can be attached through any available carbon or nitrogen by replacement of hydrogen on said carbon or nitrogen. The term "aromatic ring system" denotes fully unsaturated carbocycles and heterocycles in which at least one ring of the polycyclic ring system is aromatic (where aromatic indicates that the Hύckel rule is satisfied for the ring system). The term "heteroaromatic ring" denotes fully aromatic rings in which at least one ^'ring atom is not carbon and comprises 1 to 4 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur, provided that each heterocyclic ring contains no more than 4 nitrogens, no more than 2 oxygens and no more than 2 sulfurs (where aromatic indicates that the Hύckel rule is satisfied). The heterocyclic ring can be attached through any available carbon or nitrogen by replacement of hydrogen on said carbon or nitrogen. The term "aromatic heterocyclic ring system" includes fully aromatic heterocycles and heterocycles in which at least one ring of a polycyclic ring system is aromatic (where aromatic indicates that the Hύckel rule is satisfied). The term "fused heterobicyclic ring system" includes a ring system comprised of two fused rings in which at least one ring atom is not carbon and can be aromatic or non aromatic, as defined above. The term "halogen", either alone or in compound words such as "haloalkyl", includes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as "haloalkyl", said alkyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of "haloalkyl" include F₃C, C1CH₂, CF3CH2 and CF₃CC1₂. The terms "haloalkenyl", "haloalkynyl", "haloalkoxy", and the like, are defined analogously to the term "haloalkyl". Examples of "haloalkenyl" include (C1)₂C=CHCH₂ and CF₃CH₂CH=CHCH₂. Examples of "haloalkynyl" include HC≡CCHCl, CF₃C≡C, CC1₃C=C and FCH₂CsCCH₂. Examples of "haloalkoxy" include CF₃0, CCl₃CH₂O, HCF₂CH₂CH₂O and CF₃CH₂O. The total number of carbon atoms in a substituent group is indicated by the "Cj-C_j" prefix where i and j are numbers from 1 to 8. For example, C -C4 alkylsulfonyl designates methylsulfonyl through butylsulfonyl; C₂ alkoxyalkyl designates CH₃OCH2; C₃ alkoxyalkyl designates, for example, CH₃CH(OCH₃), CH₃OCH₂CH₂ or CH₃CH₂OCH₂; and C₄ alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH₃CH CH₂OCH₂ and CH CH OCH CH₂. In the above recitations, when a compound of Formula I comprises a heterocyclic ring, all substituents are attached to this ring through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

The term "optionally substituted with one to three substituents" indicates that one to three of the available positions on the group may be substituted. When a group contains a substituent which can be hydrogen, for example R⁶, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.

Compounds of Formula I can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the compounds of Formula I may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form. Similarly, compounds of Formula 10 can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer of a compound of Formula 10 may be more useful in preparing a specific stereoisomer of Formula I. Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the compounds of Formula 10 may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form. The salts of the compounds of Formula I include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. As noted above, R⁷ is (among others) a phenyl, a benzyl, a 5- or 6-membered heteroaromatic ring, a naphthyl ring system or an aromatic 8-, 9- or 10-membered fused heterobicyclic ring system, each ring or ring system optionally substituted with one to three substituents independently selected from R⁹. The term "optionally substituted" in connection with these R⁷ groups refers to groups which are unsubstituted or have at least one non-hydrogen substituent that does not extinguish the invertebrate pest control activity possessed by the unsubstituted analog. Note also that J-l through J-4 below denote 5- or 6-membered heteroaromatic rings. An example of a phenyl ring optionally substituted with 1 to 3 R⁹ is the ring illustrated as J-5 in Exhibit 1, wherein r is an integer from 0 to 3. An example of a benzyl ring optionally substituted with 1 to 3 R⁹ is the ring illustrated as J-6 in Exhibit 1 , wherein r is an integer from 0 to 3. An example of a naphthyl ring system optionally substituted with 1 to 3 R⁹ is illustrated as J-59 in Exhibit 1, wherein r is an integer from 0 to 3. Examples of a 5- or 6-membered heteroaromatic ring optionally substituted with 1 to 3 R⁹ include the rings J-7 through J-58 illustrated in Exhibit 1 wherein r is an integer from 0 to 3. Note that J-7 through J-26 are examples of J-l, J-27 through J-41 are examples of J-2, and J-46 through J-58 are examples of J-3 and J-4. The nitrogen atoms that require substitution to fill then valence are substituted with H or R⁹. Note that some J groups can only be substituted with less than 3 R⁹ groups (e.g. J-l 9, J-20, J-23 through J-26 and J-37 through J-40 can only be substituted with one R⁹). Examples of aromatic 8-, 9- or 10-membered fused heterobicyclic ring systems optionally substituted with 1 to 3 R⁹ include J-60 through J-90 illustrated in Exhibit 1 wherein r is an integer from 0 to 3. Although R⁹ groups are shown in the structures J-5 through J-90, it is noted that they do not need to be present since they are optional substituents. Note that when the attachment point between (R⁹)_r and the J group is illustrated as floating, (R⁹)_r can be attached to any available carbon atom of the J group. Note that when the attachment point on the J group is illustrated as floating, the J group can be attached to the remainder of Formula I through any available carbon of the J group by replacement of a hydrogen atom.

One or more of the following methods and variations as described in Schemes 1-22 can be used to prepare the compounds of Formula I. The definitions of A, B and R¹ through R⁹ in the compounds of Formulae 2-40 below are as defined above in the Summary of the Invention unless indicated otherwise. Compounds of Formulae Ia-d, 2a-d, 3a, 4a- , 5a-b, 17a-c, 18a and 32a-b are various subsets of the compounds of Formula I, 2, 3, 4, 5, 17, 18 and 32. In the schemes, Het is the moiety shown below:

Hetis

A typical method for preparation of a compound of Formula la is described in Scheme 1.

Scheme 1

la (A is O) lb (A is S) The method of Scheme 1 involves coupling of an amine of Formula 2 with an acid chloride of Formula 3 in the presence of an acid scavenger to provide the compound of Formula la. Typical acid scavengers include amine bases such as triethylamine, N,N-diisopiOpylethylamine and pyridine; other scavengers include hydroxides such as sodium and potassium hydroxide and carbonates such as sodium carbonate and potassium carbonate. In certain instances it is useful to use polymer-supported acid scavengers such as polymer-bound NN-diisopropylethylamine and polymer-bound 4-(dime1hylamino)pyridine. The coupling can be run in a suitable inert solvent such as tetrahydrofuran, dioxane, diethylether or dichloromethane to afford the anilide of Formula la. A thioamide of Formula lb can be obtained in a subsequent step from the corresponding amide of Formula la by treatment with one of a variety of standard thio transfer reagents including phosphorus pentasulfide and Lawesson's reagent (2,4-bis(4- methoxyphenyl)- 1 , 3 -dithia-2,4-diphosphetane-2,4-disulfιde) .

As shown in Scheme 2, an alternate procedure for the preparation of compounds of Formula la involves coupling of an amine of Formula 2 with an acid of Formula 4 in the presence of a dehydrating agent such as cticyclohexylcarbodiimide (DCC), l,r-carbonyl- diimidazole, bis(2-oxo-3-oxazohdinyl)phosphinic chloride or benzotriazol-l~yloxy-tris- (dimethylamino)phosphonium hexafluoroρhosρhate.

Scheme 2

Polymer-supported reagents are again useful here, such as polymer-bound cyclohexylcarbodiimide. The coupling can be run in a suitable inert solvent such as dichloromethane or N,N-dimethylformamide. The synthetic methods of Schemes 1 and 2 are just representative examples of a wide variety of coupling methods useful for the preparation of Formula I compounds; the synthetic literature is extensive for this type of coupling reaction.

One skilled in the art will also realize that acid chlorides of Formula 3 may be prepared from acids of Formula 4 by numerous well-known methods. For example, acid chlorides of Formula 3 are readily made from carboxylic acids of Formula 4 by reacting the carboxylic acid 4 with thionyl chloride or oxalyl chloride in an inert solvent such as toluene or dichloromethane in the presence of a catalytic amount of N,N-dimethylformamide.

As shown in Scheme 3, amines of Formula 2a are typically available from the corresponding 2-nitrobenzamides of Formula 5 via catalytic hydrogenation of the nitro group.

Scheme 3

aldehyde reductive alkylation

2a 2b (R¹ is other than H) Typical procedures involve reduction with hydrogen in the presence of a metal catalyst such as palladium on carbon or platinum oxide and in hydroxylic solvents such as ethanol and isopropanol. Amines of Formula 2a can also be prepared by reduction with zinc in acetic acid. These procedures are well documented in the chemical literature. ¹ substituents such as C -Cg alkyl can be introduced at this stage through well known methodologies including either direct alkylation or through the generally preferred method of reductive alkylation of the amine. As is further shown in Scheme 3, a commonly employed procedure is to combine the amine 2a with an aldehyde in the presence of a reducing agent such as sodium cyanoborohydride to produce the Formula 2b compounds where R¹ is C -Cg alkyl.

Scheme 4 shows that compounds of Formula Ic can be alkylated or acylated with a suitable alkylating or acylating agent such as an alkyl halide, alkyl chloroformate or acyl chloride in the presence of a base such as sodium hydride or n-butyllithium in an inert solvent such as tetrahydrofuran or N,N-dimethylformamide to afford anilides of Formula Id wherein R¹ is other than hydrogen.

Scheme 4

alkylating or acylating agent base, solvent

Ic Id (R¹ is other than H)

The intermediate amides of Formula 5a are readily prepared from commercially available 2-nitrobenzoic acids. Typical methods for amide formation can be used. As shown in Scheme 5, these methods include direct dehydrative coupling of acids of Formula 6 with amines of Formula 7 using for example DCC, and conversion of the acids to activated forms such as the acid chlorides or anhydrides and subsequent coupling with amines to form amides of Formula 5a.

Scheme 5 amide formation

5a (B is O) 5b (B is S) Alkyl chloro formates, such as ethyl chloroformate or isopropyl chloroformate, are especially useful reagents for this type of reaction involving activation of the acid. The chemical literature is extensive regarding methods for amide formation. Amides of Formula 5a are readily converted to thioamides of Formula 5b by using commercially available thio transfer reagents such as phosphorus pentasulfide and Lawesson's reagent.

Intermediate anthranilic amides of Formula 2c or 2d may also be prepared from isatoic anhydrides of Formula 8 or 9, respectively, as shown in Scheme 6.

Scheme 6

2d (R¹ is other than H) Typical procedures involve combination of equimolar amounts of the amine 7 with the isatoic anhydride in polar aprotic solvents such as pyridine and N,N-dimethylformamide at temperatures ranging from room temperature to 100 °C. * substituents such as alkyl and substituted alkyl may be introduced by the base-catalyzed alkylation of isatoic anhydride 8 with known alkylating reagents ^Lg (wherein Lg is a nucleophilic displaceable leaving group such as halide, alkyl or aryl sulfonates or alkyl sulfates) to provide the alkyl substituted intermediate 9. Isatoic anhydrides of Formula 8 may be made by methods described in Coppola, Synthesis 1980, 505-36.

As shown in Scheme 7, an alternate procedure for the preparation of specific compounds of Formula ic involves reaction of an amine 7 with a benzoxazinone of Formula 10. Scheme 7

The reaction of Scheme 7 can be run neat or in a variety of suitable solvents including tetrahydrofuran, diethyl ether, pyridine, dichloromethane or chloroform with optimum temperatures ranging from room temperature to the reflux temperature of the solvent. The general reaction of benzoxazinones with amines to produce anthranilamides is well documented in the chemical literature. For a review of benzoxazinone chemistry see Jakobsen et al, Biorganic and Medicinal Chemistry 2000, 8, 2095-2103 and references cited therein. See also Coppola, J. Heterocyclic Chemistry 1999, 36, 563-588.

Benzoxazinones of Formula 10 can be prepared by a variety of procedures. Two procedures that are especially useful are detailed in Schemes 8-9. In Scheme 8, a benzoxazinone of Formula 10 is prepared directly via coupling of a pyrazolecarboxylic acid of Formula 4a with an anthranilic acid of Formula 11.

Scheme 8

3. tertiary ainine

This involves sequential addition of methanesulfonyl chloride in the presence of a tertiary amine such as triethylamine or pyridine to a pyrazolecarboxylic acid of Formula 4a, followed by the addition of an anthranilic acid of Formula 11, followed by a second addition of tertiary amine and methanesulfonyl chloride. This procedure generally affords good yields of the benzoxazinone and is illustrated with greater detail in Examples 6 and 8. Scheme 9 depicts an alternate preparation for benzoxazinones of Formula 10 involving coupling of a pyrazole acid chloride of Formula 3a with an isatoic anhydride of Formula 8 to provide the Formula 10 benzoxazinone directly.

3a

Solvents such as pyridine or pyridine/acetonitrile are suitable for this reaction. The acid chlorides of Formula 3a are available from the corresponding acids of Formula 4a by a variety of synthetic methods such as chlorination with thionyl chloride or oxalyl chloride.

Isatoic anhydrides of Formula 8 can be prepared from isatins of Formula 13 as outlined in Scheme 10.

Scheme 10

Isatins of Formula 13 are obtained from aniline derivatives of Formula 12 using methods known in the literature. Oxidation of isatin 13 with hydrogen peroxide generally affords good yields of the corresponding isatoic anhydride 8 (Angew. Chem. Int. Ed. Engl. 1980, 19, 222-223). Isatoic anhydrides are also available from the anthranilic acids 11 via many known procedures involving reaction of 11 with phosgene or a phosgene equivalent.

The syntheses of representative acids of Formula 4 are depicted in Schemes 11-16. Syntheses of pyrazoles of Formula 4a are shown in Scheme 11.

Scheme 11

14

Lg is a leaving group 16 4a The synthesis of compounds of Formula 4a in Scheme 11 involves as the key step introduction of the R⁷ substituent via alkylation or arylation of the pyrazole of Formula 14 with compounds of Formula 15 (wherein Lg is a leaving group as defined above). Oxidation of the methyl group affords the pyrazole carboxylic acid. Some of the more preferred R^ groups include haloalkyl.

Synthesis of pyrazoles of Formula 4a is also shown in Scheme 12.

Scheme 12

These acids may be prepared via metallation and carboxylation of compounds of Formula 18 as the key step. The R⁷ group is introduced in a manner similar to that of Scheme 11, i.e. via alkylation or arylation with a compound of Formula 15. Representative R⁶ groups include e.g. cyano, haloalkyl and halogen.

This procedure is particularly useful for preparing l-(2-pyridinyl)pyrazolecarboxylic acids of Formula 4b as shown in Scheme 13.

Scheme 13

18a 4b

Reaction of a pyrazole of Formula 17 with a 2,3-dihalopyridine of Formula 15a affords good yields of the 1-pyridylpyrazole of Formula 18a with good specificity for the desired regiochemistry. Metallation of 18a with lithium diisopropylamide (LDA) followed by quenching of the Hthium salt with carbon dioxide affords the l-(2-pyridinyl)pyrazole- carboxylic acid of Formula 4b. Additional details for these procedures are provided in Examples 1, 3, 6, 8 and 10.

The synthesis of pyrazoles of Formula 4c is described in Scheme 14. Scheme 14

Scheme 14 involves reaction of an optionally substituted phenyl hydrazine of Formula 19 with a ketopyruvate of Formula 20 to yield pyrazole esters of Formula 21. Hydrolysis of the esters affords the pyrazole acids of Formula 4c. This procedure is particularly useful for the preparation of compounds in which R⁷ is optionally substituted phenyl and R⁶ is haloalkyl. An alternate synthesis of pyrazole acids of Formula 4c is described in Scheme 15.

Scheme 15

The method of Scheme 15 involves 3+2 cycloaddition of an appropriately substituted iminohalide 22 with either substituted propiolates of Formula 23 or acrylates of Formula 25. Cycloaddition with an aery late requires additional oxidation of the intermediate pyrazoline to the pyrazole. Hydrolysis of the esters affords the pyrazole acids of Formula 4c. Preferred iminohalides for this reaction include the trifluoromethyl iminochloride of Formula 26 and the iminodibromide of Formula 27. Compounds such as 26 are known (J. Heterocycl. Chem. 1985, 22(2), 565-8). Compounds such as 27 are available by known methods (Tetrahedron Letters 1999, 40, 2605). These¹ procedures are particularly useful for the preparation of compounds where R⁷ is optionally substituted phenyl and ⁶ is haloalkyl or bromo.

The starting pyrazoles of Formula 17 are known compounds or can be prepared according to known methods. The pyrazole of Formula 17a (the compound of Formula 17 wherein R⁶ is CF₃ and R⁸ is H) can be prepared by literature procedures (J. Fluorine Chem. 1991, 53(1), 61-70). The pyrazoles of Formula 17c (compounds of Formula 17 wherein R⁶ is Cl or Br and R⁸ is H) can also be prepared by literature procedures (Chem. Ber. 1966, 99(10), 3350-7). A useful alternative method for the preparation of compound 17c is depicted in Scheme 16.

In the method of Scheme 16, metallation of the sulfamoyl pyrazole of Formula 28 with n-butyllithium followed by direct halogenation of the anion with either hexachloroethane (for R⁶ being Cl) or 1,2-dibromotetrachloroethane (for R⁶ being Br) affords the halogenated derivatives of Formula 29. Removal of the sulfamoyl group with trifluoro acetic acid (TFA) at room temperature proceeds cleanly and in good yield to afford the pyrazoles of Formula 17c. One skilled in the art will recognize that Formula 17c is a tautomer of Formula 17b. Further experimental details for these procedures are described in Examples 8 and 10. Pyrazolecarboxylic acids of Formula 4d wherein R⁶ is H, C2-Cg alkyl or C -C₆ haloalkyl can be prepared by the method outlined in Scheme 17. Scheme 17

Reaction of a compound of Formula 30 wherein R¹³ is C -C₄ alkyl with a suitable base in a suitable organic solvent affords the cyclized product of Formula 31 after neutralization with an acid such as acetic acid. The suitable base can be, for example but not limitation, sodium hydride, potassium t-butoxide, dimsyl sodium (CH₃S(O)CH₂ ^~ Na⁺), alkali metal (such as lithium, sodium or potassium) carbonates or hydroxides, tetraalkyl (such as methyl, ethyl or butyl)ammonium fluorides or hydroxides, or 2-te/ -butylimmo-2-die ylanhho-l,3-dimethyl- perhydiO-l,3,2-diazaphosphonine. The suitable organic solvent can be, for example but not limitation, acetone, acetonitrile, tetrahydrofuran, dichloromethane, dimethylsulfoxide, or N,N-dimethylformamide. The cyclization reaction is usually conducted in a temperature range from about 0 to 120 °C. The effects of solvent, base, temperature and addition time are all interdependent, and choice of reaction conditions is important to minimize the formation of byproducts. A preferred base is tefrabutylarr ionium fluoride. Dehydration of the compound of Formula 31 to give the compound of Formula 32, followed by converting the carboxylic ester function to carboxylic acid, affords the compound of Formula 4d. The dehydration is effected by treatment with a catalytic amount of a suitable acid. This catalytic acid can be, for example but not limitation, sulfuric acid. The reaction is generally conducted using an organic solvent. As one skilled in the art will realize, dehydration reactions may be conducted in a wide variety of solvents in a temperature range generally between about 0 and 200 °C, more preferably between about 0 and 100 °C. For the dehydration in the method of Scheme 17, a solvent comprising acetic acid and temperatures of about 65 °C are preferred. Carboxylic ester compounds can be converted to carboxylic acid compounds by numerous methods cluding nucleophilic cleavage under anhydrous conditions or hydrolytic methods involving the use of either acids or bases (see T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2nd ed., John Wiley & Sons, Inc., New York, 1991, pp. 224-269 for a review of methods). For the method of Scheme 17, base-catalyzed hydrolytic methods are preferred. Suitable bases include alkali metal (such as lithium, sodium or potassium) hydroxides. For example, the ester can be dissolved in a mixture of water and an alcohol such as ethanol. Upon treatment with sodium hydroxide or potassium hydroxide, the ester is saponified to provide the sodium or potassium salt of the carboxylic acid. Acidification with a strong acid, such as hydrochloric acid or sulfuric acid, yields the carboxylic acid of Formula 4d. The carboxylic acid can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation.

Compounds of Formula 30 can be prepared by the method outlined in Scheme 18.

Treatment of a hydrazine compound of Formula 33 with a ketone of Formula 34 in a solvent such as water, methanol or acetic acid gives the hydrazone of Formula 35. One skilled in the art will recognize that this reaction may require catalysis by an optional acid and may also require elevated temperatures depending on the molecular substitution pattern of the hydrazone of Formula 35. Reaction of the hydrazone of Formula 35 with the compound of Formula 36 in a suitable organic solvent such as, for example but not limitation, dichloromethane or tetrahydrofuran in the presence of an acid scavenger such as triethylamine provides the compound of Formula 30. The reaction is usually conducted at a temperature between about 0 and 100 °C. Further experimental details for the method of Scheme 18 are illustrated in Example 17. Hydrazine compounds of Formula 33 can be prepared by standard methods, such as by contacting the corresponding halo compound of Formula 15a with hydrazine.

Pyrazolecarboxylic acids of Formula 4d wherein R⁶ is halogen can be prepared by the method outlined in Scheme 19. Scheme 19

37 32 wherein R¹³ is C2-C4 alkyl.

Oxidization of the compound of Formula 37 optionally in the presence of acid to give the compound of Formula 32 followed by conversion of the carboxylic ester function to the carboxylic acid provides the compound of Formula 4d. The oxidizing agent can be hydrogen peroxide, organic peroxides, potassium persulfate, sodium persulfate, ammonium persulfate, potassium monopersulfate (e.g., Oxone®) or potassium permanganate. To obtain complete conversion, at least one equivalent of oxidizing agent versus the compound of Formula 37 should be used, preferably between about one to two equivalents. This oxidation is typically carried out in the presence of a solvent. The solvent can be an ether, such as tetrahydrofuran, 7-dioxane and the like, an organic ester, such as ethyl acetate, dimethyl carbonate and the like, or a polar aprotic organic such as N,N-dimethylformamide, acetonitrile and the like. Acids suitable for use in the oxidation step include inorganic acids, such as sulfuric acid, phosphoric acid and the like, and organic acids, such as acetic acid, benzoic acid and the like. The acid, when used, should be used in greater than 0.1 equivalents versus the compound of Formula 37. To obtain complete conversion, one to five equivalents of acid can be used. The preferred oxidant is potassium persulfate and the oxidation is preferably carried out in the presence of sulfuric acid. The reaction can be carried out by mixing the compound of Formula 37 in the desired solvent and, if used, the acid. The oxidant can then be added at a conyenient rate. The reaction temperature is typically varied from as low as about 0 °C up to the boiling point of the solvent in order to obtain a reasonable reaction time to complete the reaction, preferably less than 8 hours. The desired product, a compound of Formula 32 can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation. Methods suitable for converting the ester of Formula 32 to the carboxylic acid of Formula 4d are already described for Scheme 17. Further experimental details for the method of Scheme 19 are illustrated in Examples 12 and 13.

Compounds of Formula 37 can be prepared from corcesponding compounds of Formula 38 as shown in Scheme 20. Scheme 20

38 37 wherein R¹³ is Cj-C* alkyl and R⁶ is halogen.

Treatment of a compound of Formula 38 with a halogenating reagent, usually in the presence of a solvent, affords the corresponding halo compound of Formula 37. Halogenating reagents that can be used include phosphorus oxyhalides, phosphorus trihalides, phosphorus pentahalides, thionyl chloride, dihalotrialkylphosphoranes, dihalodiphenylphosphoranes, oxalyl chloride and phosgene. Preferred are phosphorus oxyhalides and phosphorus pentahalides. To obtain complete conversion, at least 0.33 equivalents of phosphorus oxyhalide versus the compound of Formula 38 (i.e. the mole reatio of phosphorus oxyhalide to Formula 18 is at least 0.33) should be used, preferably between about 0.33 and 1.2 equivalents. To obtain complete conversion, at least 0.20 equivalents of phosphorus pentahalide versus the compound of Formula 38 should be used, preferably between about 0.20 and 1.0 equivalents. Compounds of Formula 38 wherein R¹³ is C -C4 alkyl are preferred for this reaction. Typical solvents for this halogenation include halogenated alkanes, such as dic oromethane, chloroform, chlorobutane and the like, aromatic solvents, such as benzene, xylene, chlorobenzene and the like, ethers, such as tetrahydrofuran, p-άioxaae, diethyl ether, and the like, and polar aprotic solvents such as acetonitrile, N,N-drmethylformamide, and the like. Optionally, an organic base, such as triethylamine, pyridine, N,N-dimethylaniline or the like, can be added. Addition of a catalyst, such as N,N-dimethylformamide, is also an option. Preferred is the process in which the solvent is acetonitrile and a base is absent. Typically, neither a base nor a catalyst is required when acetonitrile solvent is used. The preferred process is conducted by mixing the compound of Formula 38 in acetonitrile. The halogenating reagent is then added over a convenient time, and the mixture is then held at the desired temperature until the reaction is complete. The reaction temperature is typically between 20 °C and the boiling point of acetonitrile, and the reaction time is typically less than 2 hours. The reaction mass is then neutralized with an inorganic base, such as sodium bicarbonate, sodium hydroxide and the like, or an organic base, such as sodium acetate. The desired product, a compound of Formula 37, can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation.

Alternatively, compounds of Formula 37 wherein R⁶ is halogen can be prepared by treating the corresponding compounds of Formula 37 wherein R⁶ is a. different halogen (e.g., Cl for making Formula 37 wherein R³ is Br) or a sulfonate group such as jo-toluenesulfonate, benzenesulfonate and methanesulfonate with the appropriate hydrogen halide. By this method the R⁶ halogen or sulfonate substituent on the Formula 37 starting compound is replaced with, for example, Br or Cl from hydrogen bromide or hydrogen chloride, respectively. The reaction is conducted in a suitable solvent such as dibromomethane, dichloromethane or acetonitrile. The reaction can be conducted at or near atmospheric pressure or above atmospheric pressure in a pressure vessel. When R⁶ in the starting compound of Formula 37 is a halogen such as Cl, the reaction is preferably conducted in such a way that the hydrogen halide generated from the reaction is removed by sparging or other suitable means. The reaction can be conducted between about 0 and 100 °C, most conveniently near ambient temperature (e.g., about 10 to 40 °C), and more preferably between about 20 and 30 °C. Addition of a Lewis acid catalyst (such as aluminum tribromide for preparing Formula 37 wherein R⁶ is Br) can facilitate the reaction. The product of Formula 37 is isolated by the usual methods known to those skilled in the art, including extraction, distillation and crystallization. Further details for this process are illustrated in Example 14.

Starting compounds of Formula 37 wherein R⁶ is Cl or Br can be prepared from corresponding compounds of Formula 38 as already described. Starting compounds of Formula 37 wherein R⁶ is a sulfonate group can likewise be prepared from corresponding compounds of Formula 38 by standard methods such as treatment with a sulfonyl chloride (e.g., jD-toluenesulfonyl chloride) and base such as a tertiary amine (e.g., tήethylamine) in a suitable solvent such as dichloromethane; further details for this process are illustrated in Example 15.

Pyrazolecarboxylic acids of Formula 4d wherein R⁶ is C -C4 alkoxy or C -C4 haloalkoxy can also be prepared by the method outlined in Scheme 21.

Scheme 21

38 32a 32b wherein R¹³ is C -C₄ alkyl, andX is a leaving group.

In this method, instead of being halogenated as shown in Scheme 20, the compound of Formula 38 is oxidized to the compound of Formula 32a. The reaction conditions for this oxidation are as already described for the conversion of the compound of Formula 37 to the compound of Formula 32 in Scheme 19.

The compound of Formula 32a is then alkylated to form the compound of Formula 32b by contact with an alkylating agent CF CH₂X (39) in the presence of a base. In the alkylating agent 39, X is a nucleophilic reaction leaving group such as halogen (e.g., Br, I), OS(O)₂CH₃ (methanesulfonate), OS(O)₂CF₃, OS(O)₂Ph- -CH₃ (p-toluenesulfonate), and the like; methanesulfonate works well. The reaction is conducted in the presence of at least one equivalent of a base. Suitable bases include inorganic bases, such as alkali metal (such as lithium, sodium or potassium) carbonates and hydroxides, and organic bases, such as triethylamine, diisopropylethylamine and l,8-diazabicyclo[5.4.0]undec-7-ene. The reaction is generally conducted in a solvent, which can comprise alcohols, such as methanol and ethanol, halogenated alkanes, such as dichloromethane, aromatic solvents, such as benzene, toluene and chlorobenzene, ethers, such as tetrahydrof ran, and polar aprotic solvents, such as acetonitrile, such as such as acetonitrile, N,N-dimethylformamide, and the like. Alcohols and polar aprotic solvents are preferred for use with inorganic bases. Potassium carbonate as base and acetonitrile as solvent are preferred. The reaction is generally conducted between about 0 and 150 °C, with most typically between ambient temperature and 100 °C. The product of Formula 32b can be isolated by conventional techniques such as extraction. The ester of Formula 32b can then be converted to the carboxylic acid of Formula 4d by the methods already described for the conversion of Formula 32 to Formula 4d in Scheme 17. Further experimental details for the method of Scheme 21 are illustrated in Example 16. Compounds of Formula 38 can be prepared from compounds of Formula 33 as outlined in Scheme 22.

Formula 40 (a fumarate ester or maleate ester or a mixture thereof may be used) in the presence of a base and a solvent. The base is typically a metal alkoxide salt, such as sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, potassium tert-butoxide, lithium tert-butoxide, and the like. Greater than 0.5 equivalents of base versus the compound of Formula 33 should be used, preferably between 0.9 and 1.3 equivalents. Greater than 1.0 equivalents of the compound of Formula 40 should be used, preferably between 1.0 to 1.3 equivalents. Polar protic and polar aprotic organic solvents can be used, such as alcohols, acetonitrile, tefrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide and the like. Preferred solvents are alcohols such as methanol and ethanol. It is especially preferred that the alcohol be the same as that making up the fumarate or maleate ester and the alkoxide base. The reaction is typically conducted by mixing the compound of Formula 33 and the base in the solvent. The mixture can be heated or cooled to a desired temperature and the compound of Formula 40 added over a period of time. Typically reaction temperatures are between 0 °C and the boiling point of the solvent used. The reaction may be conducted under greater than atmospheric pressure in order to increase the boiling point of the solvent. Temperatures between about 30 and 90 °C are generally preferred. The addition time can be as quick as heat transfer allows. Typical addition times are between 1 minute and 2 hours. Optimum reaction temperature and addition time vary depending upon the identities of the compounds of Formula 33 and Formula 40. After addition, the reaction mixture can be held for a time at the reaction temperature. Depending upon the reaction temperature, the required hold time may be from 0 to 2 hours. Typical hold times are 10 to 60 minutes. The reaction mass then can be acidified by adding an organic acid, such as acetic acid and the like, or an inorganic acid, such as hydrochloric acid, sulfuric acid and the like. Depending on the reaction conditions and the means of isolation, the -CO₂R¹³ function on the compound of Formula 38 may be hydrolyzed to -CO₂H; for example, the presence of water in the reaction mixture can promote such hydrolysis. If the carboxylic acid (-CO₂H) is formed, it can be converted back to -C0₂R¹³ wherein R¹³ is C1-C alkyl using esterification methods well-known in the art. The desired product, a compound of Formula 38, can be isolated by methods known to those skilled in the art, such as crystallization, extraction or distillation.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991).

A 2-L four-necked flask equipped with a mechanical stirrer, thermometer, addition funnel, reflux condenser, and nitrogen inlet was charged with absolute ethanol (250 mL) and an ethanolic solution of sodium ethoxide (21%, 190 mL, 0.504 mol). The mixture was heated to reflux at about 83 °C. It was then treated with 3-chloro-2(lH)-pyridinone hydrazone (68.0 g, 0.474 mol). The mixture was re-heated to reflux over a period of 5 minutes. The yellow slurry was then treated dropwise with diethyl maleate (88.0 mL, 0.544 mol) over a period of 5 minutes. The reflux rate increased markedly during the addition. By the end of the addition all of the starting material had dissolved. The resulting orange-red solution was held at reflux for 10 minutes. After being cooled to 65 °C, the reaction mixture was treated with glacial acetic acid (50.0 mL, 0.873 mol). A precipitate formed. The mixture was diluted with water (650 mL), causing the precipitate to dissolve. The orange solution was cooled in an ice bath. Product began to precipitate at 28 °C. The slurry was held at about 2 °C for 2 hours. The product was isolated via filtration, washed with aqueous ethanol (40%, 3 x 50 mL), and then air-dried on the filter for about 1 hour.

Upon adding the phosphorus oxychloride, the mixture self-heated from 22 to 25 °C and a precipitate formed. The light- yellow slurry was heated to reflux at 83 °C over a period of 35 minutes, whereupon the precipitate dissolved. The resulting orange solution was held at reflux for 45 minutes, whereupon it had become black-green. The reflux condenser was replaced with a distillation head, and 650 mL of solvent was removed by distillation.

(i.e. product of Example 12, Step A) (27 g, 100 mmol) stirred in dry acetonitrile (200 mL) was added sulfuric acid (20 g, 200 mmol) in one portion. The reaction mixture thinned to form a pale green, nearly clear solution before thickening again to form a pale yellow suspension. Potassium persulfate (33 g, 120 mmol) was added in one portion, and then the reaction mixture was heated at gentle reflux for 3.5 hours. After cooling using an ice bath, a precipitate of white solid was removed by filtration and discarded. The filtrate was diluted with water (400 mL) and then extracted three times with ethyl ether (700 mL total). Concentration of the combined ether extracts to a reduced volume (75 mL) caused precipitation of an off-white sohd (3.75 g), which was collected by filtration. The ether mother liquor was further concentrated to yield a second crop of an off-white precipitate (4.2 g), which was also collected by filtration. An off-white sohd also precipitated from the aqueous phase; this sohd (4.5 g) was collected by filtration to provide a combined total of 12.45 g of the title compound.

Formulation/Utility

Compounds of this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifϊable concentrates), suspensions, emulsions (including micro emulsions and or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. Spray able formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges that add up to 100 percent by weight.

Weight Percent

Active Ingredient Diluent Surfactant

Water-Dispersible and Water-soluble 5-90 0-94 1-15 Granules, Tablets and Powders.

Suspensions, Emulsions, Solutions 5-50 40-95 0-15 (includbig Emulsifiable Concentrates)

Dusts 1-25 70-99 0-5

Granules and Pellets 0.01-99 5-99.99 0-15

High Strength Compositions 90-99 0-10 0-2

Typical solid diluents are described in Watkins, et al, Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon 's Detergents and Emulsiβers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.

Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanόne, isophorone and 4-hydroxy-4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol.

Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-48, Periγ's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and PCT Publication WO 91/13546. Pellets can be prepared as described in U.S. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. 4,144,050, U.S. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. 5,180,587, U.S. 5,232,701 and U.S. 5,208,030. Films can be prepared as taught in GB 2,095,558 and U.S. 3,299,566.

In certain instances, combinations with other invertebrate pest control compounds or agents having a similar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Thus, compositions of the present invention can further comprise an biologically effective amount of at least one additional invertebrate pest control compounds or agents having a similar spectrum of control but a different mode of action. Contacting a plant genetically modified to express a plant protection compound (e.g., protein) or the locus of the plant with a biologically effective amount of a compound of invention can also provide a broader spectrum of plant protection and be advantageous for resistance management.

Invertebrate pests are controlled and protection of agronomic, horticultural and specialty crops, animal and human health is achieved by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of foliar- and soil-inhabiting invertebrates and protection of agronomic and/or nonagronomic crops, comprising contacting the invertebrates or their environment with a biologically effective amount of one or more of the compounds of the invention, or with a composition comprising at least one such compound or a composition comprising at least one such compound and an effective amount of at least one additional biologically active compound or agent. A preferred method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention can be applied to the plant foliage or the soil. Compounds of this invention are effective in delivery through plant uptake by contacting the plant with a composition comprising a compound of this invention applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box treatment or a dip of transplants. Other methods of contact include application of a compound or a composition of the invention by direct and residual sprays, aerial sprays, seed coats, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others.

The compounds of this invention can be incorporated into baits that are consumed by the invertebrates or within devices such as traps and the like. Granules or baits comprising between 0.01-5% active ingredient, 0.05-10% moisture retaining agent(s) and 40-99% vegetable flour are effective in controlling soil insects at very low application rates, particularly at doses of active ingredient that are lethal by ingestion rather than by direct contact. The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl butpxide often enhance compound efficacy.

The rate of application required for effective control (i.e. "biologically effective amount") will depend on such factors as the species of invertebrate to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, apphcation rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.0001 kg hectare may be sufficient or as much as 8 kg/hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. One skilled in the art can easily determine the biologically effective amount necessary for the desired level of invertebrate pest control. The following Tests in the Biological Examples of the Invention demonstrate the efficacy of methods of the invention for protecting plants from specific arthropod pests. "Control efficacy" represents inhibition of arthropod development (including mortality) that causes significantly reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Table A for compound descriptions.

BIOLOGICAL EXAMPLES OF THE INVENTION TEST A

For evalua ing control of fall armyworm (Spodoptera frugiperda) the test unit consisted of a small open container with a 4-5-day-old corn (maize) plant inside. This was pre-infested with 10-15 1 -day-old larvae on a piece of insect diet by use of a core sampler to remove a plug from a sheet of hardened insect diet having many larvae growing on it and transfer the plug containing larvae and diet to the test unit. The larvae moved onto the test plant as the diet plug dried out.

Test compounds were formulated using a solution containing 10% acetone, 90% water and 300 ppm X-77® Spreader Lo-Foam Formula non-ionic surfactant containing alkylarylpolyoxyethylene, free fatty acids, glycols and isopropanol (Loveland Industries, Inc.), unless otherwise indicated. The formulated compounds were applied in 1 mL of Kquid through a SUJ2 atomizer nozzle with 1/8 JJ custom body (Spraying Systems Co.) positioned 1.27 cm (0.5 inches) above the top of each test unit. All experimental compounds in this screen were sprayed at 50 ppm and replicated three times. After spraying of the formulated test compound, each test unit was allowed to dry for 1 hour and then a black, screened cap was placed on top. The test units were held for 6 days in a growth chamber at 25 °C and 70% relative humidity. Plant feeding damage was then visually assessed.

Of the compounds tested, the following provided excellent levels of plant protection (10% or less feeding damage): 5, 11, 18, 19, 24, 28, 30, 32, 33, 34, 37, 38, 39, 40, 45, 46, 47, 48, 56, 57, 58, 59, 63, 64, 75, 76, 77, 78, 79, 84, 85, 86, 87, 91, 93, 94, 95, 96, 97, 98, 99, 108, 113, 114, 116, 115, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129,

TEST I For evaluating soil systemic control of tobacco budworm (Heliothis virescens), cotton plants were grown in sassafras soil in 15-cm pots in aluminum trays. When the plants reached square stage (bud formation on the plant) the plants were treated with the test compounds. Test compounds were formulated in 0.25 mL of acetone and then diluted with water to provide solutions of 10 ppm. Ten mL of the treatment solutions was added to the pots weekly for four weeks, with four replicates of each treatment rate. One day after the second, third and fourth treatments, 35-50 first instar Heliothis virescens larvae were brushed on each plant with paintbrushes and placed on the terminal area, squares, and bolls. Five days after the last infestation with larvae the plants were rated for damage. Of the compounds tested, the following provided excellent levels of plant protection at 10 ppm (10% or less feeding damage) with excellent protection of squares and bolls including no or minimal sepal demage: 214, 283 and 520. TEST J

Test H followed an alternative protocol for evaluating soil systemic control of tobacco budworm (Heliothis virescens). Cotton plants were grown in sassafras soil in 15-cm pots under greenhouse conditions. When the plants reached square stage (bud formation on the plant) the soil surface was treated with the test compounds. Test compounds were formulated in 0.25 mL of acetone and then diluted with water.

Ten mL of treatment solution containing 3 mg of compound was added to the soil surface of each pot. The plants were watered the next day and each day following as needed. At 1, 2 and 4 days after treatment, leaves were excised for evaluation. Two sets of leaves were selected from each plant: upper leaves at approximately second node from terminal and with area greater than 25 cm² and lower leaves at approximately third node from bottom and with area greater than 25 cm². The excised leaves were cut into 3 cm x 2 cm sections and placed into test trays made of high-impact styrene consisting of sixteen contiguous wells, each 6 cm wide, 4 cm long and 3 cm deep, with a clear plastic lid molded so that it locked into each well by friction. Sohdified agar was placed into the bottom of each well to maintain moisture for plant material. One second instar tobacco budworm was placed into each well with plant material; wells were sealed and held at 25 °C and provided with 16 hours of light per day

Of the compounds tested, the following compounds provided excellent levels of mortality (greater tiian 70% mortality) on upper leaves excised at 4 days after treatment at the test rate: 497, 530 and 543.

TEST K For evaluating soil systemic control of fall armyworm (Spodoptera frugiperdd), corn (maize) plants (Pioneer #3394) were grown in small pots for 5 days until they were at least 4 cm tall and the first leaf was unfurling. Test compounds were dissolved in 0.25 mL of acetone and diluted with water provide solutions of 1 , 10, 50 and 200 ppm. One mL of the test solution was applied by pipette to the surface of the soil in each pot, with eight plants for each compound/rate. The pots were covered and held at 25 °C with 16 hours of light per day. The plants were watered the next ay and each day following as needed. After 6 days, the plant matter above the first leaf was excised and cut into 3-cm lengths. Each test unit was a high-impact styrene tray (Supplier: Clearpack Company, 11610 Copenhagen Court, Franklin Park, IL 60131) consisting of sixteen contiguous wells each 6 cm wide, 4 cm long and 3 cm deep, with a clear plastic lid molded so that it locks into each well by friction. Solidified agar (2 to 4 mL) was placed onto the bottom of each well to maintain moisture in the wells during the test. Each 3-cm length of corn plant matter was placed into a tray such that the plant matter was contained within two wells. One second-instar fall armyworm (Spodoptera frugiperda) larva was placed in each well, the tray was covered and then the test units were held at at 25 °C with 16 hours of light per day. Mortality was observed after four days.

Of the compounds tested, the following provided excellent levels of mortality, with LC₉₀ values of 10 ppm or less: 200, 202, 313, 494, 497, 500, 513, 515, 516, 518, 520, 531, 533, 535, 538, 542, 543 and 544.

TEST L For evaluating soil systemic control of Colorado potato beetle (Leptinotarsa decemlineata), transplanted tomato plants were grown in 6-cm pots for 5 days until they were at the two true leaf stage.

Test compounds were dissolved in 0.25 mL of acetone and diluted with water provide solutions of 5 ppm. Five L of the appropriate test solution was applied by pipette to the surface of the soil in each pot, followed by 5 mL of water, with eight plants for each compound/rate. The pots were covered and held at 25 °C with 16 hours of light per day. The plants were watered the next day and each day following as needed. After 4 days, one leaf from each plant was excised and placed into a well of a test tray as described in Test H. One 5-day old Colorado potato beetle (Leptinotarsa decemlineata) was placed in each well, the tray was covered and then the test units were held at at 25 °C with 16 hours of light per day. Mortality was observed after four days. Of the compounds tested, the following provided excellent levels of mortality and feeding inhibition at 5 ppm: 214.

TEST M For evaluating control of boll weevil (Anthonomus g. grandis), samples of the test compounds were dissolved in 1 mL of acetone. This solution was then diluted to 100 mL total volume using an aqueous 500 ppm solution of Ortho X-77™ surfactant. Serial dilutions were made to obtain 50 mL of 50 ppm concentration. The diluted solutions of the test compounds were sprayed to run-off on three-week-old cotton plants. The plants were placed on a rotating turntable sprayer (10 rpm). Test solutions were applied using a flat fan air-assisted nozzle (Spraying Systems 122440) at 10 psi (69 kPa). Sprayed and dried plants were incased in a plastic cylinder. Twenty weevils were placed in each cylinder containing a whole cotton plant. At three days after infestation a feeding damage rating was taken.

Of the compounds tested, the following provided excellent levels of plant protection at 50 ppm (10% or less feeding damage): 530 and 531.

TEST N ■ For evaluating control of thrips (Frankliniella sp.), samples of the test compounds were dissolved in 1 mL of acetone. This solution was then diluted to 100 mL total volume using an aqueous 500 ppm solution of Ortho X-77™ surfactant. Serial dilutions were made to obtain 50 mL of 10 ppm concentration.

The diluted solutions of the test compounds were sprayed to run-off on three- week-old cotton or soybean plants infested with thrips. The plants were placed on a rotating turntable sprayer (10 rpm). Test solutions were applied using a flat fan air-assisted nozzle (Spraying

Systems 122440) at 10 psi (69 kPa). Sprayed and dried plants were incased in a plastic cylinder. At four days after apphcation the total number of dead thrips was recorded.

Of the compounds tested, the following resulted in at least 90% mortality at 10 ppm: 542.

TEST O Test O followed an alternative protocol for evaluating control of Colorado potato beetle (Leptinotarsa decemlineate). Several hours prior to spraying, 5 mg (100% active ingredient, ai) of the test compounds were dissolved in 1 mL of acetone. Using the aqueous solution of 500 ppm of Ortho X-77™, the sample bottle was rinsed and added to the test compounds. This sample solution was then brought to 100 mL with the aqueous solution. Serial dilutions are made to obtain 50 mL of 10 ppm.

Formulated experimental compounds were sprayed to run-off on three week old potato or tomato plants. The plants were placed on a rotating turntable sprayer (10 rpm). Test solutions were applied using a flat fan air-assisted nozzle (Spraying Systems 122440) at 10 psi (69 KPa). Once the plants were dried, leaves were excised from the treated plant. The leaves were cut, and then the pieces were placed singly into a 5.5 cm-by-3.5 cm cell of a sixteen-well plastic tray. Each cell contained a 2.5 square of moistened chromatography paper to prevent desiccation. One second instar larvae was placed in each cell. At three days after infestation total number of dead Colorado potato beetles was recorded.

Of the compounds tested, the following resulted in at least 90% mortality at 10 ppm: 497, 500, 530, 543, 544, 558, 562 and 684. TEST P Seventy-eight cotton plants were grown in the greenhouse with natural Hghting in Sassafras soil in six inch pots. When six true leaves were on the plant (approximately 36 cm tall) the soil was drenched with a solution of Compound 497, 500, 530, 531 or 543. Each of the 5 compounds was dissolved in 2 mL of acetone, and distilled water was added to make 300 ppm solutions of each of the compounds. The pots were divided into six groups (13 plants / treatment), and 10 mL of each solution was applied over the soil surface of each group with one group left untreated. The plants were arranged in the greenhouse in a randomized block design. Each treatment was divided into three groups for sampling at 24, 48, and 96 hours.

Leaves were taken from the base and terminal of the plants. The leaves from the third node and the terminal leaves greater than 15 cm² were sampled per plant. One clipped leaf from each plant was cut into four pieces and each piece was placed into an well with one second-instar larvae of Heliothis virescens (tobacco budworm). Larval mortality (%M) was recorded 96 hours after sampling. The percentage of leaf feeding (%FF) was also recorded. Consumption of the leaf in the well was reported as 0 - 100% (0 equals no feeding). Results are listed in Table P.
