Description
The present invention relates to active compound combinations which are very suitable for controlling phytopathogenic fungi, comprising compounds of the formula I and further known fungicidally active compounds.
It is known that the compounds of the formula I have fungicidal properties (DE-19602095). The activity of this compound is good, but its effect at low application rates is always unsatisfactory.
Furthermore, numerous pyrrole derivatives, aromatic carboxylic acid derivatives, morpholine compounds and other heterocycles are known to be useful for controlling fungi (cf.: Buchel, "Pflanzenschutz undSchadlinsbekampung", pages 87, 136, 140, 141 and 146 to 153, Georg Thieme Verlag, Stuttgart 1977). However, the activity of the compounds described is unsatisfactory at low application rates.
The present invention therefore provides novel active compound combinations comprising compounds of the formula IAnd at least one mixed component (A) propineb (Antrocol) and/or (B) benflurosulfamide (dichlorfluanide) and/or tolylfluanide (tolyfluoride) and/or (C) bitertanol and/or (D) tebuconazole and/or (E) triazolone and/or (F) triadimenol and/or (G) Imidacloprid and/or (H) procymidone and/or (II) mancozeb and/or (K) folpet and/or (L) dimethomorph and/or (M) cyazofamid and/or (N) metalaxyl and/or (O) fosetyl-Al and/or (P) famodone and/or (Q) tetramethol and/or (R) fosetyl-Al) and/or (P) fosetyl-xylene and/or (Q) pyrifenozide and/or (R) metrine and/or (R) metocloprid and/or (W) metocloprid and/or (V) metocloprid and/or (W) metoclopramide and/or (L) metocloprid and/or (M) prochloraz and/or (S) propineb and/or (S) and/or (W) propineb and/or (N) and/or (Y) fludioxonil and/or (Z) fenpiclonil andor (alpha) sitidine (Guazatine) and/or (beta) ethyl valacil and/or (chi) [ 2-methyl-1 [ [1- (4-methylphenyl) ethyl ] ethyl]Amino group]Carbonyl radical]Propyl radical]Carboxylic acid 1-methylethyl ester and/or (delta) 8-tert-butyl-2- (N-ethyl-N-N-propylamino) -methyl-1, 4-dioxaspiro [5, 4 ]]Decane and/or (. epsilon.) 2, 3-dichloro-4- (1-methylcyclohexylamido) -phenol and/or (. omega.)

The composition has very good fungicidal property, and the components complement each other to realize synergistic effect.
Active compounds of the formula I are known (DE 19602095). Other components in the compositions according to the invention are also known.
In addition to the active compounds of the formula I, the active compound compositions according to the invention comprise at least one active compound selected from the compounds (A) to (VI). Furthermore, further fungicidally active additives may additionally be present.
The synergistic effect of the compositions is particularly pronounced when the active compounds in the active compound compositions according to the invention are present in a certain weight ratio. However, the proportion by weight of active compound in the active compound composition can vary within a relatively wide range. In general, the parts by weight of active compounds (A) to (VI) are from 0.01 to 50, preferably from 0.25 to 20, per part by weight of active compound of the formula I.
In particular, the stated parts by weight of the following individual mixture components are, for each part of the compound of the formula I: (A) 1: 1 to 1: 50, preferably 1: 5 to 1: 20(B) 1: 1 to 1: 50, preferably 1: 1 to 1: 20(C) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(D) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(E) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(F) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(G) 20: 1 to 1: 20, preferably 10: 1 to 1: 10(H) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(II) 1: 1 to 1: 50, preferably 1: 5 to 1: 20(K) 1: 1 to 1: 1, preferably 1: 5 to 1: 20(L) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(M) 10: 1 to 1: 10, preferably 1: 5 to 1: 10 (K) 1: 1 to 1: 50, preferably 1: 5 to 1: 10 (N) 1: 1 to 1: 10, preferably 1: 5 to 1: 10 (O)10 to 1: 10, preferably 1: 10 (M)10 to 1: 10, preferably 1: 10 (N) 1: 1 to, preferably from 1: 1 to 1: 10(P) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(Q) 5: 1 to 1: 20, preferably from 1: 1 to 1: 10(R) 5: 1 to 1: 20, preferably from 1: 1 to 1: 10(S) 5: 1 to 1: 20, preferably from 1: 1 to 1: 10(T) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(U) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(V) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(W) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(X) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(Y) 10: 1 to 1: 10, preferably from 5: 1 to 1: 5(Z) 10: 1 to 1: 10, preferably from 5: 1 to 1: 10 (alpha) 10 to 1: 5 (beta) 10, preferably from 5: 1 to 1: 10, preferably from 5(Y)10 to 1: 1 to 1: 10, preferably from 5 (beta (50), preferably 20: 1 to 1: 10(χ) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(δ) 10: 1 to 1: 20, preferably 5: 1 to 1: 10 (. epsilon.) 10: 1 to 1: 10, preferably 5: 1 to 1: 5 (. omega.) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(π) 10: 1 to 1: 10, preferably 5: 1 to 1: 5(III) 5: 1 to 1: 50, preferably 1: 1 to 1: 20(IV) 10: 1 to 1: 10, preferably 4: 1 to 1: 4(VI) 10: 1 to 1: 10, preferably 4: 1 to 1: 4
The active compound combinations according to the invention have good fungicidal properties and can be used in particular for controlling phytopathogenic fungi, such as Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes, etc.
The active compound combinations according to the invention are particularly suitable for controlling cereal crop diseases, such as Erysiphe, Coccidioides, Sclerotium, Mucor, Septoria (Septoria spp.), Fusarium (Fusarium spp.), Pseudocercospora and Microcospora, and also for controlling fungal infections of non-cereal crops, such as wine, fruits, vegetables, such as Phytophthora, Plasmopara, Pythium, and Erysiphe, such as Sphingomonas or Undariomyces, and leaf spot disease-causing organisms, such as Venturia, Altemaria and Septoria, and Rhizoctonia, Botrytis, Sclerotium and Microsclerotium.
At the concentrations required for controlling plant diseases, the crop plants can have good tolerance to the active compound combinations. This fact allows us to treat aerial parts of plants, breeding stems and seeds, and the soil.
The active compound compositions according to the invention can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microcapsules and ultra-low-volume sprays, where the microcapsules are in a polymer and have a coating composition for the seed and an ULV formulation.
These formulations are prepared in a known manner, for example by mixing the active compounds or active compound combinations with extenders which are liquid solvents, pressurized liquefied gases, and/or solid carriers, and optionally with surfactants which are emulsifiers and/or dispersants, and/or foaming agents. If the filler used is water, it is possible to use, for example, organic solvents as auxiliaries. Basically, suitable solvent solutions include: aromatic compounds such as xylene, toluene or alkylnaphthalenes, chlorinated aromatic compounds or chlorinated aliphatic hydrocarbons such as chlorobenzene, dichloroethane or dichloromethane, aliphatic hydrocarbons such as cyclohexane or paraffins (alkanes), for example petroleum fractions, alcohols such as butanol or ethylene glycol and ethers or esters thereof, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulfoxide, or water. Liquefied gaseous extenders or carriers are liquids which are gaseous at ordinary temperature and pressure, for example aerosol propellants such as halogenated hydrocarbons and butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are, for example, natural mineral powders such as kaolin, clay, talc, chalk, quartz, attapulgite (attapulgite), montmorillonite or kieselguhr and synthetic mineral powders such as fine silica powders, aluminas and silicates. Suitable solid carriers for the preparation of granules are: for example, screened crushed natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or synthetic granules of inorganic or organic powders, and granules of organic materials such as sawdust, coconut shells, corn cobs and tobacco stalks. Suitable emulsifiers and/or foaming agents are, for example, nonionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, such as alkylaryl polyglycol ethers, alkylsulfonates, alkylsulfates, arylsulfonates or protein hydrolysates. Suitable dispersants are lignin-sulfite waste liquors and methylcellulose.
Tackifiers such as carboxymethylcellulose and natural and synthetic polymer powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate or natural phospholipids such as cephalins and lecithins and synthetic phospholipids, can be used. Other additives may be mineral and vegetable oils.
It is also possible to use colorants such as inorganic pigments, for example iron oxide, titanium tetroxide and Prussian blue, and organic dyes, for example alizarin dyes, azo dyes and metal phthalocyanine dyes, and also small amounts of nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations generally contain from 0.1 to 95% by weight of active compound, preferably from 0.5 to 90%.
The active compound combinations according to the invention can be used in various formulations as a mixture with other known active compounds, such as fungicides, insecticides, acaricides and herbicides, and also with fertilizers and plant growth regulators.
The active compound combinations can be used as such or in the form of ready-to-use solutions, emulsifiable concentrates, emulsions, suspensions, wettable powders, soluble powders and granules prepared therefrom.
They are used in the customary form, for example by watering, spraying, atomizing, broadcasting, spreading, treating a powder of dry seeds, treating a solution of seeds, treating a soluble powder of a slurry or applying the pesticide by cladding.
The active compound compositions in the form of their use can vary within considerable limits when treating parts of plants, and they are generally from 1 to 0.0001% by weight, preferably from 0.5 to 0.001%.
The treatment of seed usually requires from 0.001 to 50 g of active compound per kg of seed, preferably from 0.01 to 10 g.
For soil treatment, concentrations of active compound of from 0.00001 to 0.1% by weight, preferably from 0.0001 to 0.02%, are required at the site of use.
The active compound combinations according to the invention have a pronounced fungicidal synergistic activity according to the following examples. Although each active compound exhibits a weak fungicidal activity, the activity of the composition exceeds that of the simple sum of the activities of the individual compounds.
When the fungicidal activity of the active compound combinations exceeds the sum of the activities of the individual active compounds applied individually, then there is always a synergistic effect of the fungicides.
The expected activity of a given combination of two active compounds can be calculated according to the following formula (cf. Colby, s.r., "calculating synergistic and antagonistic activity of herbicides", "weeds" stages 15, pages 20 to 22, 1976):
if it is not
X is whenmppm concentration% of effect when applying active compound A,
y is such asnppm concentration the percentage of effect of active compound B applied,
e is when each ismppm andnppm concentration the percentage of effect of the active compounds A and B applied,
then
E=X+Y-(X·Y)/100
If the actual fungicidal activity exceeds the calculated value, the activity of the composition is super-additive, i.e. there is a synergistic effect. In this case, the actually observed effect must be larger than the expected effect value (E) calculated by the above equation. Example 1 Phytophthora (tomato) test/protective Activity
To determine the protective activity, commercial preparations of the active compounds are sprayed at the stated application rates onto young plants. After the spray layer has dried, an aqueous spore suspension of potato late blight (phytophthora infestans) is inoculated onto the plants. The plants were stored in an incubator at 20 ℃ and 100% relative air humidity.
The assay was performed three days after inoculation. 0% means the effect of the control, 100% means no infection.
The active compound combinations according to the invention have a pronounced fungicidal synergistic activity according to the following examples. Although each active compound exhibits a weak fungicidal activity, the activity of the composition exceeds that of the simple sum of the activities of the individual compounds.
When the fungicidal activity of the active compound combinations exceeds the sum of the activities of the individual active compounds applied individually, then there is always a synergistic effect of the fungicides.
The expected activity of a given combination of dual active compounds can be calculated according to the following formula (cf. Colby, s.r., "calculating synergistic and antagonistic activity of herbicides", "weeds" stage 15, pages 20-22, 1976):
if it is not
X is whenmppm concentration% of effect when applying active compound A,
y is such asnppm concentration the percentage of effect of active compound B applied,
e is when each ismppm andnppm concentration percent effect when applying active compound A,
then
E=X+Y-(X·Y)/100
If the actual fungicidal activity exceeds the calculated value, the activity of the composition is super-additive, i.e. there is a synergistic effect. In this case, the actually observed effect must be larger than the expected effect value (E) calculated by the above equation.
The following table clearly shows that the actual activity of the active compound compositions according to the invention is greater than the calculated activity, i.e. that there is a synergistic effect.TABLE 1Phytophthora assay (tomato)/amount of active compound(s) which protect the active compound(s) administered in g/ha units of effect% (I) 0.59(χ) 0.5 20Racemic amides of L-valineMixtures according to the invention

To determine the protective activity, commercial preparations of the active compounds are sprayed onto young plants at the stated application rates. After the sprayed layer had dried, two small pieces of agar covered with soybean downy mildew (Botrytis cinerea) were placed on each leaf. The plants were placed in a black room at 20 ℃ and 100% relative air humidity.
Infected leaf spot sizes were determined two days after inoculation. 0% means the effect of the control, 100% means no infection.
The active compound combinations according to the invention have a pronounced fungicidal synergistic activity according to the following examples. Although each active compound exhibits a weak fungicidal activity, the activity of the composition exceeds that of the simple sum of the activities of the individual compounds.
When the fungicidal activity of the active compound combinations exceeds the sum of the activities of the individual active compounds applied individually, then there is always a synergistic effect of the fungicides.
