Description

The invention relates to an insecticoacaricidal agent which can be used to combat various types of pests of the animal and plant world, especially to combat cotton pests. It is known to use for such a preparation a preparation that includes various types of additives and the active substance phenotrin 1 of general formula I CH3 CH3; yS CH-CH-CH-SOOCH However, the known drug is not sufficiently active against cotton pests. The aim of the invention is the expansion of insecticoacaricidal agents exhibiting higher activity compared with the known preparation. The goal is achieved by an insecticoacaricidal agent, including various additives and an active substance based on benzyl esters of unsaturated carboxylic acids, the distinguishing feature of which is that benzyl esters of the unsaturated carboxylic acids are used as benzyl esters of the formula II SKZ, CH2 f T / VCH CH-CH-C-0-CK-t / I 1 where Y is hydrogen, chlorine, methyl, in an amount of 0.1-95 wt.%, The rest is additives. The compounds of formula II are suitable for controlling various types of pests of the animal and plant world. Compounds of formula II are particularly suitable for controlling insects, phytopathogenic mites of the species Lepidoptega, CoEeoptera, Homoptera, Heteroptera, Diptera, Acarina, Thysonoptera, Orthoptera, AnopEura, Siphonoptera, MaEtophapa, Tbysanura, ours, ours, ours, ours, ours, ours. First of all, the compounds of the formula I are suitable for the control of insects that are pests of plants, especially the MoMB, ornamental and useful plants, are particularly suitable for the control of cotton pests (for example, against Spodopte ralitloralis u. HeSidnis viresceps and vegetable crops (for example, LeptinoEcirsa decemtineata and others).

The effective substances of formula 11 also show a very favorable action against flies, for example, Miisca domesticaumuchen Carven.

The acaricidal or insecticidal effect can be significantly extended by the addition of other insecticides and / or acaricides and made into appropriate preparations. Suitable additives are, for example, phosphorus compounds; nitrophenols and their derivatives; urea formamidines; other compounds such as pyrethrin, as well as carbamates and chlorinated hydrocarbons.

The compounds of the formula II can be used with suitable carriers and / or additives, such additives can be liquid or solid substances corresponding to those used in the preparation of preparations.

The preparation of the agents according to the invention is carried out by known methods as a result of the fine mixing and / or grinding of effective substances of the formula I with suitable carriers, in an appropriate case, by adding dispersants which are inert with respect to the active substances — or solvents. The active substances can exist and be used in ready-made forms — solid preparations: powders for spraying, preparations for introducing into the soil in the form of granules, granulates (coated granules, impregnated granules and homogeneous granules); liquid preparations: a) concentrate effective substances capable of dispersing in water; wettable powders, pastes, emulsions; b) solutions.

Preparations based on compounds of the formula I are prepared as follows.

Powders for spraying.

To obtain a 5% powder, 5 parts of an effective substance are used for spraying, 95 parts of talc; for a 2% powder, 2 parts of an effective substance, 1 part of a high dispersion. hydrochloric acid, 97 parts of talc.

The effective substance is mixed with carriers and crushed.

Pellet t.

To obtain a 5% granulate

: 5 parts of the effective substance are used, 0.25 parts of epichlorohydrin, 0.25 parts of cetyl polyglycol ether, 3.50 parts of poly (ethylene glycol), .91 parts of kaolin (grain size 0.3-0.8 mm).

The active substance is mixed with epichlorohydrin and dissolved in 6 parts of acetone, polyethylene glycol and cetyl polyglycol ether are added to this. The solution thus obtained is sprayed onto kaolin and immediately thereafter acetone is evaporated into the vicarum.

Wettable powders.

To obtain a 40% -nHr wetting powder, 40 parts of an effective substance, 5 parts of sodium lignine sulfonic acid, 1 part of sodium salt of dibutylnaphthalenesulfonic acid, 54 parts of silicic acid are used.

For a 25% wettable powder, 25 parts of an effective substance, 4.5 parts of calcium ligninsulfonate, 1.9 parts of champagne (chalk - oxytythylcellulose, 1: 1 mixture), 1.5 parts of sodium dibutylnaphthalene sulfonate, 19.5 parts of silicic acid, 19 , 5 parts of chamapagne - chalk, 28.1 parts of kaolin;

or 25 parts of an effective substance, 2.5 parts of isooctylphenoxypolyethylene ethanol, 1.7 parts of a mixture of mela- and hydroxyethylcellulose (1: 1), 8.3 parts of sodium aluminum aluminum silicate, 16.5 parts of silica gel, 46 parts of kaolin.

For a 10% powder, 10 parts of an effective substance, 3 parts of a mixture of sodium salts of sulfates, saturated fatty alcohols, 5 parts of naphthalene sulfonic acid condensate and formaldehyde, 82 parts of kaolin are taken.

The effective substance is finely mixed in suitable mixers with additives and ground in suitable mills or rolls. Wettable powders are obtained which can be diluted with water to a suspension of any desired concentration.

The following substances are used to prepare an emulsifiable concentrate.

For 10% take 10 parts of the effective substance, 3.4 parts of epoxidized vegetable oil; 3.4 parts of combined emulsifier consisting of polyglycolic ether, dried alcohol and calcium salt of alkyl aryl sulfonate, 40 parts of dimethylformamide, 43.2 parts of xylene

For 25%, 25 parts of the effective substance, 2.5 parts of epoxidized vegetable oil, 10 parts of a mixture of alkylaryl sulfonate and polyglycolic ether of fatty alcohol are taken. 5 parts dimethylformamide, 57.5 parts xylene.

For 50%, 50 parts of an effective substance, 4.2 parts of tributylphenol polyglycolic ether, 5.8 parts of calcium-dodecylbenzenesulfonate, 20 parts of cyclohexanone, 20 parts of xylene are used.

From such concentrates, emulsions of any desired concentration can be obtained by diluting with water.

Sprayed.

The following ingredients are used to form the spray.

For 5%, 5 parts of the effective substance are used, 1 part of epiclofilpine and 94 parts of gasoline, the boiling range is 160-190 ° C. . For 95% 95 parts of an effective substance, 5 parts of epichlorohydrin.

Example 1

A. Action against insecticidal feed dov. Plants of cotton spray 1-zt of a 0.050% aqueous emulsion of an effective substance (obtained from a 10% emulsifiable concentrate in water).

After the layer dries, the larvae of L. Spodoptera eittoraEis u HeEothis were planted on cotton plants.

virescens. Experience at 60% relative humidity was carried out at.

The compounds according to Example 1 in the above test showed a good insecticidal action against food pests such as Spodoptera and Hediothis larvae.

B. Systemic insecticidal action. To establish a systemic effect, leguminous plants with the root system of Vicia faba were placed in a 010% aqueous solution of an effective substance. After 24 hours, Aphis fabae were placed on parts of plants that were above the ground. With the help of special devices, insects were protected from contact and gas exposure.

The experiment was carried out at 70% relative humidity.

The table presents the data of the activity of the proposed compounds in comparison with the known ones.
