Biologically active substances are thoroughly mixed in mixers and grind on the appropriate mills and rollers. Wettable powders are obtained which can be diluted with water to suspensions of any desired concentrations. Emulsifiable concentrates. For the preparation of a) 10%, b) 25%, and c) 50% emulsifiable concentrate, the following substances are used, parts by weight: a) 10 biologically active substances, epoxidized vegetable oil 3.4 of a combined emulsifier, consisting from a polyglycolic ester of fatty alcohol and calcium skylaryl sulfonate, 40 dimethylformamide, 43.2 xylene; b) 25 biologically active substances, 2.5 epoxidized vegetable oil, 10 mixtures of aryl alkyl sulfonate with polyglycolic ether of fatty alcohol, 5 dimethylformamide; 57.5 xylene; c) 50 biologically active substances, 4.2 polyglycol ether tributylphenol a, 5.8 calcium dodecylbenzenesulfonate, 20 cyclohexanone, 20 xylene. Emulsions of any desired concentration can be made from such concentrates by diluting with water. Spraying agent. 5 For the preparation of a) 5% and b) 95% of the drug for the spray, the following substances are used, parts by weight: a) 5 biologically active substances, 1 epichlorohydrin, 94 gasoline (bp 1 O-1900s ); b) 95 biologically active substances, 5 epichlorohydrin. Example 1. -A). Insecticidal action as intestinal yes. Cotton plants are sprayed with 0.05% aqueous emulsion of a biologically active substance (obtained from a 10% emulsifiable concentrate): 10 parts by weight biologically active substance, 3.4 wt.h. epoxidized vegetable oil, 3.4 combined emulsifier consisting of polyglycolic ether of fatty alcohol and calcium salt, alkyl aryl sulfonate, 40 parts by weight dimethylformamide, 43.2 weight.h. xylene. After spraying, the Lj larvae of the Spodoptege EittoraEis and HePothis virescens stages are placed on the plants. The test was carried out at 24 ° C and relative air humidity of 60%. The compounds in the above test show a good insecticidal action as intestinal and against the larvae of Spodoptera and HeEiothis. B) Systemic insecticidal action To establish a systemic effect, the established legume plants of Vicia faba are placed in a 0.1% aqueous solution of a biologically active substance (obtained from a 10% emulsified concentrate). After 24 hours on the terrestrial parts of the plants put aphids Aphis fabae. Special device animals protect from contact and exposure to. The test was carried out at 24 ° C and relative air humidity of 70%. The compounds in the above test show a systemic insecticidal action against Aphis fabae. Example 3. Action against Chifco suppressaEis. 6 rice plants of the variety Caloro are planted in plastic pots, which have an upper diameter of 17 cm and are grown to a height of about 60 s. Infection with the help of Chi6o suppressaBis L- larvae) is carried out 2 days after the addition of the biologically active substance in the form of granulates consumption of 8 kg of active substance per hectare) in rice water. An insecticidal rating of 7 is carried out 10 days after the addition of the granulate. The compounds in the above test are active against ChiEo suppfessaBis, Example 4. Acaricidal action. 12 days before the test for acaricidal action, plants of haricot beans are covered with infected pieces of leaf from the population of Tetranychus -urticae. Grown mobile plants are sprayed with an emulsified and test preparation so that the solution does not run off, then the plants are kept in a greenhouse at. After 2-7 days, the effect of the drug on the larvae, adults and eggs, was evaluated, the results are expressed as a percentage. Example 5. Action against ticks. A) Rhipicephatus burra. Five adult Ixodus mites or 50 larvae of Ixodes mites are placed in glass tubes and immersed for 2 min in 2 ml of water dilution emulsion with the amount of the test substance of 100, 10.1, or 0.1 million. from a 10% emulsion concentrate. The tubules are covered with cotton and set vertically. Evaluation was carried out for adults after 2 weeks and for larvae, after 2 days. B) BoophiEus microp us (larvae). Using a similar dilution series, as in test A), experiments were conducted with 20 sensitive, OP-resistant larvae (resistance refers to compatibility with diazinon). The compounds of Example 1B in this test are active against adults and larvae of RhipicephaRis burra and sensitive, respectively, OP-resistant larvae of BoophiEus micropfus. Example 6. Action against Erysiphe grarninis on the multi-bottom barley. After 48 hours, the treated plants infect with the fungus conidia. Infected barley plants are placed in a greenhouse and fungal damage is assessed after 10 days. In tab. 2 shows the comparative data on the activity of various compounds of the active principle of the general formula I, their concentration in million dollars xdl of 100% mortality of various insect species.
