The compounds of the general formula (J) have little toxicity against warm-blooded ones. These compounds may be used. practically as independently, and together with the corresponding fillers and / or other additives, which can be solid or liquid. They are selected according to the required form of application. Based on compounds of the general formula (I), IVIL agents, emulsified concentrates, granules, dispersions, spraying agents, solutions or suspension agents are prepared using the inventive method, for example by thoroughly moving and / or using the general formula (1) with appropriate fillers, in particular by adding dispersants or solvents that are inert to AB On the basis of AB according to the invention, insecticide preparations can be prepared in the form of a preparation ov for filing, soil application, coated granules and for impregnation, water dispersions (wettable powders), nacTv E1 on water, aerosol. With the aim of producing 5% oGEN, a 5% weight preparation is used, h. AB, 95 h-talc; and drug 2h. AB, 1 part of highly dispersed cremic acid and 97 parts of talc. AB is lured and crushed with fillings. To prepare a 5% granulate, eat the following substances (parts by weight); B 5, epichlorohydrin 0.25, cytylsilicol ether 0.25, half ethnlenglyole 3.50, kaolin 91 (grain size, 3-0.8 mm). AB is mixed with epichlorohydrin and dissolved in 6 parts by weight. acetone, followed by the addition of polyethylene glycol and e or polyglyl splendid ether. The resulting solution is sprayed onto kaolin and then acetone is evaporated in vacuo. Wettable powder. To obtain a) 40%, b) and c), d) 10% wettable powder, the following components are used (parts by weight): a) AB 40, sodium salt of lignins acid, 5, sodium salt of di-butyl naphthalene sulfonic acid 1 , silicic acid 54 b) AB 25, calcium ligninsulfonate 4.5, a mixture of chalk from Champagne and hydroxyethylcellulose (1; 1) 1p9, sodium dibutylnaphthalene sulfonate 1.5, silicic acid from Champagne 19.5, kaolin 28.1; c) AB 25, isooctylphenoxypolyoxyethylene ethanol 2.5, a mixture of chalk from Champagne and hydroxyethylcellulose (G1) 1.7, sodium aluminum silicate 8.3, infusorious earth 16.5, kaolin 46; d) AB 10, a mixture of sodium salts of saturated sulphates of fatty alcohol 3, condensate of naphthalene sulfonic acid and formaldehyde 5, kaolin 82.. The active ingredients are thoroughly mixed in appropriate mixers with fillers and crushed in appropriate mills and rollers. Wettable powders are obtained which can be diluted with water to a suspension of any desired concentration. To prepare a) 10%, b) 25% and c) 50% emulsifiable concentrate, use the following substances (in parts): a) AB 10, 3 × oxidized vegetable oil, combined emulsifier, consisting of a fatty alcohol polyglycolic ester and a calcium carbonate alkylaryl sulfonate 3.4, Lymethylformamide 40, xylene 43.2; b) AB 25I epoxidized vegetable oil 2.5, a mixture of alkylaryl sulfonate and polyglycolic ether of fatty alcohol 10, dimethylformamide 5, xylene 57.5; (e) AB 50, tributylphenol polyglycol ether 4.2, cyclohexanone 20, calcium dodecylbenzenesulfonate 5.8, xylene 20; Emulsions of any desired concentration are prepared from such concentrates by diluting with water. 5, In order to obtain a) 5% spray preparation, 5 parts by weight are used. AB, 1 hour epichlorohydrin and 94 parts of gasoline (boiling range 160ISO C), and 95% - 95 parts of AB and 5 hours of epichlorohydrin. In the experiments described below, the biologically active action of various ABs on pupae, larvae, eggs of various insects is shown. Experience. Contact action of the pupa Tenebfio motitop. A certain part of O, 1% solution of AB in acetone, corresponding to the retention of AB Yu mg / m, is pipetted into the aluminum cup and distributed equally and charged. After evaporation of the acetone, 10 freshly raised pupae are placed on the surface. -itof Then the cup is closed with a net lid. After untreated control insects crawled out of the puppet shell, the experimental insects that had been treated as described above were examined for the number of normal animals. Score of 5 points - 100% of lethal special forms (extracules and adultoids), 4 points - lethal special forms and non-lethal special (adultoids), 3 points - lethal special forms, non-lethal. Special №L and normal adults, 2 points non-lethal special fords normal addicts, 1 point - 100% normal ™ adults. Experiment 2. Contact action on the larvae 3) sepcu3-fa5ciatu5 A certain part of 0.1% diluent AB in acetone is corresponding to the content of the AVY mg / m pipette clearly in an aluminum pan and evenly distributed. After evaporation of the acetone, 10 larvae of the fifth stage are placed on the treated surface of the cup, on which food and moisture are placed on cotton wool. Then the cup is closed with a mesh lid. After 10 days, i.e., when the utile molting of untreated control larvae occurred, the experimental insects that developed in the above-described larvae were examined for the number of normal adultosis. Evaluation: 5 points 100% lethal ik of special forms (deceased during shedding and extraparts), 4 points lethal special forms and non-fleeting special forms (adultoids), 3 points lethal special forms, non-lethal special forms and normal adultsJ, 2 points - non-lethal special fords and normal addicts, 1 point - 100%. normal adultov. Experiment 3. Effect on eggs Spo opteca tiitorafis The eggs of upodoptefo tittoraEis are immersed in 0, a solution of AB in a mixture of acetone and water, then they are removed ™ from a rasteror and kept at 25 ° C. The number of larvae that hatched from them is kept at 25 ° C. 10 treated eggs; Evaluation; 5 points - no spoilage of the larvae (100% effect), 4 points - only 10% of the treated eggs hatched PERSONS (efficacy), 1 point - 90% of the eggs processed hatched 5 -; - 1 1nkki (0 % efficiency) c Experience 4, Effect on /: Nchi: Ki Mizsa domest caB cups add snow to the green nutrient substrate (CSMA) for Muscc domesticc larvae 50 g each and then with a Hasc pipette a certain amount of li-HO the acetone solution to obtain in the substrate-concentration AB 0.1, 0.5 and O01% C evaporate s for 20 hours) Then put 25 o in the cups. nodnevnyh larvae Muscos domeetica- after converting them into pupae last separated from the substrate pro1 "yvkoy vsosudah water and kept closed mesh lids. The toxic effect of AB on the development of larvae was determined from the number of emerging pupae from the initial mixture. After 1.0 days, the nol -;; of the short hatches of the pupae of the flies were determined and the effect of AB on the transgarden was determined.
