 -o methods - common in the manufacture of preparative forms of pesticides. The content of the active substance in the formulation is in the range from 0.0001 to 10%, preferably from 0.01 to 1%. Example 1. A drug of the beginning of the beginning is sprayed before the drop formation of cabbage plants (Brassica cleracea) and caterpillar moths (Plutella maculipennis) are planted on them. After a certain time, the degree of death of the larvae (%) is determined, and 100% means that all the caterpillars died, 0% means that none of the Hosekipa died. The active principles, their concentrations, the timing of determination and the results are shown in Table. 1. Example 2. The leaves of cotton (Gossypium hirsutum) 1 are sprayed with the preparation of the active principle and the caterpillars (Laphygma exigua) are planted on them. After a certain time, the degree of death of the larvae (%) is determined, and 100% means that all the caterpillars have been hunted, and 0% means that not a single caterpillar has died. The active principles, their concentrations, the timing of determination, and the results are shown in Table 2. Example 3. The leaves of cabbage (Brassica oleracea) are sprayed with the preparation of the active principle before dropping and the larvae of the horseradish leaf beetle (Phaedon cochlearial) are planted on them.

The effective principles, "x concentration, definitions and results are given in abl. 3. Example 4. Experience with parasitic fly larvae. Approximately 20 fly larvae (Licilia cuprina) are placed in a test tube containing approximately 2 cm of horse muscles. 0.5 ml of the drug of the active principle is applied to this loschadinoe mso. At the end of the day, the degree of death of the larvae (%) is determined; at that, 100% means that all the larvae died, 0% means that not one larva died. The investigated active principles, the applied concentrations of the active principle and the results obtained are presented in Table. 4. Formula of the invention: Insecticidal agent, including benzoylurea derivatives as an active substance, as well as an additive selected from the group: solvent, dispersant, emulsifier, characterized in that, in order to enhance insecticidal activity, it contains a compound common as benzoylurea derivatives Formulas G.,; - Г II- / VcO-r5H-CO-No. IRR K
