Approximately 20 m of sprouted rice seedlings are placed for growing in cups with a diameter 9 cm, 3 cm high. After vygradavan vkhodov, having a height of 1-2 cm, they are doused with aqueous dksperk m of a given concentration at a ratio of 2 ng cup, then dried, let the rice stem larvae start, just above the mixture, and the cups are closed . After 10 days of treatment with the dispersion, the number of dead larvae is counted and the death rate is calculated.

Young branches of a persimmon tree (Persimmon Ponskoy) are cut to a length of 15 cm, starting from the top, and immersed in aqueous dispersions of N- (2-chlorobenzoyl) -Y- 3-chloro-4- {3, 5-dichloropyridyl-2 -oxy) -phenyl-carbamide of various concentrations from 10 s. Then they are dried and placed in wide-necked flasks. Larvae of epic silk moth are placed in each of them at 2-3 stages of development. The skins are covered with gauze and kept at a constant temperature when illuminated. After 7 and 15 days of treatment with the dispersion, the number of dead larvae was counted and the death rate was calculated, as well as the coefficients deviating from the usual ones, the results are shown in Table 4,
