    tesA 1 The invention relates to chemical means for combating agricultural pests, namely, an insecticidal composition containing O, O-dimethyl-3-phthalimidomethyl dithiophosphate and a synergist. The aim of the invention is to enhance insecticidal activity. Experimental Procedure Testing was carried out using the phosphite co-combinations of 0,0-dimethyl-3- {M-phthalimidomethyl) dithiophosphate and benzurone-H- (2,6-difluorobenoyl) -Y- (4-chlorophenyl) carbamide diflu 1: 1 ratio and a known composition containing phosmet and 0,0-dimeti-0-phenylthiophosphate, as well as the indicated individual insecticides against three harmful insects: scoops n Trichoplusia ni (Nipet), scoops Heiiothus verescens (Fabricius) and beetroot Spodoptera exigua. The following test methods are used. Trichoplusia ni (Hubner) activity test against scoop, Test compounds are dissolved in acetone-water mixture (50/50). A share of 1 1.5 inches (2.54 3.8 cm) pumpkin Ca5abacita abobrinha is immersed in the test solutions for 2-3 seconds and then laid out on a wire sieve to dry. Dried leaves are placed in Petri dishes containing moistened pieces of filter paper, and infected with five larvae of the NO scoop in the second age stage. After five days thereafter, the dead larvae were counted and the percentage of mortality was calculated. The test for activity against scoops Heliothus virescens (Fabricius).
    Table 1-17 The test compounds are dissolved in acetone-water (50/50). The cotton seed (Gossypium hirsu-. Turn) is immersed in the test solutions for 2–3 s and then on a wire strainer to dry. Dried leaves are placed in Petri dishes containing moistened pieces of filter paper and infected with five larvae of the scoop in the second age stage. After 5 days thereafter, the number of dead larvae is calculated and the percentage of mortality is calculated. A test for activity against Spodoptera exigua beetroot wormworm. The test compounds were dissolved in acetone-water (50/50). The seeds of Beta vuZgaris sugar beet are immersed in the test solutions for 2–3 s and then transferred to a wire strainer to dry. Dried leaves are placed in Petri dishes, at the bottom of which are placed moistened pieces of filter paper, and infect them with beet larvae of the worm in the fifth age stage. Five days after this, the number of dead larvae is counted and the mortality rate is calculated. The concentration of the solutions tested in this series of experiments varies from 0.1% to the concentration at which approximately 50% mortality of the larvae is recorded (calculated using the dose dependence curves used - percentage mortality). The values of LD, thus obtained, are given in table. 1. (average of four repeated runs).

    Coefficient of toxicity
    The actually observed or actual toxicity index is determined by dividing the LD value; the more active individual component (standard) by the LODD mix. The actual toxicity index of the mixture
    The more active ingredient for the scoop is neither phosmet, and for the scoop and beetroot wormworm - diflubenzuron.
    Theoretical toxicity index of the mixture - the actual toxicity index of component A is the percentage of components A in the mixture + + (real toxic index) The valid toxicity index of each component
    If the component under question is a standard component, this value becomes 100.
