[0055] Example

[0056] (1) Bioassay for synergistic effect

[0057] The Sun Y-P method is used to calculate the co-toxicity coefficient (CTC) to evaluate the mixing effect of the two active ingredients in the pesticide composition of the present invention, as follows:

[0058] Evaluation criteria: when CTC≥120, it shows synergistic effect; when CTC≤80, it shows antagonism; 80

[0059] Calculation formula:

[0060] Co-toxicity coefficient (CTC)=[Actual toxicity index of the mixture (ATI) / Theoretical toxicity index of the mixture (TTI)]×100

[0061] The actual toxicity index of the mixture (ATI) = (LC of the standard agent 50 / Mixed LC 50 )×100

[0062] Theoretical Toxicity Index (TTI) of the mixture = TI of agent A × content of A in the active ingredient of the mixture + TI of agent B × content of B in the effective ingredient of the mixture

[0063] Toxicity Index (TI) = (LC of standard medicine 50 / LC of test agent 50 )×100 (use one of A and B as the standa...

Abstract

The invention relates to an insecticide composition. The composition contains active ingredients and is characterized in that the active ingredients contain indoxacarb and an organophosphorus insecticide, wherein the organophosphorus insecticide is selected from at least one of acephate, fenitrothion and malathion, and the weight ratio of indoxacarb to the organophosphorus insecticide is 1: (0.01-90). The invention further relates to an insecticide prepared from the insecticide composition and application of the insecticide in the prevention and control of one or more plant pests. Compared with single-ingredient indoxacarb or organophosphorus insecticide, the insecticide composition and the insecticide, disclosed by the invention, have a synergized action, and the prevention and control effect can be improved; the insecticide duration is long; due to non-single active ingredients, the insecticide resistance is difficult to produce; and multiple different species of pests occurring in a mixed manner can be prevented and controlled, so that the dosage can be reduced, the cost is saved, and the pollution to the environment is reduced.
