Problems solved by technology

[0004] The current pest control not only has poor control effect, but also uses different pesticides for different pests, which consumes a lot of manpower, material resources and financial resources, and also causes environmental pollution, and the continuous use of pesticides with a single active ingredient susceptible to drug resistance

Embodiment

[0056] (1) Biological detection of synergistic effect

[0057] Sun Yunpei (Sun Y-P) method was used to evaluate the mixed effect of the two active ingredients in the insecticide composition of the present invention by calculating the co-toxicity coefficient (CTC), as follows:

[0058] Evaluation criteria: when CTC ≥ 120, it shows a synergistic effect; when CTC ≤ 80, it shows an antagonistic effect; 80 < CTC < 120, it shows an additive effect.

[0059] Calculation formula:

[0060] Co-toxicity coefficient (CTC) = [mixture actual toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

[0061] Mixture Actual Toxicity Index (ATI) = (LC of standard drug 50 / Mixed LC 50 )×100

[0062] Mixture theoretical toxicity index (TTI) = TI of agent A × content of A in the active ingredient of the mixture + TI of agent B × content of B in the active ingredient of the mixture

[0063] Toxicity index (TI) = (LC of standard agent 50 / LC of test agent 50 )×100 (take one of A...

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.

Description

technical field [0001] The present invention relates to a kind of insecticide composition and insecticide and application thereof, specifically, relates to a kind of insecticide composition containing indoxacarb and organophosphorus insecticide, and the insecticide composition The prepared insecticide and the application of the insecticide in controlling plant pests. Background technique [0002] In agricultural production practice, there are often problems of mixed occurrence of different types of pests, rice leaf roller, rice planthopper, rice stem borer, stem borer, thrips, rice thrips, rice water weevil, diamondback moth, beet armyworm, Spodoptera litura, aphids and cotton bollworms are pests that often exist simultaneously or successively, for example, on rice, cotton, cruciferous vegetables, fruit trees and other crops. [0003] For the above common pests, it is often necessary to use different insecticides for control. For example, the rice leaf roller is generally c...
