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

[0047] (1) Biological detection of synergistic effect

[0048] 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:

[0049] 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.

[0050] Calculation formula:

[0051] Co-toxicity coefficient (CTC) = [mixture actual toxicity index (ATI) / mixture theoretical toxicity index (TTI)] × 100

[0052] Mixture Actual Toxicity Index (ATI) = (LC of standard drug 50 / Mixed LC 50 )×100

[0053] 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

[0054] 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 thiamethoxam and methidathion, wherein the weight ratio of thiamethoxam to methidathion is 1: (0.01-90). The invention further relates to an insecticide prepared from the insecticide composition. A dosage form of the insecticide is cream, water emulsion, micro-emulsion, water suspension, oil suspension, microcapsule suspension, wettable powder, water dispersible granule, soluble powder or soluble granule. The invention further relates to application of the insecticide in the prevention and control of one or more plant pests, such as scale insects, arrowhead scales, leafhoppers, thrips, aphid, white flies, mirid bugs, striped flea-beetles, leaf miners and spiny white flies. Compared with single-ingredient thiamethoxam or methidathion, the insecticide composition and the insecticide, disclosed by the invention, have a synergized action, and the prevention and control effect can be improved; 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.

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 thiamethoxam and methapon, and the insecticide prepared by the insecticide composition 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, such as scale insects, arrow scales, leafhoppers, thrips, aphids, whiteflies, mirid bugs, yellow striped beetles, leaf miners and black spiny whiteflies It is a pest that often exists simultaneously or successively, such as on citrus, tobacco, vegetables, rice, cotton, tea trees, fruit trees, flowers and other economic crops. [0003] For the common pests mentioned above, different insecticides are usually used for control. For example, scale insects are generally controlled ...
