Abstract

The invention discloses a high-efficient pesticide combination containing chlorpyrifos. The combination is mainly characterized by comprising active ingredients A and chlorpyrifos, wherein the active ingredients A are selected from thiamethoxam and thiacloprid, the weight ratio of the active ingredients A to the chlorpyrifos is (1:1)-(1:15), and the combination can be prepared into suspoemulsion, a microcapsule suspending agent and microcapsule suspension. The combination provided by the invention can be used for preventing and treating various insect pests, has an obvious synergistic effect, expands a preventing and treating spectrum, has high activity on the insect pests on cereal crops, ornamental plants, tea trees, vegetables, cottons and fruit trees, has a slow release function, reduces the using amount of the pesticide, is safe to human and livestock, is free of chemical injury, and has good environment compatibility; the preparation has enhanced binding performance, is resistant to rain wash, has long residual activity and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a high-efficiency pesticide composition containing chlorpyrifos. Background technique [0002] Chlorpyrifos (chlorpyrifos) chemical name: O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) phosphorothioate, molecular formula: C 9 h 11 Cl 3 NO 3 PS, chlorpyrifos is a cholinesterase inhibitor, the residual period on the leaves is not long, but the residual period in the soil is longer, and it has a good control effect on underground pests. Sensitivity to tobacco. [0003] Thiamethoxam (thiamethoxam) chemical name: 3-(2-chloro-1,3-thiazol-5-ylmethyl)-5-methyl-1,3,5-oxadiazin-4-ylidene (nitrate Base) amine, the drug is a new type of high-efficiency, low-toxicity broad-spectrum insecticide. It is a second-generation neonicotinoid insecticide, and its mechanism of action is similar to that of the first-generation neonicotinoid insecticides such as imidacloprid, but it has higher activity...
