Abstract
The invention discloses a chlorpyrifos-containing insect disinfestation composition, which is mainly characterized by comprising an effective active component chlorpyrifos and an effective component B, wherein the effective component B is selected from thiamethoxam, clothianidin and thiacloprid, a weight ratio of the chlorpyrifos to the effective component B is 20:1-1:5, and the composition can be prepared into a microcapsule suspension and a microcapsule suspension-suspending agent. The composition can be provided for prevention and control of a plurality of insect pests, has characteristics of significant synergy effect and prevention and control spectrum expanding, provides high activities for pests on grassy crops, tea trees, vegetables, cotton and fruit trees, and further has advantages of slow release, pesticide amount reduction, safety on human and animals, no pesticide injury, good environment compatibility, strong preparation adhesion, rain erosion resistance, long lasting period and the like.
Description
technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticidal 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, thiamethoxam is a new type of broad-spectrum insecticide with high efficiency and low toxicity. 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...
