Abstract

The invention relates to the field of pesticides, and discloses a pesticidal composition. The pesticidal composition comprises active components, i.e., thiamethoxam and phoxim, wherein the mass ratioof thiamethoxam to phoxim is 2: 1 to 1: 20. The pesticidal composition provided by the invention can be prepared into granules. The pesticidal composition has the following advantages: through compounding of two active components, significant synergistic effect is obtained; the usage amount of the pesticidal composition can be reduced; the insecticidal spectrum is expanded; the speed of killing pests is improved; the duration time of killing the pests is prolonged; the resistance is delayed; and the safety to crops and the environment is realized.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticidal composition containing thiamethoxam and phoxim, which is used for controlling crop pests. Background technique [0002] Thiamethoxam: English name: thiamethoxam, chemical name: (EZ)-3-(2-chloro-1,3-thiazolyl-5methyl)-5-methyl-N-nitro-1,3,5 -oxadiazine-4-imine, molecular formula: C 8 h 10 ClN 5 o 3 S. Thiamethoxam is a second-generation nicotinic high-efficiency and low-toxicity insecticide with a new structure, which can selectively inhibit the nicotinic acid acetylcholinesterase receptor in the insect central nervous system, thereby blocking the normal conduction of the insect central nervous system, causing Pests die when paralyzed. Not only has contact killing, stomach poisoning, and systemic activity, but also has higher activity, better safety, wider insecticidal spectrum, fast action speed, and long-lasting effect. It has high activity against Coleop...
