Abstract
The invention relates to a pesticide, especially involving a pesticide compound composed of Thiamethoxam phoxim. The invention can be made into creaming agent, and suspend agent or micro-emulsion. The invention has the merits of high efficiency, low toxicity, strong absorption, special control effects on crops soil pests, and can be used as alternative agent of pesticide of high toxic, high residues for controlling soil pests in public existing technology. Seed dressing or watering with the product not only has good control effects for soil pests, but also has better effects for sucking pests on ground, such as aphids of various crops, whiteflies, thrips, beetles and other pests.
Description
technical field [0001] The invention relates to a pesticide, in particular to an insecticide composition composed of thiamethoxam·phoxim. technical background [0002] Phoxim: The chemical name is O, O-diethyl-O-(-cyanophenylimino) phosphorothioate, and the molecular formula is C 12 h 15 N 2 o 3 PS, has the characteristics of contact killing, quick effect, and a certain residual effect period. Seed dressing or irrigation can prevent and control a variety of underground pests of crops. [0003] Thiamethoxam: 3-(2-chloro-5-thiazolylmethyl)-5-methyl-N-nitro-4H-1,3,5-tetrahydrooxadiazine-4-imine, molecular formula for C 8 h 10 CIN 5 o 3 S, is a new, high-efficiency, low-toxic broad-spectrum insecticide, with systemic, stomach poisoning and contact killing effects, against sucking pests such as: aphids, leafhoppers, planthoppers, thrips, whitefly, beetles And other resistant strains of pests have special effects. In the prior art, phoxim and thiamethoxam are mainly used...
