Abstract

The invention belongs to the technical field of pesticide compound, particularly relates to a cartap contained EW (emulsion in water) and application. Effective ingredients of the composition are bifenthrin and cartap, wherein the weight ratio of cartap to bifenthrin is (1:1) to (1:10). The compound combination effectively resists the problem about the production of pest resistance, thereby mitigating the conventional resistance to drugs of pests to the largest extent; less use of pesticide reduces influence on the environment, and the trend of green environmental protection in future society is conformed; the composition provided by the invention achieves the optimal crop protection effect.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to an aqueous emulsion containing cartap and its application. Background technique [0002] cartap [0003] Molecular formula: C 7 h 15 N 3 o 2 S 2 ·HCl [0004] Molecular mass: 273.81 [0005] S,S'-[2-(Dimethylamino)-1,3-propanediyl]thiocarbamate hydrochloride [0006] Property description: white powder, melting point 179-181°C. Soluble in water, slightly soluble in methanol and ethanol, insoluble in acetone, ether, ethyl acetate, chloroform, benzene and other organic solvents. The pH of 1% aqueous solution is 3-4. Stable under normal temperature and acidic conditions, unstable under alkaline conditions. [0007] Qianzai has a strong stomach poisoning effect, and also has contact killing, certain food refusal, and egg killing effects. Knock down pests quickly, have a long residual effect period, and have a broad spectrum of ins...
