Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to an emulsion in water containing isazofos and applications thereof. The effective components in the emulsion in water are high-efficient trans-cypermethrin and isazofos, wherein the weight ratio of isazofos to high-efficient trans-cypermethrin is in a range of 5:1 to 1:5. The compounding composition effectively solves the problem of generation of drug resistance of insects, maximally relieves the problem of drug resistance of insects, thus reduces the using amount of pesticide, reduces the pollution to the environment, is accord with the trends of green and environment-friendliness in the future society, and obtains an optimum 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 chlorazophos and its application. Background technique [0002] Chlorazophos [0003] 【CAS No.】42509-80-8 [0004] 【Relative molecular weight or atomic weight】313.7 [0005] 【Density】1.23(20℃) [0006] [Boiling point (°C)] 120°C (32Pa) [0007] 【Vapor pressure (Pa)】7.45mPa(20℃) [0008] Pure product is yellow liquid [0009] 【Dissolution】 [0010] The solubility in water at 20°C is 168mg / L. Solvent dry benzene, chloroform, hexane and methanol [0011] Organophosphorus insecticides and nematicides with contact, stomach toxicity and systemic effects. It can be used as a soil treatment agent, and can also be used for seed treatment or foliar spraying. [0012] However, its effect is also very single, and the risk of resistance after large-scale application is also very high. [0013] Beta-cypermethr...
