Abstract

The invention belongs to the technical field of pesticide compound and in particular to an EM (Emulation in Water) for preventing and curing of notodontid moths on poplars. The compound comprises effective components of bifenthrin and BPMC (Sec-butyl Phenyl-N-methyl Carbamate), wherein the ratio by weight of the BPMC to the bifenthrin is 1:1 to 1:10. The compound can solve problems caused by pest resistance effectively and alleviate the problem of present drug resistance of pests at the greatest extent, therefore, the use amount of the pesticide is reduced and the effect on environment is relieved, the EM is in consistency with a green environmental protection trend of the future society, moreover the compound provided by the invention has an optimal crop protection effect.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and in particular relates to a water emulsion for preventing and treating the poplar boat moth. Background technique [0002] Zhong Dingwei [0003] English name: Fenobucarb [0004] CAS number: 3766-81-2 [0005] Molecular formula: C 12 h 17 NO 2 [0006] Molecular weight: 207.27 [0007] EINECS number: 223-188-8 [0008] Related categories: Insecticide (mite) agent; [0009] Mol file: 3766-81-2.mol [0010] Features Zhongdingwei has a strong contact killing effect, and has certain stomach poisoning, fumigation and ovicidal effects, and the action is fast, but the residual effect is short. [0011] However, its effect is also very single, and the risk of resistance after large-scale application is also very high. [0012] Bifenthrin [0013] Moderately toxic to humans and animals, highly toxic to fish. The acute oral toxicity LD50 to rats is 54.5mg / kg...
