Abstract

The invention belongs to the technical field of pesticide compounding and particularly relates to fenobucarb-containing water dispersible granules and an application, wherein the weight ratio of tebufenozide to fenobucarb is (15:1)-(1:5). Compared with a single dose, the fenobucarb-containing water dispersible granules delay the generation of pesticide resistance of pests, enlarge the control spectrum of effective activity, improve the effect obviously to reduce the consumption of the pesticide, and reduce the degree of influence to the environment and the pesticide residue while reducing the pesticide use cost of farmers.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water-dispersible granule containing secbucarb and its application. Background technique [0002] Zhong Ding Wei [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. However, its effect is also very single, and the risk of resistance after large-scale application is also very high. [0011] tebufenozide [0012] English common name tebufenozide [0013] Chemical name N-tert-butyl-N-(4-ethylbenzoyl)-3,5-dimethylbenzoylhydrazid...
