Recompounded pesticide of emamectin benzoate and fipronil

Abstract

The present invention belongs to the field of farm pesticide technology, and is especially one kind of re-compounded pesticide comprising emamectin benzoate in 0.1-10 wt% and fipronil in 0.2-10 wt%. The re-compounded pesticide may be prepared into oil emulsion, aqueous emulsion, wettable powder, soluble liquid, microemulsion and other forms. It has cotoxicity coefficient 106-146, broad pesticidal spectrum, quick acting, high speficity and relatively low cost. It is suitable for preventing and killing pests of rice, cotton, vegetable, fruit tree, etc, and has excellent preventing and killing effect, especially on rice leaf roller, and no untoward reaction on rice growth and development.

Description

Technical field [0001] The invention relates to a compound pesticide, in particular to a compound pesticide which has a certain effect on the rice leaf roller. Specifically, it is a compound pesticide of emamectin benzoate and fipronil. Background technique [0002] Emamectin benzoate (emamectin benzoate) is a new type of antibiotic insecticide and acaricide with high efficiency, broad spectrum and long residual period obtained by chemical semi-synthesis with avermectin as raw material. Its mechanism of action hinders the transmission of information from the motor nerves of pests, leading to paralysis and death. The mode of action is stomach poisoning as the main contact effect, and all of it can effectively penetrate into the epidermal tissue of the applied crops, so it has a long residual effect period, and pests are not easy to develop resistance. It has good control effect on piercing-sucking and chewing mouthparts pests, has high activity on mites, Coleoptera and Homop...
