Mixed insecticide composition containing fipronil

Abstract

The re-compounded pesticide composition includes fipronil in the weight ratio to other component of 0.02-50, and at least one of the following pesticides: lambda-cyhalothrin, fenpropathrin, cycloprothrin, esfenvalerate, etofenprox, etc. It may have functional assistant, diluent or carrier added to compound into oil emulsion, soluble liquid, super low capacity sprayed agent, water emulsion, microemulsion or other preparation forms. It has wide pesticidal spectrum, high activity, low cost, less resistance and other features, and may be applied in preventing and controlling pests of rice, vegetable, cotton, corn, fruit tree, tobacco and other crops.

Description

technical field [0001] The invention relates to a compound insecticidal composition containing fipronil, and the preparation and application technology of various formulations of the composition. In particular, the present invention relates to an insecticidal composition compounded with fipronil and at least one insecticide selected from pyrethroids, organophosphorus, carbamates and pyridines. Background technique [0002] Insecticide resistance has become the focus of attention of the pesticide and plant protection circles in recent years. According to relevant reports, the resistance to pyrethroid insecticides has developed rapidly, among which the resistance of cotton bollworm to fenvalerate has reached 228.2 times, and the resistance to bifenthrin is the lowest, also more than 10 times. Other pesticides have also developed resistance to varying degrees due to years of use. [0003] On the contrary, fipronil, which is still in the stage of popularization and application...
