Insecticidal composition for controlling underground insect

Abstract

The invention relates to an insecticidal composition in the field of pesticide complex formulation. The insecticidal composition comprises effective components of fipronil and lythidathion in a mass ratio of 1-80:80-1, and preferably 1-45:40:1; a total mass of the effective components of fipronil and lythidathion accounts for 1-90% of a total mass of a preparation, and d preferably 1-35%. According to methods in the technical field, the insecticidal composition of the invention can be prepared into a particulate agent, a suspension seed coating agent, a wettable powder seed dressing agent and a suspending agent seed dressing agent; and the insecticidal composition of the invention has high activity on most underground insects.

Description

technical field

[0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition mainly used for controlling underground pests, which is compounded with thiazophos and fipronil as active ingredients. Background technique

[0002] Fipronil, a new type of highly active insecticide of phenylpyrazoles developed by Rhone-Planck Agrochemical Company of France in 1987, chemical name (RS)-5-amino-1-(2,6-dichloro -4-trifluoromethylphenyl)-4-trifluoromethylsulfinylpyrazole-3-carbonitrile. The pesticide was officially registered in the United States in 1996, and was tested and demonstrated on a large scale in China in the late 1990s. It was widely used to prevent and control various agricultural pests on rice, vegetables, cotton, tobacco and other crops. In particular, it shows a very high control effect on pests resistant to pyrethroids, organophosphates, and carbamates.
