Problems solved by technology

[0004] From the perspective of current agricultural production, mole crickets, grubs, dayworms, cutworms, root maggots, root stinkbugs, root aphids, pseudo-crickets, crickets, root scales, root leaf beetles, root beetles, root weevils and termites, etc. The damage to crops by underground pests is relatively serious. For a long time, organophosphorus pesticides have been the main method of prevention and control. many
In addition, the above-mentioned thiazophos has a relatively high selectivity to pests, and the actual application of organophosphorus pesticides has been for a long time, and the pests have developed a certain resistance to it, and the control effect has declined.
The separate application of the two single doses cannot meet the requirements of agricultural production, the application cost is high, the number of repeated medications is large, the residue is large, and it is harmful to the environment

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. [0003] The chemical name of thiazole phosphorus (RS)-...
