Abstract

The invention provides a chlorpyrifos-methyl and benzoylurea pesticide containing composition, which contains chlorpyrifos-methyl and a benzoylurea pesticide, wherein the benzoylurea pesticide is one or more selected from novaluron, teflubenzuron, diflubenzuron, triflumuron, hexaflumuron, flufenoxuron, buprofezin, flucycloxuron, chlorbenzuron and lufenuron; the mass ratio of the chlorpyrifos-methyl to the benzoylurea pesticide is (1 to 80) to (80 to 1), preferably (1 to 40) to (40 to 1), more preferably (1 to 20) to (20 to 1) and most preferably (1 to 10) to (10 to 1). The composition has remarkable synergistic effects, the dosage can be reduced, and the drug cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a composition of insecticidal active compounds, in particular to a composition containing chlorpyrifos-methyl and benzoylurea insecticides, as well as its preparation and application. Background technique [0002] Chlorpyrifos-methyl (chlorpyrifos-methyl) is a broad-spectrum organophosphate insecticide, which is effective through contact killing, stomach poisoning and fumigation, and has no systemic properties. It is used to control pests in stored grains and various foliage crops. It can also be used to control adult mosquitoes, flies, aquatic larvae and sanitary pests. [0003] [0004] Benzoylurea insecticides, the main components are benzoylurea compounds, which are a class of insect growth regulators that can inhibit the synthesis of chitin in target pests and cause their death or sterility. They are known as the third generation Insecticides or new insect control agents. Due t...
