Abstract

The invention discloses an insecticide combination containing pymetrozine and high-efficacy lambda-cyhalothrin, which is mainly characterized in that the insecticide combination contains active ingredients, i.e. the pymetrozine and the high-efficacy lambda-cyhalothrin, the remaining ingredients are assistants, the weight ratio of the pymetrozine to the high-efficacy lambda-cyhalothrin is 9:1 to 1:9, and the combination is made into microcapsule suspension, microcapsule suspension - suspension or oil suspension. The insecticide combination has the advantages that the insecticide combination can prevent and control various injurious insects, the synergistic effect is obvious, the insecticidal spectrum is expanded and the activities to the injurious insects on rice, vegetables, cotton and fruit trees are high; the insecticide combination has a slow release effect, the pesticide dosage is reduced, the insecticide combination is safe to human beings and livestock, the pesticide damage does not exist and the environmental compatibility is good; and the preparation adhesive force is reinforced, the insecticide combination is resistant to rainwater washing, the efficacy duration is long, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing pymetrozine and lambda-cyhalothrin. Background technique [0002] Pymetrozine chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)-one, molecular formula: C 10 h 11 N 5 O. Pymetrozine belongs to pyridine or triazinone insecticides. It is a brand-new non-biocide insecticide and can be used to control most of the Homoptera pests, especially Aphididae, Whitefly, Leafhopper and Pests of planthoppers, suitable for vegetables, rice, cotton, fruit trees and various field crops. Pymetrozine has contact killing and systemic properties, and can be transported in both xylem and phloem in plants; therefore, it can be used as foliar spray or soil treatment. Thanks to its good transporting properties, new shoots and leaves can also be effectively protected after spraying the stems and leaves. [0003] Lambda-cyhalothrin chemic...
