Abstract

The invention belongs to the technical field of pesticides, and relates to a suspending agent containing pymetrozine and bifenazate and used for prevention and treatment of insect pests with piercing-sucking mouthparts and harmful mites. The suspending agent comprises the raw materials by the weight percentage: 1-45% of pymetrozine, 1-20% of bifenazate, 1-4% of an emulsifier, 1-5% of a dispersant, 0.1-1.5% of a thickener, 0.01-1% of a defoaming agent, 3-9% of an antifreezing agent, 0.1-4% of a stabilizer, and the balance deionized water. The suspending agent containing pymetrozine and bifenazate can be used for prevention and treatment of aphids, leafhoppers, trialeurodes vaporariorum and other insect pests with piercing-sucking mouthparts on field crops, fruit trees and vegetables as well as tetranychus urticae, tetranychus truncatus and other harmful mites, effectively expands insecticidal spectra, can kill both the insect pests and the mites, besides, also is beneficial for lowering the use amount of drugs, decreases the number of times of spraying the drugs, and delays generation of drug resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a suspending agent containing pymetrozine and bifenazate, which is used for preventing and treating piercing-sucking mouthpart pests and harmful mites. Background technique [0002] Pymetrozine belongs to pyridine or triazinone insecticides and is a brand-new non-biocide insecticide. The product has a contact effect on pests and is effective against piercing and sucking mouthparts pests of various crops, such as aphids and leafhoppers. , planthopper, whitefly, etc. all showed excellent control effect. Since pymetrozine has good systemic activity and can conduct bidirectionally up and down in the plant body, the whole plant and even the newly grown branches and leaves can be effectively protected after spraying the stems and leaves. Its chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)-one, and its molecular structure is as follows: [0003] [000...
