Abstract

The invention relates to an insecticidal composition containing pymetrozine, in particular to an insecticidal composition containing pymetrozine and bifenthrin. The insecticidal composition is mainly characterized by containing 5 to 75 percent of pymetrozine, 0.5 to 40 percent of bifenthrin and the balance of auxiliary agent and other excipient; and the insecticidal composition is prepared into wettable powder, water dispersible granules, suspending agent and emulsion. The insecticidal composition is used for preventing and controlling aphids, white flies and plant hoppers on fruit trees, cash crops and vegetables.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition of pymetrozine and bifenthrin, which is used for preventing and controlling pests on fruit trees, economic crops and vegetables. Background technique [0002] Pymetrozine, English name: (pymetrozine), molecular formula: C 10 h 11 N 5 O, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)-one, [0003] Its structural formula is: [0004] [0005] Pymetrozine is a high-efficiency novel insecticide with high selectivity to piercing-sucking mouthparts pests, mainly used for the control of whitefly, thrips, aphids, whitefly, leafhopper, rice planthopper and other pests . It is widely used to control pests such as aphids, planthoppers and whitefly on crop fields, vegetable fields, ornamental plants, and fruit trees. [0006] Bifenthrin belongs to the class of pyrethroid insecticides. Its main mode of action is...
