Insecticidal composition containing sulfoxaflor

Abstract

The invention discloses an insecticidal composition containing sulfoxaflor, comprising A and B components, wherein the active component A is selected from sulfoxaflor and the active component B is selected from any one of the following insecticides: pymetrozine, imidacloprid, acetamiprid, nitenpyram, thiamethoxam, buprofezin, thiacloprid, clothianidin and dinotefuran; and the weight percentage of the active components A to B is: (1-50%): (1-50%). The composition can be used for preventing and treating many insects, has obvious synergy, expands the insecticidal range and has relatively high activity on sucking insects such as plant hopper, aphid, Empoasca pirisuga Matsumura and aleyrodid, and Lepidoptera pests such as plutella xylostella and spodoptera exigua. Furthermore, the composition reduces the usage of the farm chemical and residue of the farm chemical on the crops, alleviates the environment pollution, and has safety on both human and poultry, good environment compatibility; and the insects are difficult to generate drug resistance.

Description

technical field

[0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing sulfoxaflor. Background technique

[0002] Sulfoxaflor, English common name (sulfoxaflor), structural formula: C 10 h 10 f 3 N 3 OS chemical name: [1-[6-(trifluoromethyl)pyridin-3-yl]ethyl]methyl(oxy)-λ4-mercaptocyanamide. Sulfoxaflor is an insecticide of sulfonylimide, which acts on the nervous system of insects, that is, acts on a unique binding site in the choline receptor to exert insecticidal function. It can be absorbed into plants through leaves, stems and roots.

[0003] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. Agriculturally important pests such as Lepidoptera pests are particularly prone to resistance due to their short reproductive cycle, large reproductive capacity, small mobility, and high degree of self-fertilization.
