Insecticidal combination containing o-phenylendiamine insecticide and sulfoxaflor

Abstract

The invention relates to an insecticidal combination containing o-phenylendiamine insecticide and sulfoxaflor. The insecticidal combination is characterized in that active components of the insecticidal combination are o-phenylendiamine insecticide A and sulfoxaflor, and the remaining are auxiliary components for preparing pesticide formulations. The weight part ratio of the active component o-phenylendiamine insecticide A to sulfoxaflor is (1-30):(30-1). The pesticide formulations capable of being prepared from the insecticidal combination comprise wettable powder, suspending agent, soluble liquid, emulsion in water and water dispersible granules. The total weight parts of the active components o-phenylendiamine insecticide A and sulfoxaflor in the pesticide formulations account for 5-40% the total weight parts of the formulations. The two effective active components o-phenylendiamine insecticide A and sulfoxaflor in the combination have an obvious synergistic effect, the insecticidal spectrum is expanded, the pesticide amount is reduced, the control effect is improved, residue is less, the duration is long, and the insecticidal combination is favorable for delaying pesticide resistance of pests and environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing o-phenylenediamine insecticides and sulfoxaflor. Background technique [0002] The chemical structural formula of o-phenylenediamine insecticide A is as follows: [0003] , [0004] The insecticide is a new insecticide compound announced by Syngenta, and its mechanism of action is currently disclosed as a ryanodine receptor agent. There are no more experimental reports or publications, and there is no disclosure of field tests in the field of compounding. [0005] Sulfoxaflor, its chemical name: [1-6-(trifluoromethyl)pyridin-3-yl]ethyl]-λ4-mercaptocyanamide; molecular formula: C 10 h 10 f 3 N 3 OS, the structural formula is: [0006] [0007] Sulfoxaflor is a sulfonylimide insecticide that acts on a unique binding site in the choline receptor to exert insecticidal function. It can be absorbed into plants through lea...

AI Technical Summary

Problems solved by technology

[0008] Long-term use of a single insecticide will easily lead to insect resistance and increase the amount of pesticide used, leading to adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy, and the field of action is relati
