Problems solved by technology

[0007] Over the years, the amount of pymetrozine used in the field has gradually increased. At the same time, the problem of resistance to pests has become increasingly serious, resulting in an increase in the amount of pymetrozine used in the field, and an increase in the number of repeated applications. cost of medication
In addition, the high selectivity of pymetrozine leads to a narrow insecticidal spectrum and a relatively single mode of action.
The new insecticide Pyrifluquinazon has high selectivity, strong activity against piercing-sucking pests, environmental protection, and low toxicity. However, judging from the current actual application situation in the field, a single agent of the new insecticide is very effective as soon as it is launched. Yes, the amount of application has increased sharply in a short period of time, making it easy for pests to develop resistance in a short period of time

Abstract

The invention relates to insecticide composition in the field of combination of pesticides. Effective constituents of the insecticide composition comprise novel quinazoline insecticide pyrifluquinazon and pymetrozine, wherein the novel quinazoline insecticide pyrifluquinazon and the pymetrozine are mixed. The weight percentage of the novel quinazoline insecticide pyrifluquinazon and the pymetrozine is 1-90 to 90-1, and the optimal weight percentage is 5-70 to 75-5. The whole quantity percentage of the effective constituents in the insecticide composition is from 1% to 90%, and optimal percentage is from 6% to 70%. The balance is auxiliary elements permitted and accepted in pesticides. Emulsion in water, missible oil, suspending agent, wettable powder and water dispersible granule can be prepared by using a known method. The quinazoline insecticide is mainly used for preventing and curing the pests including aphididae, aleyrodidae, cicadellidae, and delphacidae.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a dual compound insecticidal composition with novel quinoline insecticides pyrifluquinazon and pymetrozine as active ingredients. Background technique [0002] Pyrifluquinazon is a new type of quinazoline insecticide newly developed by Japan Pesticide Company. Its mechanism of action is very novel. Its mechanism of action is to prevent pests from eating until they die slowly. It is highly selective and suitable for integrated pest control. Target biosafety, mainly used for the control of piercing-sucking mouthparts pests such as whitefly, broad bean aphid, aphid and scale insect on vegetables, fruit trees and tea, with excellent control effect. The chemical structural formula of novel quinazoline insecticide Pyrifluquinazon is: [0003] [0004] Pymetrozine, alias: pyrazinone, English name: pymetrozine, molecular formula: C 10 h 11 N 50 , chemical name: 4,5-d...
