Problems solved by technology

Although it has a long duration, Buprofezin is an insecticide that inhibits the growth and development of insects. Its effect is slow and has no lethal effect on adults, so it cannot quickly control the damage.
[0008] The compositions containing buprofezin currently registered and in use in China mainly include: buprofezin and isoprocarb, buprofezin and monosultap, buprofezin and triazophos, buprofezin and imidacloprid, buprofezin No one has reported the compounding and application of buprofezin and nitenpyram with pyridaben, buprofezin and beta-cypermethrin, etc.

Abstract

The invention relates to a desinsection composite and application thereof. The effective components are Nitenpyram and Buprofezin; the weight portion ratio of the Nitenpyram to the Buprofezin is 5:1-1:20. The desinsection composite can be processed into any preparation formulation acceptable to pesticide application; the preferable preparation formulation is wettable powder, aqueous emulsion, missible oil, microemulsion, water dispersible granule or troche, and suspending agent. The composite is used for controlling pests on plants, especially the homoptera pests like plant hopper, leafhopper, white fly, and the like.

Description

technical field [0001] The present invention relates to a pesticide composition and its application, in particular to a composition with nitenpyram and buprofezin as active ingredients, which is used to prevent and control agricultural pests, especially suitable for controlling planthoppers, whiteflies, aphids and other pests , and is especially suitable for controlling Homoptera pests such as rice planthoppers, whiteflies, and aphids that have developed resistance. Background technique [0002] In agricultural production, chemical control is the main effective means of controlling pests. The most likely problem to arise from chemical pest control is the development of pest resistance. Pests that are prone to resistance are usually those with large reproduction numbers and obvious overlapping generations, such as planthoppers, whiteflies, and aphids. [0003] Rice planthopper is one of the three major pests of rice, which can migrate long distances and spread rice virus di...
