Problems solved by technology

For a long time, the control of rice planthoppers has mainly relied on imidacloprid, dichlorvos and other pesticides. Among them, imidacloprid is highly resistant, and dichlorvos has a short duration of action, and the pesticides that are better for control, such as fipronil, chlorpyrifos, and pymetrozine, are expensive or expensive. poor persistence

Abstract

The present invention discloses one kind of pesticide composition for preventing and killing plant hopper. The pesticide composition consists of pymetrozine 0.5-25 wt%, buprofezin 0.5-25 wt%, assistant 5-25 wt%, and stuffing 25- 94 wt%. The stuffing may be bentonite, fine particle calcium carbonate, kaolin, silica white or water; and the assistant may be starch, PVA, lignin sulfonate, etc. The pesticide composition of the present invention has the advantages of fast acting, lasting action, less influence on environment and low cost.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, and in particular relates to an insecticidal composition for controlling rice planthopper. Background technique [0002] The annual planting area of ​​rice in China is about 27 million hectares. Rice planthoppers are the main pests of rice, including the brown planthopper Nilaparvata lugens Stal and the brown planthopper Laodelphax striatellus Fallen, which suck rice juice through piercing-sucking mouthparts and spread viral diseases. In recent years, rice planthoppers have been rampant in major rice producing areas, causing huge losses in rice production. For a long time, the control of rice planthoppers has mainly relied on imidacloprid, dichlorvos and other pesticides. Among them, imidacloprid is highly resistant, and dichlorvos has a short duration of action, and the pesticides that are better for control, such as fipronil, chlorpyrifos, and pymetrozine, are expensive or expensi...
