Abstract

The invention discloses an insecticidal composition containing thiamethoxam and application thereof. Active components in the insecticidal composition comprise the thiamethoxam and epoxy thiacloprid at the weight ratio ranging from (1 to 20) to (10 to 1); furthermore, the preferable weight ratio ranges from (1 to 10) to (5 to 1). The insecticidal composition disclosed by the invention is prepared into any preparation suitable for agricultural production through a known method and auxiliary components and the preparations include, but not limited to any one of missible oil, wettable powder, water dispersible granules, a suspending agent, emulsion in water, micro-emulsion and the like. According to the insecticidal composition disclosed by the invention, the active components have a synergetic effect in the ranges, the dosage of the active components of pesticide can be reduced and the prevention and control effect is improved; the insecticidal composition is especially suitable for preventing and controlling rice planthoppers, aphids and the like.

Description

technical field [0001] The invention belongs to the field of pesticide insecticidal compositions, and in particular relates to an insecticidal composition comprising thiamethoxam and epoxycloprid and its application for controlling crop pests. Background technique [0002] Rice planthoppers belong to the family Delphacidae of the order Homoptera, and are commonly known as midges, fire midges, and rat gnats. Harm rice and other crops by sucking plant juice. There are mainly three kinds of planthoppers that damage rice in my country: brown planthopper (Nilaparvata lugens Stal), white-backed planthopper (Sogatella furcifera (Horvath)) and white-backed planthopper (Laodelphax striatellus Fallén). Lice followed. The current main means of controlling rice planthoppers is to use chemical insecticides. The long-term and large-scale use of chemical insecticides will lead to the emergence of drug resistance. Therefore, it is necessary to continuously adjust the varieties of pesticide...
