Abstract

The present invention relates to a pesticide microemulsion containing bromothalonil and pyraclostrobin, wherein the components in the formula comprise, by weight, 5-35% of bromothalonil, 5-30% of pyraclostrobin, 8-18% of a solvent, 6-12% of a surfactant, 1-5% of a synergist, and the balance of water. According to the present invention, the problems of single prevention and control effect, short lasting period and the like of the applications of pyraclostrobin and bromothalonil in prevention and control of crop downy mildew, anthracnose, leaf spot and other diseases are solved, and the pesticide microemulsion has characteristics of varied prevention and control effect, drug resistance delaying, lasting period prolonging and low cost, is used for prevention and control of a variety of diseases and pests of cucumber, fruit trees, vegetables and other crops, and further has characteristics of significant synergy, low toxicity to humans and animals, and broad insecticide spectrum; and the effective active components bromothalonil and pyraclostrobin belong to the two bactericides having different action mechanisms, such that the conflict can not be generated after the mixing of the two effective active components.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a pesticide microemulsion containing bromothalonil and pyraclostrobin.
