Insecticidal ring nano dry suspension, preparation method, application and pest control method

Abstract

The application discloses a nanometer dry suspension of insecticidal ring, a preparation method, application and a pest control method, and belongs to the technical field of pesticide preparations. The nanometer dry suspension of insecticidal ring comprises, in percentage by mass, 50-60% of a pesticide active ingredient, 13-20% of a traditional wetting dispersant, 2-4% of an ultra-high-efficiency wetting dispersant, 0.5-1% of a disintegration aid, 2-4% of a stabilizer, 1-3% of an antifoaming agent and a remainder of a filler; the pesticide active ingredient comprises insecticidal ring; and the ultra-high-efficiency wetting dispersant comprises HLB-F031. The nanometer dry suspension of insecticidal ring effectively improves the problems of easy water solubility and poor stability of insecticidal ring by adopting a new auxiliary system. The preparation method is optimized, the problems of decomposition and caking of insecticidal ring due to long-time stay in a high-temperature aqueous phase environment are relieved, and the particle size of the pesticide can be stably controlled to be less than 800 nm, and the drug efficacy is significantly improved. 90 ​
