NOVELTY - Flubendiamide and methoxyfenozide-containing nano-suspension agent comprises 1-25 wt.% flubendiamide, 1-25 wt.% methoxyfenozide, 0.1-10 wt.% nano-carrier, 0.1-20 wt.% solvent, 0.2-10 wt.% wetting and dispersing agent, 0.1-0.25 wt.% thickener, 0.1-0.4 wt.% defoamer, 0.01-0.3 wt.% preservative, 0.5-10 wt.% anti-freezing agent, and deionized water (balance amount). The active ingredients are flubendiamide, and methoxyfenozide. USE - The flubendiamide and methoxyfenozide-containing nano-suspension agent is useful in field of pesticide preparation. ADVANTAGE - The suspension agent: has high utilization rate, and long duration; is easy to use and environment-friendly. The method: utilizes nano-materials to load efficient ingredients of the pesticide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing flubendiamide and methoxyfenozide-containing nano-suspension agent, comprising (i) mixing flubendiamide, methoxyfenozide and solvent, heating and stirring until dissolve flubendiamide, methoxyfenozide, then adding nano-carrier, mixing, and loading the active ingredients into nano-carrier to form mixture, and (ii) desolventizing obtained mixture to obtain adsorbent particles, coarsely mixing adsorbent particles with wetting and dispersing agent and deionized water, then enteingr the sand mill for ultra-fine grinding and pulverizing until the D90 (the particle size of 90% of the particles) is less than 500 nm, grinding, pumped into high-speed shearing machine, then adding deionized water with thickener, defoamer, preservative, and anti-freezing agent until dissolve, and performing high-speed shearing to obtain final product.
