Abstract

The invention discloses a dinotefuran dispersible oil suspension agent. The dinotefuran dispersible oil suspension agent is prepared from 20-30% of dinotefuran, 4-6% of polyoxyethylene octylphenol ether, 4-6% of calcium dodecyl benzene sulfonate, 4-6% of phenethyl phenylpropyl phenol polyoxyethylene ether, 0.8-1.2% of organobentonite, 0.8-1.2% of white carbon black, 0.1-0.5% of citric acid, 0.1-0.5% of dihydrogenated tallow phthalic acid amide, 0.1-0.5% of tris(2,4-di-tert-butyl-pheny)phosphite, 0.1-0.5% of 2-n-octyl-4-isothiazolin-3-one, 0.1-0.5% of HT-508 organosilicone, 18-22% of soybean oil and the balance methyl oleate. The dinotefuran dispersible oil suspension agent is stable in performance, high in adhesion, good in spreading performance and high in rain wash resistance, has an obvious synergistic effect on target matter and contains no synergist, a medium can be degraded, dust is avoided in the production and use process, pollution is not likely to be caused to the environment and the human, the pesticide effect of dinotefuran can be fully exerted, the dose can be reduced, cost can be reduced, development of the resistance of pests to dinotefuran can be retarded, and the dinotefuran dispersible oil suspension agent has obvious economic and social benefits and good development prospects.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation processing, and relates to a preparation method of dinotefuran dispersible oil suspension.
