NOVELTY - Dispersible oil suspension agent containing nicosulfuron and atrazine comprises 30-50 pts. wt. nicosulfuron, 150-250 pts. wt. atrazine, 75-100 pts. wt. calcium dodecyl benzene sulfonate, 30-50 pts. wt. tristyrylphenol polyoxyethylene ether, 15-25 pts. wt. alkylphenol polyoxyethylene ether, 10-20 pts. wt. thickening agent, 500-700 pts. wt. methyl oleate and 40-80 pts. wt. adsorbent, where the adsorbent comprises graphene and acrylamide in a weight ratio of (1-5):1. USE - As dispersible oil suspension agent. ADVANTAGE - The dispersible oil suspension agent is difficult to be washed into the deep soil layer by rainwater, and improves the durability of the drug effect of the dispersible oil suspension agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the dispersible oil suspension agent containing nicosulfuron and atrazine involving (S1) adding calcium dodecylbenzene sulfonate, tristyrylphenol polyoxyethylene ether, and alkylphenol polyoxyethylene ether to methyl oleate and stirring uniformly to obtain a base liquid, (S2) adding atrazine, nicosulfuron and graphene to the base liquid and stirring uniformly to obtain a premix, (S3) adding acrylamide, EDTA, organic bentonite, methyl cellulose, chitin and sodium citrate to the premix and stirring uniformly to obtain a mixture and (S4) grinding the mixture and stirring uniformly after secondary grinding to obtain the dispersible oil suspension agent.
