摘  要:
To get the stable product of the mesotrione · isoxaflutole · atrazine 27% SC, we had filtrated the different formulation adjuvants including the wetting and dispersing agent, stabilizing agent, thickening agent, antifreeze,antifoaming agent and preservatives, which were added into the three raw materials of mesotrione, isoxaflutole and atrazine, and then sheared and grinded for 2 hours, and final formulation formula were obtained. Experiments results shown that the mesotrione·isoxaflutole·atrazine 27% SC had stable appearance, no caking, low dialysis ratio of water,and the three kinds of active ingredients had high suspending rate, good fluidity, and the decomposition rate in hot storage was less than 5%, and the suspending rate can be more than 95%. Meanwhile, the control effects of the product were significantly better than the similar products in the market, and it has a value for promotion and application.
