Description
Technical Field
The invention relates to a herbicide composition for paddy fields, in particular to a liquid herbicide preparation of ethyl 2- (2-chloro-5- (3-chloro-5-trifluoromethylpyridine-2-yl) -N-methylbenzenesulfonamide) acetate and a using method thereof, belonging to the technical field of agricultural herbicides.
Background
Rice is an important grain crop, and the planting area of the rice is wide. The ethyl 2- (2-chloro-5- (3-chloro-5-trifluoromethylpyridin-2-yl) -N-methylbenzenesulfonamide) acetate (patent numbers: CN 102464611A, CN 103003240A and WO 2012059050A 1) has extremely high herbicidal activity, and can effectively control weeds such as cockspur grass, piemarker, snakehead, green bristlegrass, zinnia elegans, xanthium sibiricum, monochoria japonica, arrowhead and the like in paddy fields by stem and leaf spraying or broadcasting.
Although ethyl 2- (2-chloro-5- (3-chloro-5-trifluoromethylpyridin-2-yl) -N-methylbenzenesulfonamide) acetate can be used as a spray solution by first dissolving it with an organic solvent (such as acetone) (the content of acetone in the total solution is not more than 10%), and then preparing a solution with a desired concentration from 0.1% Tween 80 in water, there are significant drawbacks: on one hand, the prior preparation is troublesome to apply, the use amount of the organic solvent is large, the environmental impact is large, and the cost is high; on the other hand, the prepared solution needs to be used immediately, and the effective components are easy to separate out after being placed for a long time and cannot be used next time. Especially, the main problem in the herbicide industry at present is how to select an auxiliary agent system suitable for active ingredients, control the dynamic surface tension and the droplet particle size of the sprayed liquid medicine, ensure that the liquid medicine has small drift, slow evaporation, good spreading, wetting and adhesion on a target and long retention time, thereby improving the utilization rate of the pesticide and simultaneously reducing the problem of phytotoxicity caused by drift. In addition, the biological activity of the herbicide liquid preparation prepared by the conventional method is usually lower or slightly lower than that of the original drug.
