The invention discloses a paddy herbicide and a manufacturing method thereof, in particular to the suspension agent and its manufacturing method. Btmpa bensulfuron methyl dry, the raw material of the invention consists of mefenacet and bensulfuron methyl TC, TC water, dispersant, wetting agent, penetrating agent, thickening agent and additives; its manufacturing process comprises the following steps: mixing liquid wet milling, spray drying, sieving, packaging. Mefenacet. Bensulfuron methyl dry suspending agent in technology by repeated sanding treatment, the single molecule diameter less than 5 microns, the suspension rate is greater than 90%, dispersed in water faster than the original WP increased by more than 80%, than the original effect of WP increased by more than 20%. The dry suspending agent can poison indigenous or spray method used for transplanting rice field (North), rice seedling (South), annual and perennial weed control section, it has the advantages of low toxicity, high efficiency, less dosage, low cost, wide weed control spectrum, no pollution to the environment and convenient use etc..
【技术实现步骤摘要】
【国外来华专利技术】
本专利技术公开了一种水田除草剂及其制造方法,具体的说是。
技术介绍
目前,水田中常用的除草剂苯噻草胺和苄嘧磺隆混配均为可湿性粉剂,其活性组分由苯噻草胺和苄嘧磺隆组成,苯噻草胺和苄嘧磺隆含量差别较大,总含量从18%~68%不等,农业部药检所登记有60多种。制造方法主要采用V型混合机粗混,气流粉碎机粉碎,粉碎后的粒度为44μm,在用无重力混合机精混,包装。其缺点是颗粒粗,悬浮率低,在水中分散速度慢,药效低,粉尘易飞扬,使用和生产过程中对环境污染大。
