经过室内配方筛选及田间小区对比试验,初步明确41%苯噻酰·吡可湿性粉剂组分配比和杀草谱,对水稻田常发生的稗草、异型莎草、牛毛毡、雨久花、鸭舌草、野慈菇、泽泻、萤蔺、眼子菜等禾本科、阔叶及莎草科杂草有特效,综和防效在85%以上。在单子叶杂草较多的田块使用量(有效成分)为615g/hm2,否则492g/hm2即可,施药时期应掌握在水稻返青后的杂草萌动期,可混拌过筛细沙、细土或化肥均匀撒施。
Through the screening of indoor formula and the field plot comparative test, the ratio of 41% phenylthionopyrazol WP and the herbicide-killing spectrum were initially determined, Monochamus, wild arrowhead mushrooms, Alisma, Ying Lin, Ziziphus and other grass, broadleaf and sedge weeds have special effects, comprehensive and effective control in more than 85%. In monocotyledonous weeds more field use (active ingredient) is 615g / hm2, or 492g / hm2 can be, the application period should master the weed germination period after the greening of rice, can be mixed with sift sand , Fine soil or fertilizer spread evenly.
