苯异苄复配除草剂在水稻抛秧田的应用研究

摘要

Application of the herbicide mixture of mefenacet + metolachlor + bensulfuron-methyl in transplanted rice fields by seedling-broadcasting was studied in Saoxing, Zhejiang in 2000. The result showed the mixture at the dosage of 200 g a.i./hm2 has the application characteristics of high effect, broad control spectrum to weeds and high safety to rice. Therefore, it is suitable for the control of Echinochloa crusgalli, Cyperus difformis, Monochoria vaginalis, Rotala indica,Ludwigia prostrata, et al.%苯异苄是一种三元复配的新型稻田除草剂。通过在抛秧田的应用研究表明，33％苯异苄WP具有高效、广谱、安全等特点，每666．7m2用40g对稗草、异型莎草、鸭舌草、节节菜、丁香蓼等稻田主要危害杂草的防效均在90％以上，适宜于在生产上推广应用。
