摘　　要：研究了20%苄嘧磺隆.莎稗磷可湿性粉剂对水稻移栽田杂草的控制效果和对水稻产量的影响,结果表明:该药剂对水稻移栽田的稗草、异型莎草、鸭舌草、碎米莎草等具有良好的防除效果,有效成分用量为300～660 g/hm2的处理在施药60 d后的综合密度防效和综合鲜重防效分别为92.52%～99.59%、92.03%～99.55%,显著优于10%苄嘧磺隆WP和人工除草的防效,水稻增产效果显著,比未施药(CK)的增产22.39%～30.04%,具有良好的推广前景。The wettable powder of 20% Bensulfuron - methyl · Anilofos was used to study its control effects against weeds in transplanted rice field and its effect on rice yield. The results indicated that the wettable powder of 20% Bensulfuron - methyl · Anilofos had good control effects on Echinochloa crusgalli （ L. ） Beauv, Cyperus difformi· L., Monochoria vaginalis （ Burm. F. ） and Cyperus iria L. in transplanted rice field. The overall density control effect and fresh - weight control effect of applying 300 660 g/hm2 Bensulfuron - methyl · Anilofos were 92.52% - 99.59% and 92.03% - 99.55% respectively on the 60th day after spraying, which were significantly higher than those of wettable powder of 10% Bensulfuron and artificial weeding. In comparison with the control （ not applying herbicides）, applying 20% Bensulfuron - methyl · Anilofos significantly increased the yield of rice by 22.39% - 30.04%. So this mixed herbicide had good application prospects in transplanted rice field.
