选用96%金都尔乳油、90%禾耐斯乳油、33%施田补乳油和25%宝成水分散粒剂4种不同除草剂进行了防效比较试验以及对甘薯的影响研究。结果表明：喷施96%金都尔乳油1200 mL/hm2杂草防除效果最优，总株防效和鲜重防效均达到了87%以上，且藤蔓鲜重和鲜薯产量均比空白对照增产，增产幅度分别达到了54.02%和29.32%，干物率和商品率与对照差异不显著。从杂草防效及对甘薯地上部藤蔓、鲜薯产量、干物率和商品率的影响综合考虑，使用96%金都尔乳油1200 mL/hm2在甘薯田杂草防除效果最好。

An experiment was carried out to compare the weed control efficacy and effect on sweet potato,by using four kinds of herbicides of 96%s-metolachlor EC,90%acetochlor EC,33%pendimethalin,25%rimsulfuron DF in sweet potato fields.The best herbicide was 96%s-metolachlor EC 1 200 mL/hm2,which the total control efficacy for each plant and blank control effect on fresh weight reached respectively more than 87%. Compared with the CK,the yields of fresh vines and fresh root of 96%s-metolachlor EC 1 200 mL/hm2 increased respectively more than 54.02%and 29.32%.Then there were no significant differences with CK on the dry matter content and commodity rate.Considering the comprehensive factors of weed control effects,aboveground vines,fresh root yield,dry matter content and commodity rate,the optimum weeds control method for sweet potato field was using 96%s-metolachlor EC 1 200 mL/hm2.
