摘　　要：6%五氟磺草胺·氰氟草酯油悬浮剂是陶氏益农公司开发的直播田新型除草剂。为明确该药剂对直播水稻田杂草的防除效果、对水稻的安全性及对后茬作物的影响,进行田间小区试验。结果表明:6%五氟磺草胺·氰氟草酯油悬浮剂对水稻田禾本科杂草、部分阔叶杂草及莎草防效优良,对直播水稻安全,增产效果明显;6%五氟磺草胺·氰氟草酯油悬浮剂对水稻田后茬作物小麦、油菜、萝卜的安全性好。因此,6%五氟磺草胺·氰氟草酯油悬浮剂在水稻直播稻区有很好的推广应用前景。6%Penoxsulam·cyhalofop-butyl OD is a new herbicede of Dow AgroSciences for weed control in direct seeding rice fields. The paper studied the weed controlling effect and safety on rice and influence of the following crops on 6%penoxsulam·cyhalofop-butyl with the field experiment in direct rice fields. The results indicated that the controlling effect of 6%penoxsulam·cyhalofop-butyl OD was high eficacy and long efective duration on some gramineaous, broadleaf and cyoeraceae weeds. Penoxsulam·cyhalofop-butyl was safety to direct seeding rice and raise production of rice. Experiment of security evaluating showed that 6%penoxsulam· cyhalofop-butyl OD was safety to mostly following crops （wheat, oilseed rape and radish） too. So 6% penoxsulam·cyhalofop-butyl OD should be extensively application in direct seeding rice area.
