通过田间试验比较了60 g/L五氟磺草胺·氰氟草酯油悬浮剂、2．5％五氟磺草胺油悬浮剂、10％氰氟草酯乳油、10％双草醚悬浮剂、9％嘧啶肟草醚·氰氟草酯微乳剂、5％嘧啶肟草醚乳油、10％氟吡磺隆水分散粒剂、10％唑酰草胺乳油8种除草剂对水直播稻田杂草的防除效果及对水稻的安全性。结果表明：8种除草剂中，60 g/L五氟磺草胺·氰氟草酯油悬浮剂、9％嘧啶肟草醚·氰氟草酯微乳剂、2．5％五氟磺草胺油悬浮剂、10％双草醚悬浮剂对杂草均表现出优良的防效，杀草谱广且安全性好，可作为防除直播稻田杂草的主要药剂。10％唑酰草胺乳油、10％氰氟草酯乳油仅能有效控制直播田禾本科杂草。5％嘧啶肟草醚乳油、10％氟吡磺隆水分散粒剂仅能控制直播田阔叶杂草和莎草科杂草，对禾本科杂草的防效不理想。因此，60 g/L五氟磺草胺·氰氟草酯油悬浮剂、9％嘧啶肟草醚·氰氟草酯微乳剂、2．5％五氟磺草胺油悬浮剂、10％双草醚悬浮剂4种除草剂在我国的直播稻区有很好的推广应用前景。

The efficacy and selectivity to rice of eight herbicides ,including penoxsulam · cyhalofop-butyl 60 g/L OD,pe-noxsulam 2.5%OD,cyhalofop -butyl 10%EC,bispyribac -sodium 10%SC,pyribenzoxim · cyhalofop -butyl 9%ME, pyribenzoxim 5%EC,flucetosulfuron 10%WG,and metamifop 10%EC,was assessed in a field experiment .The best her-bicides in terms of both efficacy over a wide spectrum of weeds and crop selectivity were penoxsulam · cyhalofop-butyl, pyribenzoxim· cyhalofop-butyl,penoxsulam,and bispyribac-sodium.Thus these herbicides can be chosen as main her-bicides to control weeds in direct -seeded rice fields .Metamifop and cyhalofop -butyl only provided good control of grassy weeds in direct -seeding rice fields .Pyribenzoxim and flucetosulfuron effectively controlled broad -leaved weeds and sedges but their effect on grassy weeds was limited .Therefore penoxsulam· cyhalofop-butyl,pyribenzoxim· cyhalo-fop-butyl,penoxsulam,and bispyribac-sodium are promising herbicides for direct -seeded rice production in China .
