为了明确氯氟吡啶酯及其复配剂对直播稻田杂草的防效和对水稻的安全性,于2016年以H优518为供试水稻品种开展晚稻直播田杂草防除试验。结果表明：播后13 d喷施25 g/L氯氟吡啶酯乳油30～37.5 g/hm^2能有效防除稗草、鸭舌草、陌上菜和异型莎草;喷施32.5 g/L氯氟吡啶酯·五氟磺草胺油悬浮剂48.75～58.5 g/hm^2能有效防除稗草、鸭舌草、陌上菜、异型莎草和牛毛毡;喷施120 g/L氯氟吡啶酯·氰氟草酯乳油144～216 g/hm^2能有效防除稗草、鸭舌草、陌上菜、异型莎草和千金子。常用药剂25 g/L五氟磺草胺油悬浮剂37.5 g/hm^2能有效防除稗草、鸭舌草、陌上菜、异型莎草和牛毛毡;10%噁唑酰草胺乳油与10%氰氟草...

Taking H-you 518 as the tested rice variety, field trials were conducted to evaluate the crop selectivity and weed control effect provided by florpyrauxifen-benzyl（Rinskor？ active） and its premixes in late season direct-seeded rice in 2016. The results showed that applied at 13 days after sowing, Rinskor 25 EC at 30-37.5 g/hm^2 achieved nearly perfect control on Echinochloa crus-galli, Monochoria vaginalis, Lindernia procumbens and Cyperus difformis, whereas it＇s premix with penoxsulam 32.5 OD formulation at 48.75-58.5 g/hm^2 provided effec...
