摘　　要：为明确浙江中山化工集团股份有限公司25 g/L五氟磺草胺可分散油悬浮剂对移栽水稻田主要杂草的防除效果及对水稻的安全性,于2017年开展了田间药效试验。结果表明:25 g/L五氟磺草胺可分散油悬浮剂对稗草、异型莎草、泽泻、陌上菜、鸭舌草等杂草防效良好,且对水稻生长安全。药后45 d,25 g/L五氟磺草胺可分散油悬浮剂对水稻移栽田杂草的总草株防效为81.9%~94.9%,鲜重防效为81.3%~95.8%。25 g/L五氟磺草胺可分散油悬浮剂田间推荐有效成分用量为15~45 g/hm^2。In order to confirm the efficacy and application technology of penoxsulam 25 g/L OD on weeds in transplanting rice field, trials were carried out in 2017. The results showed that penoxsulam 25 g/L OD could control weeds such as Echinochloa crusgalli, Lindernia procumbens effectively, and was safe to rice. At the 45th day after treatment, the efficacies by plant number were 81.9%-94.9%, the efficacies by fresh weight were 81.3%-95.8%.
