摘要: 为明确15%嗪吡嘧磺隆·五氟磺草胺可分散油悬浮剂的田间药效及安全性,采用茎叶喷雾法进行田间药效试验。结果表明,15%嗪吡嘧磺隆·五氟磺草胺可分散油悬浮剂田间拟推荐剂量为67.50~112.50 g (a.i.)/hm2。药后30 d,对杂草株防效和鲜重防效分别高达98.39%和98.83%。供试药剂在拟推荐剂量内使用可有效防除移栽水稻田杂草且对水稻安全。

Abstract: Aiming to confirm the control effects of 15% metazosulfuron·penoxsulam dispersible oil suspending agent(OD) against annual weeds and safety in transplant rice field, field pharmacodynamic experiments were carried out by the stem and leaf spray methods. The results showed that the recommended dosage of 15% metazosulfuron·penoxsulam OD in field were 67.50~112.50 g (a.i.)/hm2. At 30 day after spraying treatment, the weeds control effects on quantity and on fresh weight were 98.39% and 98.83%, respectively. Within the range of recommended dose,15% metazosulfuron·penoxsulam OD could effectively control weeds in transplant paddy field, and it was safety to rice.

Key words: metazosulfuron, penoxsulam, efficacy, safety
