摘  要:
采用田间小区试验方法进行了78%单嘧·扑草净WG防除麦田杂草碱茅田间药效试验。结果表明,78%单嘧·扑草净WG在麦田茎叶处理的用药量应为750~900g/hm2,在此剂量下施药后45d,药剂对碱茅株防效74.3%~74.8%,对碱茅的鲜重抑制率在80%以上。78%单嘧·扑草净WG在推荐剂量下施用对小麦安全。

摘  要:
The field experiments of 78% monosulfuron + prometryn WG in controlling wheat field weeds of Puccinellia distans (L.) were conducted. The results showed that 750 to 900 g/hm2 of 78% monosulfuron + prometryn WG had good efficacy. After 45 days of spraying, its control effect against Puccinellia distans (L.) was 74.8% to 81.9%, and its control effect of inhibiting weed fresh weight was above 80%. Wheat was safe at the recommended rate.
