【摘要】 采用田间小区试验方法进行了44%单嘧·扑灭WG防除夏谷子田杂草田间药效试验。结果表明:44%单嘧·扑灭WG在夏谷子田的用药量应为2100￣2400g/hm2,此剂量下施药后45d,药剂对杂草株数总防效为89.1%￣91.8%,对杂草的总体鲜重抑制率在85%左右。44%单嘧·扑灭WG在推荐剂量下施用对谷子安全,可以有效防除夏谷子田整个生长季中的杂草,封闭作用较好。更多还原

【Abstract】 Small plot field experiments were conducted to determine weed control efficacy of a monosulfuron plus propazine 44% water dispersible granule in millet. Results indicated that appropriate use rates of the monosulfuron plus propazine WDG were 2100 to 2400 g/ha,providing 89.1 to 91.8% reductions in weed plant numbers and about 85% inhibition of weed fresh weights across all species 45 d after application. The formulated product was safe to millet when used at the recommended rate and provided effective full season weed control in this crop.更多还原
