摘 要：
[目的]通过田间药效试验明确50%氯丙嘧啶酸SG对非耕地阔叶杂草的防治效果、最佳田间使用剂量及施药技术。[结果]50%氯丙嘧啶酸SG适宜的施用剂量为90～200 g a.i./hm2,对水450 L/hm2;施药适期为阔叶杂草10～30 cm,施药方法为茎叶喷雾法,药后45 d防效为80%～100%,50、90 g a.i./hm2与对照药剂200 g/L氯氟吡氧乙酸EC 187.5 g a.i./hm2防效相当。[结论]50%氯丙嘧啶酸SG对非耕地阔叶杂草有较好的防治效果。

摘 要：
Based on the field trials,the efficacy,optimum dosage and the spray techniques of aminocyclopyrachlor 50% SG was determined for controlling broad-leaf weeds on uncultivated field.[Results] The results of controlling after 45 days showed that the control effect of aminocyclopyrachlor 50% SG reached 80-100% at 90-200 g a.i./ha using spray method when broad-leaf weeds were 10-30 cm high.There was no significant difference between aminocyclopyrachlor 50% SG at 50,90 g a.i./ha and 200 g/L fluroxypyr at 187.5 g a.i./ha.[Conclusions] Aminocyclopyrachlor 50% SG showed better control on broad-leaf weeds in uncultivated field.
