[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。
[Objective] The purpose of this study was to determine the control effect of 50% chlorpropylate SG on non-cultivated broad-leaved weeds, the best dosage and application technology in the field. [Result] The suitable dosage of 50% chloropyrimidosinic acid SG was 90-200 g ai / hm2 and the water was 450 L / hm2. The suitable application period was 10-30 cm for broad-leaved weeds. The application method was stem and leaf Spray method, 45 d after the drug control effect of 80% to 100%, 50,90 g ai / hm2 and the control agent 200 g / L flupirizine EC 187.5 g ai / hm2 control effect. [Conclusion] 50% chloropyrimidosinic acid SG had a good control effect on non-cultivated broad-leaved weeds.
