摘要
田间药效试验结果表明，硝磺·异丙·莠46%悬浮剂苗后茎叶喷雾，防除春玉米田多种1a生单、双子叶杂草效果好，杀草谱广，速效性好。药后30d，株防效均达94%以上，鲜重防效均在93%以上，用量100～300mL/667m2，且对玉米安全。综合考虑，建议该除草剂的推荐剂量为120～150mL/667m2。
The field efficiency test showed that 46% mesotrione · propisochlor · atrazine SC,by stems and leaves treatment in spring maize fields,had better weeding effect on many of annual monocotyledon and di-cotyledon weeds,broad weedicidal spectrum,and fast effectiveness. 30 days after treatment,the control effect of each plant and fresh weight were all above 93% and 94%,respectively. It was safety for corn at the dosage of 100-300mL/667m2. Taking all this into account,the recommended dose of 46% mesotrione·propi-sochlor·atrazine SC is 120-150mL/667m2.
