测定不同剂量的13%2甲4氯钠水剂对小麦田杂草的防除效果及安全性。试验结果表明,2甲4氯钠13%水剂6 930 g/hm2对小麦田阔叶杂草的防效显著,药后30 d的株防效和鲜重防效分别为84.8%和90.3%,且对小麦安全,可以在大田中推广应用。建议在小麦苗后4～5叶期,阔叶杂草2～4叶期进行施药。
The effect and the security of 13% MCPANa on controlling broadleaf weeds was determined in wheat field.The results showed that,the 13% MCPANa had a significantly controlling efficient on broadleaf weeds in wheat field.After treatment of 30 days,the control effects based on per wheat plant and fresh weight of the crop were 84.8% and 90.3%,respectively.It was safe to wheat and could be used widely in the field.
