摘　　要：为了探索28.6%氨氯吡·二氯吡AS在青海春油菜田防除阔叶杂草的药效及对油菜的安全性,设置28.6%氨氯吡.二氯吡AS商品量360、540、720 mL/hm2不同处理对水300 L/hm2,于油菜2～5叶期均匀喷施。结果表明,28.6%氨氯吡.二氯吡AS对春油菜田阔叶杂草有较好的防除效果,特别是对藜的鲜重防效达到71.73%以上,供试剂量范围内随着剂量的增高,其防除阔叶杂草的效果相应提高,且对油菜安全。Efficacy and security of 28.6% Picloram·Clopyralid AS against rape broad-leaved weeds were studied.28.6% Picloram·Clopyralid AS at the amount of 360,540,720 mL/hm2 in different treatments with 300 L/hm2 water were applied at the 2~5 leaf stage of rape.The results showed that 28.6% Picloram·Clopyralid AS had good control effects against the broad-leaved weeds in spring rape fields in particular;the fresh weight control effect of 28.6% Picloram·Clopyralid AS against Chenopodium album L.could be over 71.73% after applied,and the higher the dose,the higher the effect.And the agent was safety to rape.
