摘要
对50%乙草胺微乳剂等6种除草剂品种进行防除夏玉米田杂草应用研究。结果表明:各药剂处理对一年生禾本科、阔叶杂草55d鲜重总防效均达到85%以上,其中40%异丙草·莠悬浮剂200g/667m2防效最好,为96.15%。
50% acetochlor as well as other five herbicides were tested for their effects of weed control in summer corn field. The results showed that the total control effects of herbicides for the annual gramineous weed and broadleaf weed are all above 85%. And the most effective herbicide is 40% Dual·atrazine SC(Suspension Concentrate ) 200 g/667m2 whose control effect is up to 96.15%.
