摘要
对15%炔草酸可湿性粉剂防治小麦田杂草进行了田间药效试验。试验结果表明,15%炔草酸可湿性粉剂200～300g/hm2茎叶处理30d对禾本科杂草的株防效可达81.2%～86.6%,45d平均鲜重防效达86.2%～90.1%,平均增产15%,且对小麦安全。
Efficacy of clodinafop-propargyl 15%WP against weeds in wheat fields were studied both in 2008 and 2009.Experimental results showed that the weed control efficacy was 81.2%～86.6%（based on weed plant number） at 30 day after post emergence treatment with clodinafop-propargyl 15%WP at application rate of 200～300 g/hm2 in 2008,and 86.2%～90.1%（based on weed plant fresh weight） at 45 day after treatment in 2009,respectively.The soybean yield increased by 15%.Clodinafop-propargyl caused no phytotxicity to wheat plants.
