摘要
2006～2007年田间药效试验结果表明,10%咪唑乙烟酸水剂749.3～1005.8mL/hm2茎叶处理15d对大豆田杂草平均株防效可达79.8%～83.1%,30d平均鲜重防效达71.8%～75.9%,平均增产12%。加5%助剂处理15d的总株防效为75.1%,显著高于相同剂量下未加助剂的处理,平均增产10%,且均对大豆安全。
Experiments of weed control by imazethapyr 10%AS in soybean field were conducted both in 2006 and 2007. The weed control efficacy was 79.8%～83.1% （based on weed plant number） 15 days after post emergence treatment with imazethapyr 10%AS at application rate of 749.3～1005.8 mL/hm^2, and 71.8%～75.9% （based on weed plant fresh weight） 30 days after treatment, respectively. The soybean yield increased by 12%. The weed control efficacy was 75.1% （based on weed plant number） 15 days after post emergence treatment with 10% imazethapyr ＋ 5% adjuvant. It was shown that imazethapyr was safe to soybean plants.
