摘　　要：田间药效试验表明:75%Envoke水分散粒剂对棉田落地油菜和香附子均有较好的防效。对后茬作物安全性调查结果表明,75%Envoke水分散粒剂用药30 g/hm2对后茬小麦基本安全,药后20 d播种基本对其生长无不良影响;75%Envoke水分散粒剂对甘蓝型油菜的安全间隔期在120 d以上,对其生长发育基本无不良影响,但白菜型油菜间隔120 d仍不安全。Field experiments indicated that 75%Envoke WG had good control efficacy on Brassia campestris L. and Cyperus rotundus L. ; succeeding crop safety experiments showed that 75% Envoke WG at the dose of 30 g/hm^2 was safe to wheat and the safety interval of 75% Envoke WG to Brassica napus L. was more than four months. But 75% Envoke WG was not safe to B. campestris within four months.
