| 摘 要： | 咪草因防除苜蓿田杂草，经试验咪草烟用作苜蓿播后苗前土壤处理，对苜蓿药害严重。苗后早期处理使用剂量在1500、1800、2100ml／hm^23个剂量，对苜蓿田反枝苋、稗草、马唐、马齿苋等单双子叶杂草的总防效分别为76％、81％、84％，且在规定剂量内对苜蓿安全。另外，咪草烟对苜蓿田其它主要杂草一播娘蒿也有较好的防效。

| Abstract: | Imazethapyr 5% SC controls weeds in alfalfa, but this experiment indicates that imazethapyr applied to thesoil after planting and before emergence causes significant crop injury. Early postemergence treatments at 1500, 1800,or 2100 ml/ha controlled broadleaf and grass weeds including redroot pigweed (Amaranthus retroflexus), barnyardgrass(Echinochloa crusgalli), large crabgrass (Digitaria sanguinalis), and purslane (Portulaca oleracea) from 76 to 84%.Recommended rates of imazethapyr applied postemergence did not injure alfalfa. In addition, imazethapyr providedrelatively good control of other important weeds such as Descurainia sophia. |
