5%咪草烟在花生田的应用

Use of Imazethapyr 5% in Peanuts

5%咪草烟在40、60、80、120、160ml/667m2剂量下对单双子叶杂草防效均比较好,对马唐、稗草、狗尾草等禾本科杂草的总防效在80%～95%,对阔叶杂草的防效在85%～96%,5%咪草烟除草效果和混剂(咪草烟40+灭草敌100ml/667m2,咪草烟40+烯草酮25ml/667m2)基本一致.5%咪草烟对花生比较安全,安全剂量在80ml/667m2以下.

Imazethapyr 5% at 600, 900, 1200, 1800, and 2400 ml/ha provided relatively good control of monocot anddicot weeds. Overall control of large crabgrass, barnyardgrass, and foxtail was 80 to 95%, while control of broadleafweeds was 85 to 96%. Control with imazethapyr 5% was essentially equivalent to that provided by two prepackagedmixtures (imazethapyr + sethoxydim at 600 + 1500 ml/ha; imazethapyr + clethodim at 600 + 375 ml/ha). Imazethapyrwas relatively safe to peanuts, with good crop safety at 1200 ml/ha.
