禾草丹除草剂开发与应用技术研究
Shanghai Agricultural Science and Technology(2012)
Abstract
以水稻旱直播田和水直播田杂草为防除目标,验证了90%禾草丹EC除草剂的防除效果及应用技术,研究结果表明,90%禾草丹EC杀草谱广,对一年生稗草、千金子、陌上菜、丁香蓼、节节草等均有较好的防效。水稻旱直播播种、盖籽、上水自然落干后单用90%禾草丹EC150~200mL/667m2或混用90%禾草丹EC100mL/667m2加10%苄磺隆WP30g/667m2,水直播播种后3~4d(根下扎、芽立起)施用90%禾草丹加安全剂120~150mL/667m2或混用90%禾草丹EC100mL/667m2加10%苄磺隆WP25g/667m2,一次用药均能有效控制直播田前期杂草的危害,综合防效均达95%左右,对水稻安全,无残留无残毒,操作方便,明显优于其它各类除草剂,经济效益、生态效益、社会效益显著提高。
