摘要
通过5%咪唑乙烟酸AS与6.9%精唑禾草灵EW、15%精吡氟禾草灵EC混用,研究其在紫花苜蓿茎叶除草中的作用效果。结果表明:5%咪唑乙烟酸AS单独使用对杂草的防效优于与其它药剂混配;5%咪唑乙烟酸AS与6.9%精唑禾草灵EW或15%精吡氟禾草灵EC混配产生拮抗作用,降低防效;5%咪唑乙烟酸AS单用可使紫花苜蓿增产49.56%。
Weed control efficacy in alfalfa was investigated using a foliar treatment of an imazethapyr 5% AS plus fenoxaprop-P 6.9% EW plus fluazifop-P 15% EC mixture. Imazethapyr provided better weed control applied alone than when mixed with the other herbicides. Imazethapyr applied with either fenoxaprop-P or fluazifop-P produced antagonism and reduced control. Imazethapyr applied alone increased alfalfa yield 49.56%.
