摘　　要：快灭灵是一种新型茎叶处理除草剂，每公顷用有效成分30g喷雾，可有效防除小麦、玉米和水稻田的多种阔叶杂草，如荞麦蔓、藜、凤花菜、苘麻、狼巴草和眼子菜等，平均防效在80％以上。快灭灵对供试作物均有一定的接触性药害，典型症状为叶片上形成枯斑，但不影响作物最终产量．Carfentrazone is a new postemergence herbicide, primarily controlling broadleaf weeds.30g ai/hm2 provided 80% or better control of Polygonum convolvulus, Chenopodium album, and Rorippa palutris in wheat,Abutilon theophasti in maize, and Bidens tripartita and Potamogeton distinctus in rice. Carfentrazone caused a small amount of foliar necrosis on the three crop species, but yields were not affected.
