【摘要】 用 2 0 %精喹·乙羧氟草醚EC在大豆 3~ 4片复叶期进行茎叶处理 ,研究其除草效果及安全性。结果表明 :该药剂对大豆田杂草防除效果理想 ,但对大豆有一定药害 ;适宜剂量对大豆有轻微药害 ,但基本不影响产量。
【Abstract】 Weed control efficacy and crop injuries were study on 20% quizalofop-P-ethyl·fluoroglycofen Ec spraying in 3~4 trifid leaf stages of soybean. The results showed that excellent weed control efficacy was attained. Light soybean injuries were observed.
