Sicklepod (Senna obtusifolia) Management in an ALS-Modified Soybean (Glycine max)

摘要

Herbicide systems consisting of PRE, early POST, and late POST options arranged fac- torially were compared for control of sicklepod in narrow-row soybean with modified acetolactate synthase (ALS) (E. C. 4.1.3.18). Other weeds present included common cocklebur and mixed infes- tations of entireleaf, ivyleaf, pitted, and tall morningglories. PRE options were alachlor or alachlor plus metribuzin plus chlorimuron. Early POST options included chlorimuron, chlorimuron plus thi- fensulfuron, and no herbicide applied 3 wk after planting.
