Use

Azimsulfuron (DPX‐A8947) is a new rice herbicide introduced in 1996 by DuPont for the control of broadleaf weeds (including hard‐to‐control perennials). At application rates of 820 g a.i. ha1, it provides superior weed control, including E. crus-galli, when compared with the first‐generation sulfonylurea bensulfuron at 5075 g a.i. ha1. Azimsulfuron is targeted to replace or supplement bensulfuron in some applications. In Japan, in planted rice, azimsulfuron is used as a premixture with bensulfuron (6 + 30 g a.i. ha1) to boost the activity against perennial weeds. Good control has also been reported of other members of the Echinochloa family, such as E. hispidula, E. oryzicola, and E. oryzoides. Other weeds controlled include Alisma lanceolatum, A. plantago‐aquatica, Butomus umbellatus, Cyperus difformis, Scirpus maritimus, S. mucronatus, S. supinus, Heteranthera limosa, Potamogeton nodosus, Ammannia coccinea, A. robusta, Bergia capensis, and Lindernia dubia. Azimsulfuron is sold under the trade names Gulliver and Azin.
