Azimsulfuron Usage And Synthesis
  • UsesHerbicide.
  • Agricultural UsesAzimsulfuron (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 8–20 g a.i. ha−1, it provides superior weed control, including E. crus-galli, when compared with the first‐generation sulfonylurea bensulfuron at 50–75 g a.i. ha−1. 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. ha−1) 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.”
  • Safety ProfileVery unstable, explosivecompound. Very sensitive to heat. Samples have explodedduring analytical combustion. When heated todecomposition it emits toxic fumes of NOx. See AZIDES.
  • Safety ProfileLow toxicity by ingestion,inhalation, skin contact, and intraperitoneal routes. A mildeye irritant. When heated to decomposition it emits toxicvapors of NOx and SOx.
