Azimsulfuron

Использование

Azimsulfuron may be used as an analytical reference standard for the determination of the pesticide in:

• Paddy field water by direct injection using liquid chromatography-hybrid triple quadrupole-linear ion trap-mass spectrometry (LC-QqLIT-MS).
• Tap and leaching water samples by solid-phase extraction (SPE), followed by LC coupled to tandem mass spectrometry (LC-MS/MS).

Общее описание

Azimsulfuron is a sulfonylurea based pesticide.

Сельскохозяйственное использование

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 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.”
