What is Rimsulfuron?
The Uses of Rimsulfuron
Rimsulfuron is used as a pesticide.
Definition
ChEBI: A N-sulfonylurea that is N-carbamoyl-3-(ethylsulfonyl)pyridine-2-sulfonamide substituted by a 4,6-dimethoxypyrimidin-2-yl group at the amino nitrogen atom.
Agricultural Uses
Herbicide: For controlling broadleaf weeds. Registered for use in the U.S. and Canada. A U.S. EPA restricted Use Pesticide (RUP) for some formulations. Registered for use in some EU countries.
Trade name
ACCENT®; BASIS® (rimsulfuron+thifensulfuron methyl); DPX-E9636®; DPX 79406® (nicosulfuron+rimsulfuron); Matrix® (nicosulfuron+rimsulfuron); SHADEOUT®; STEADFAST®, (nicosulfuron+rimsulfuron); TRANXIT®
Metabolic pathway
The primary degradation pathway in most of the systems examined is the contraction or rearrangement and hydrolysis of the sulfonylurea linkage to yield two products that have N-pyridyl-N- pyrimidyl urea and N-pyridyl-N-pyrimidylamine moieties, and fragments of pyridine sulfonamide, 4,6- dimethoxy-2-pyrimidylurea, and 4,6-dimethoxy-2- amino-pyrimidine, respectively. In plants, demethylation and hydroxylation reactions follow the contraction or rearrangement to give N-3,4-dihydroxy- 5-methoxy-2-pyrimidyl-N(3-ethylsulfonyl-2- pyridyl)amine.
