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.

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.
