| | Rimsulfuron Usage And Synthesis |
| Description | Rimsulfuron is an herbicide for the treatment of annual broadleaf weeds, certain grasses and perennial broadleaf weeds. It is quite effective in the treatment of glyphosate-resistant weed species such as marestail/horseweed. Its mechanism of action is through inhibiting the acetolactate synthase (ALS), which is involved in the synthesis of isoleucine, leucine and valine of plant, further blocking protein synthesis and the growth of weeds.

| | Uses | 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. |
