Verwenden
Post-emergence sulfonylurea herbicide
Definition
ChEBI: A N-sulfonylurea that is 2-(carbamoylsulfamoyl)-N,N-dimethylpyridine-3-carboxamide substituted by a 4,6-dimethoxypyrimidin-2-yl group at the amino nitrogen.
Landwirtschaftliche Anwendung
Herbicide: Used as a post-emergence herbicide to control a
variety of weeds on field corn and popcorn crops. Some
formulations may be U.S. EPA restricted Use Pesticides
(RUP). Approved for use in EU countries.

Stoffwechselwegen
In the four systems investigated, the primary
degradation pathway is to yield pyridine sulfonamide
and 4,6-dimethoxy-2-aminopyrimidine. The plant and its
microsomal system include the hydroxylation pathway
at the 4-position of the pyrimidine ring, resulting in
hydrolysis products by the cleavage of the sulfonylurea
linkage. In mammals, contraction or rearrangement of
the sulfonylurea linkage for nicosulfuron and N-
demethylated nicosulfuron yields two unique products
which have the N-pyridyl-N-pyrimidyl urea moiety and
result in the uracil metabolite.

Waste disposal
It is the responsibility of chemical
waste generators to determine the toxicity and physical
properties and of a discarded chemical and to properly identify
its classification and certification as a hazardous waste and to
determine the disposal method. United States Environmental
Protection Agency guidelines for the classification determination
are listed in 40 CFR Parts 261.3. Additionally, waste generators
must consult and follow all regional, national, state
and local hazardous waste laws to ensure complete and accurate
classification and disposal methods.
