数据库记载的用途

Flumetsulam is a broad-spectrum, season-long herbicide used in the control of broadleaf weeds in soybeans, corn, and other major crops. Flumetsulam is applied as a soil-incorporated preplanting, preemergence, or postemergence herbicide depending on the formulation, at a maximum use rate of 80 g per hectare.
A selective inhibitor of acetolactate synthase, a key enzyme in branched chain amino acid biosynthesis.
Flumetsulam can be made by reaction of 5- methyl[1,2,4]triazolo-2-sulfonylchloride with 2,6-difluoroaniline in the presence of a base.
Preparation: W.A. Kleschick et al., European Patent Office patent 142152 (1985 to Dow). Improved process: L.H. McKendry, United States of America patent 4910306 (1990 to Dow).
Registration Notes: Outside USA: Broadstrike, Scorpion, Preside in Argentina. Broadstrike Dual Magnum and Fieldstar in Canada.
Following oral administration of (14)C-flumetsulam, approximately 50-75% of the administered radiolabel was excreted in the urine primarily as unchanged parent material, though two minor (<20% of urinary radiolabel) metabolites, believed to be conjugates of parent flumetsulam, were found in the urine of mice.
