Description

General description

Iodosulfuron-methyl-sodium is a systemic sulfonylurea herbicide that affects the activity of acetolactate synthase (ALS) enzyme causing plant deformation, growth retardation, chlorosis and eventually death. It is absorbed by above-ground parts of weeds. This herbicide can also penetrate surface and groundwater as it has high mobility in environment.

Application

Iodosulfuron-methyl-sodium may have been used as stock reference standard in Liquid chromatography tandem-mass spectrometry (LC-MS) analysis done for the determination of sulfonylurea herbicides in tap and leaching water.
