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.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Different Lolium species, common weeds in cereal fields and fruit orchards in Chile, were reported showing isolated resistance to the acetyl CoA carboxylase (ACCase), acetolactate synthase (ALS) and 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhibiting herbicides in the late 1990s. The first case

Quinate (1,3,4,5-tetrahydroxycyclohexanecarboxylate) is a compound synthesized in plants through a side-branch of the shikimate biosynthesis pathway, which is accumulated after glyphosate and acetolactate synthase inhibiting herbicides (ALS-inhibitors) and has phytotoxic potential. The objective of this study was to evaluate the
