GHS Hazard Classification

Reported hazard statements	H400, H410

Documented Uses

Herbicides (pyrimidinylsulfonylurea herbicides)
For early to mid post-emergence control of grass and some broad-leaved weeds in winter, spring and durum wheat, triticale and rye ... For use in combination with mefenpyr-diethyl.
Mesosulfuron-methyl can be made by reaction of methyl 2-sulfamoylchloride benzoate with 2-amino-4,6-dimethoxypyrimidine in the presence of a base.
Mesosulfuron-methyl belongs to the class of chemicals called sulfonyl ureas. The chemical works by inhibiting the enzyme acetolactate synthase (ALS), which leads to depletion of key amino acids that are necessary for protein synthesis and plant growth.
