HPLC-DAD-MS/MS methods are employed here to
investigate and compare the hydrolytic and photoinduced
degradation pathways of aqueous solutions of tribenuron
methyl (methyl [2-4-methoxy-6-methyl-1,3,5-triazin-2-
yl(methyl)carbamoyl sulfamoyl]benzoate) (Scheme 1),
largely used against broad-leaved weeds in crops of
cereals and in particular of rice.
