The rate constants for soil degradation and alkaline hydrolysis of two herbicides, metsulfuron-methyl and thifensulfuron-methyl, have been determined. in order to explain the difference in behaviour of the two compounds, the chemical and enzymatic hydrolysis of some ortho-substituted methyl benzoates and methyl 3-substituted thiophene-2-carboxylates were studied. The data are consistent with a difference in polar and steric effects of the substituents in benzene and thiophene derivatives.
