Hydrolysis studies were conducted on aldicarb, aldicarb sulfoxide and aldicarb sulfone for 186 to 228 d. These long‐term studies show that, for a given temperature, the reaction rate constants for the three compounds are relatively constant below pH 7 and increase rapidly as the pH increases beyond 7. These rate constants generally result in shorter half‐lives (under two years in most environments) than previously assumed, and would result in aldicarb residues being less persistent in groundwater than previously expected.
