Photolysis and hydrolysis of the fungicide procymidone in water



Photolysis and hydrolysis of the fungicide procymidone in water



Journal of Pesticide Science 9(2): 223-228



The chemical photolysis and hydrolysis of systemic fungicide procymidone [N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarboximide] were studied in buffered distilled water, or natural river and sea water. Procymidone was degraded in water mainly by hydrolysis, especially in basic media, whereas sunlight had limited effect on the breakdown of the fungicide. Hydrolysis of procymidone proceeded predominantly through neutral (pH independent) and base-catalyzed processes below pH 5 and above pH 8, respectively, while both reactions occurred at pH 5-pH 8. Within the range of pH 6-9 normally found in natural water, the half-life of procymidone by hydrolysis ranged 0.6-68 days at 15.degree. C, 2 h-18 days at 30.degree. C, and 0.5 h-8 days at 45.degree. C. Temperature dependence for the hydrolysis rate was obtained from the Arrhenius equation. The product cleaved at the cylic imide linkage was predominant in neutral and basic water, whereas the product cleaved further at the amide linkage was predominant in acidic water.
