代謝経路

Limited data are available in the open literature. Information presented in this summary was abstracted from the data evaluation published by the Pesticide Safety Directorate (PSD, 1995). Fludioxonil is stable to hydrolytic and soil degradation. Oxidation and hydration of the cyano moiety was observed in and on soil surfaces and probably resulted from photolytic action to yield the corresponding amides and carboxylic acids. Extensive degradation occurred at the pyrrole ring in plants and animals, including hydroxylation and oxidation, followed by ring-opening. Modification of the benzodioxyl moiety was not observed.
