To examine the photostability of the fungicide triadimefon [1-(4-chlorophenoxy)-3, 3-dimethyl- 1 H-(1, 2, 4-triazol-1-yl) butan-2-one] in the field, model experiments with organic solvents were performed. Photolysis in methanol, hexane, and acetone resulted in considerable formation of 1-(4-chlorophenoxy)-3, 3-dimethylbutan-2-one, 1-[(4-chlorophenoxy) methyl]-1 H-1, 2, 4-triazole, 1 H-(1, 2, 4-triazol-1-yl)-3, 3-dimethylbutan-2-one, and 1-phenoxy-3, 3- ...
