To examine the photostability of the fungicide triadimefon[1-(4-chlorophenoxy)-3,3-dimethyl-1H-(1,2,4-triazol-1-yl)butan-2-one] in the field, model experimentswith organic solvents were performed.Photolysis in methanol, hexane, and acetone resulted inconsiderable formation of 1-(4-chlorophenoxy)-3,3-dimethylbutan-2-one,1-[(4-chlorophenoxy)methyl]-1H-1,2,4-triazole,1H-(1,2,4-triazol-1-yl)-3,3-dimethylbutan-2-one, and1-phenoxy-3,3-dimethyl-1H-(1,2,4-triazol-1-yl)butan-2-one.Therate of photodegradation in different solvents followed first-orderrate kinetics with a significantcorrelation coefficient.Keywords: Triadimefon; photodegradation; photoproducts; solvents; ratekinetics
