Dissipation of Triazole Fungicides in Apples.

ABSTRACT: Triazole compounds are members of the demethylation inhibitor class of systemic agents used to combat the most widespread apple diseases worldwide, namely apple scab and powdery mildew. The dissipation kinetics of difenoconazole, mefentrifluconazole, myclobutanil, penconazole, tebuconazole and tetraconazole from commercial products in two apple cultivars (Rosana and Selena) were studied over four years. Pesticide residues in the apples were determined using the QuEChERS extraction procedure, followed by liquid chromatography-mass spectrometry analysis. Triazoles applied 84-100 days before harvest dissipated faster than those applied 44-55 days before harvest, with half-lives of 4.0-22.3 days and 7.1-43.9 days, respectively. Except for tebuconazole, all triazoles were found to be well below
