title: Dissipation patterns of the fungicide difenoconazole (25% EC) in apples grown in Kashmir, India.
abstract: Dissipation patterns were studied following two applications of difenoconazole (score 25% EC) at 300 and 600 g ai ha(-1) as single and double dose respectively on Golden Delicious and Starkrimson cultivars of apple. Samples were collected at 0, 3, 6, 9, 12 and 30 days (harvest) post treatment. Limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.004 and 0.008 μg g(-1), respectively. Half-life periods for Golden Delicious were found to be 6.09 and 6.70 days, and for Starkrimson, these values were observed to be 5.34 and 5.80 days, at single and double doses, respectively. Difenoconazole residues dissipated below its LOQ of 0.008 μg g(-1) after 30 day post treatment at a single dose in both the cultivars. Waiting periods of 13.06 and 10.72 days are suggested for Golden Delicious and Starkrimson cultivars at a recommended dose of 300 g ai ha(-1), respectively.
