PP 0E6128

BASF - Pesticide petition to establish tolerance. Pesticide Petition (PP 0E6128) to establish a tolerance for residues of the fungicide epoxiconazole, (2RS,3SR)-3-(2-chlorophenyl)-2-(4-fluorophenyl)-2-[(1H-1,2,4-triazol-1-yl)methyl]oxirane in or on food commodity coffee bean at 0.05 ppm. Epoxiconazole residues are extracted from coffee beans with methanol-water. After filtration and precipitation of the interfering matrix components with calcium hydroxide, epoxiconazole is extracted from the aqueous mixture with hexane and chromatographed on silica gel. The samples are then analyzed by GC/ECD. Average recovery from fortified control samples is 90 ± 8% (n=22).
