Residues of the synthetic pyrethroid insecticide cypermethrin in fresh grapes of cv. Thomson Seedless and in raisins were studied. The commercial formulation Cymbush® 10% EC was applied according to the label onto the typical seedless variety and on a seed-producing clone. Samples were collected at time zero and at 15 or 21 days post-application. The raisins were produced either by submersion for 3 min in an aqueous solution of 3% potassium carbonate and 1% ethyl oleate, and dried for 15 days under direct sunlight or were dried without chemical processing. A gas chromatographic method was used for the analysis of residues. The residues in the grapes at the recommended preharvest interval (15 days) ranged from 0.23 to 0.41 mg kg -1 , whereas those in raisins ranged from 0.25 to 0.46 mg kg -1 . |
