AB Twenty grams per chest of sodium bisulfite (NaHSO3) provided in sawdust-packed grapes Botrytis decay control equal to that from 500 ppm of dibromotetrachloroethane (DBTCE) in the sawdust after 1-2 months storage at 0°C. At 20 grams, NaHSO3 caused considerable bleaching of the fruit. The fungicidal effectiveness of NaHSO3 was inversely related to the initial moisture content of the sawdust, whereas that of DBTCE was unaffected. Intervals of a week between mixing the fungicides with sawdust and application of the mixtures to the fruit made no significant difference in effectiveness. Pads impregnated with 2.5 grams of DBTCE gave effective decay control in grapes packed in 28-pound non-sawdust containers, irrespective of location in the pack, openness of the pack, or type of container. Control was particularly effective, in polyethylene lined lugs and the fresh appearance of the berries and stems was especially marked. Impregnated tissue wraps were less effective than pads after 83 days storage. DBTCE, even at 2,000 ppm in sawdust or 10 grams per 28-pound container, caused no detectable injury, odor, or flavor in the fruit.
