N2  - Gray mold, caused by Botrytis cinerea Pers., is the most economically important postharvest disease of table grapes (Vi tis vinifera L.) (Cappellini et al., 1986). It is responsible for significant losses of table grape berries both before and after harvest, and is a major obstacle to long-distance trn.nsport and storage. Control of the disease is especially important in storage because it develops at low temperatures (-0.5°C) and spreads quickly among berries (Karabulut et al., 2004). Currently, postharvest diseases oftable grapes are controlled by postharvest application of S02, either by weekly fumigation in storage rooms or by packing grapes in polyethylene-lined boxes with S02 generator pads. These are used worldwide for the control of gray mold, caused by Botrytis cinerea, during long-term cold storage and export shipment of table grapes. Problems associated with S02 use include the following: (1) so2 residues that exceed the tolerance of 1 Omglkg of most countries, which can occur if the gas dosage is too high; (2) unsightly bleaching injuries that can occur to berries after numerous or high. dosage fumigations; (3) S(h cannot be used on organically certified grapes (Mlikota and Smilanick, 2001); and (4) because of sulfite hypersensitivity in some people, the dietary hai.ard of S(h was recognized and it was removed from the US Food and Drug Administration 'generally regarded as safe' classification in 1986 (Zahavi et al., 2000)
