Spraying Roomy Red grapes with benomyl 15 days before harvesting was effective than the control in decreasing decay percentage during 77 days cold storage(2-3°C). On the other hand, it was of meaningless effect on shattering and bleaching.

Adding sodium bisulfite at a rate of 0.25 and 0.50 gms/skgs fruits just before storage minimized decay and shattering percentage. Simultaneously, no significant influence could be detected concerning its influence on bleaching. Sodium bisulffite reduced losses in grapes, weight as well as total soluble solids and acidity than the control and benomyl treatments. The studied parameters in grapes treated with benomyl and solium bisulfite as a pre and post-harvest treatment did not differ statistically than that of those treated with sodium bisulfite alone.
