Interpretive Summary:

Technical Abstract: "Gray mold, caused by Botrytis cinerea, limits the duration of table grape storage. Periodic sulfur dioxide (SO2) fumigation and in-package SO2 generating pads are two common strategies that protect grapes after harvest. Our objectives were to compare the effectiveness of packaging Redglobe grapes in novel sulfur dioxide-releasing perforated plastic liners (SMARTPAC, Intellipack, Santiago, Chile) to packaging in plastic perforated liners with SO2 generating pads used commercially in California and Chile. We assessed their influence on grape quality after cold storage for 51 and 73 days. Both sulfur-dioxide releasing liners performed very well and were equal to sulfur dioxide generator sheets now in commercial use."
