Abstract
More and more markets develop around the world for South African grapes and it becomes a
challenge to store grapes for longer and reach the market with superior quality. The most
destructive decay fungus, Botrytis cinerea can cause huge economic losses and successful
postharvest control in the table grape industry relies on SO2. This gas not only controls the
fungus but also causes losses due to phytotoxicity. SO2 also creates allergic reactions
amongst certain people. In modern times the focus is on food safety and governments
consequently impose certain regulations and restrictions to restrict the use of chemicals and
ensure “cleaner” produce. The objective of this study was to find a steriliser to reduce B.
cinerea inoculum on the berry surface prior to storage,to be used in conjunction with the
current method of control – the SO2 generator pad.
