New technology to reduce damage by Botrytis cinerea in the storage of table grapes.

Research into methods of preserving grapes in good condition during storage and transport are reviewed, including work in California, USA, on methods of introducing SO2into packaged grapes on pallets in cold storage and the dosimeters available on the market. Other methods reviewed for control of B. cinerea include the use of sulfur pills in unventilated containers of grapes for export, or the use of the "Fruit Doctor", introducing SO2 into the container through a tube; internal SO2 concentrations of> 0.5% suppressing mycelial growth and the spread of mould from one berry to another; the use of bags with 1.4%, as opposed to 60% perforation, which reduced the amount of mould and gave better grape flavour. Possible alternatives to SO2 have been investigated and include solutions of ammonium bicarbonate and sodium bicarbonate, each with the addition of chlorine at 200 g/ml, which gave acceptable results; controlling oxygen and CO2 levels; immersing fruit in ethanol; exposure to UV light and to ozone.
