Botrytis rot in grapes during cold storage can be eliminated by a low concentration of sulphur dioxide inside the cold rooms. An automatic control system for maintaining the required concentrationhas been developed. Air is periodically drawn from the cold room and bubbled through a blue iodine-starch solution. The degree of discolouration is determined electro-optically, and used to alter the setting of a motorised valve in the sulphur dioxide supply line, if necessary. A gas concentration of between 8 and 13 ppm was maintained over a seven-day test period. This is well within the required limits.
