Post-harvest Decay of ‘Campbell Early’ Grape

The occurrence of post-harvest diseases and their pathogens in ‘Campbell Early’ which is the most produced grape in Korea was investigated. The ‘Campbell Early’ grapes produced in 3 main grape-producing areas were stored in a cold room (0-4°C) for 2 weeks then at room temperature for 4 weeks prior to investigation. The major post-harvest diseases occurred were gray mold, blue mold, ripe rot, new decay 1, and new decay 2. Pathogens isolated from the symptoms were identified as Botrytis cinerea for gray mold, Penicillium sclerotiorum for blue mold and Collectrichum acutatum for ripe rot. Pathogens for new decay 1 and new decay 2 were not identified yet. Incidences of new decay 1 and new decay 2 were much higher than the other 3 decays in all grapes produced from 3 areas. Gray mold and blue mold occurred at much lower frequencies than these two decays, and ripe rot occurred least.
