• Soft, watery, colourless decay on carrot roots 
• Decayed area - covered with dull, white spores of the pathogen and a vinegar-like odour may develop
• Fungus - soil inhabitant that infects carrots through wounds
• In storage – warm temp (greater than 32°F) and improperly ventilated

Identification of pathogen:

• G. candidum - grows as a series of filamentous cells called hyphae
• Its spores, called conidia or arthrospores, are produced by fragmentation of the hyphae
• Hyphae and spores are white and appear colorless

Management:

In the field

• Good field drainage 
• Minimizing wounding of carrots

In storage

• Good sanitation (use of new or disinfected storage containers)
• Precooling and storing carrots at 32º F is essential
