Identification of pathogen:

  • 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

In storage

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