Carrot black rot (204)
Pacific Pests, Pathogens and Weeds
Pacific Pests, Pathogens and Weeds

Summary

  • Worldwide distribution. On carrot, and other members of the carrot family (although some taxonomists dispute this, and believe the fungus only infects carrot). Importance not well documented.
  • The fungus causes: (i) damping-off; (ii) stalk infection leading to crown and root infection; (iii) black sunken storage rots.
  • Spread occurs on seed, and it is likely that spores are spread in rain splash.
  • Cultural control: healthy seed or treat with hot water (or 0.1% sodium hypochlorite) at 50°C for 30 mins.; 3-4 –year crop rotation without crops in the carrot family; collect and burn trash after harvest.
  • Chemical control: none recommended.
