Pacific Pests, Pathogens and Weeds


  • Worldwide distribution. A common fungus, causing rots on fruit, flowers and leaves in bean, cucumber, papaya and tomato families. A minor disease.
  • Spores are splashed from soil onto wounds made by insects, weather events or during cultivation. Also, flowers wilt, become infected, then supply spores.
  • Spread is by spores on the wind. Worse in wet weather, high temperatures and high humidity.
  • Rots occur in cold storage without producing spores.
  • Cultural control: plant spacing important for squash and zucchini, allowing leaves to dry rapidly after rain.
  • Chemical control: none recommended.
