Cucurbit wet rot (144)
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.
