How to Manage Pests
UC Pest Management Guidelines
Water Mold (Fruit Rot)
Pathogens: Pythium ultimum and other species
(Reviewed 12/13, updated 12/13)
In this Guideline:
Water-soaked lesions develop on ripe fruit in contact with wet soil. Within several days, the entire infected fruit turns into a water bag.
Avoid late-season irrigation, especially when threat of rainfall increases. Avoid wetting the top of beds when fruit is ripening. Shorter furrow irrigation runs and higher beds may lessen risk.
