Agriculture: Tomato Pest Management Guidelines

Water Mold (Fruit Rot)

  • Pythium ultimum and other species
  • Symptoms and Signs

    Water-soaked lesions develop on ripe fruit in contact with wet soil. Within several days, the entire infected fruit turns into a water bag.

    Management

    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.
