Sprinkler Rot (Phytophthora Fruit Rot)

Fruit at or near soil level rots with brown, watery decay, especially in wet conditions from overhead irrigation practices. Use drip irrigation instead of sprinklers, improve site drainage around trees, and keep fruit off wet soil.

Reduce moisture around affected tissue by improving drainage and air circulation. Remove rotted material cleanly and dispose of it away from the planting area. Avoid wounding healthy tissue during cleanup, as fresh wounds create new entry points. If the problem keeps returning, evaluate whether the site is too wet or poorly drained for the species you are growing.
