Crown and Collar Rot

Crown and collar rot causes decay at the base of infected plants near the soil line. You notice soft, mushy tissue that may exude liquid or develop foul odor. The disease favors wet soils and poor drainage. Improve drainage, avoid wounding, and remove severely infected plants.

Water management that minimizes excessive water around the root crown is critical for management of this disease. Locate orchards on well-drained slopes if possible.
