Foamy Canker

Some species of bacteria or other microorganisms either cause or are associated with a copiouswhite frothy materialthat exudes from the axil of leaf petioles and the main stem and maydrip to the soil. A wound may or may not be obvious. This condition usually occurs during warm weather and when ample soil moisture is present. Fruit covered with the sticky exudate may be unmarketable. If severe, affected branches stop producing.
