How to Manage Pests
UC Pest Management Guidelines
Some species of bacteria or other microorganisms either cause or are associated with a copious white frothy material that exudes from the axil of leaf petioles and the main stem and may drip 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.
The cause of this malady is unknown and currently there are no management recommendations regarding it. The problem has been observed on the primary bell-shaped variety "Black Bell" as well as on other varieties. Removing the infected plants may help reduce the spread.
