Almond Leaf Scorch
The bacterial disease known as almond leaf scorch presents a potentially serious threat to California almond orchards. The disease may be spread in the orchard by sharpshooter leafhoppers or spittlebugs, which feed in the xylem where water is conducted through the tree. Within a few years, affected trees become unproductive and may die. Early identification and elimination of diseased trees may minimize the problem and effectively reduce further losses. This publication highlights disease symptoms and provides management suggestions.
