Abstract

Pear tree decline has become one of the greatest problems of the California pear industry. Symptoms of the disorder include small, sparse, light green leaves, little or no shoot growth, early cessation of fruit growth, wilting, scorching, and death of leaves. The trees may quickly collapse and die or they may linger for an indefinite period.
