Fire blight is a highly destructive disease of apple and pear that can occur in commercial orchards and residential plantings. Many landscape trees and shrubs in the rose family are also susceptible to this disease. Under favorable environmental conditions, fire blight can cause severe damage in a very short period of time.
This newly revised publication provides information on symptoms, cause, disease development, and management. Color images aid in disease diagnosis.
