Stem dieback can be caused by fireblight, winter injury,
anthracnose (Gomerella cingulata), or adverse enviromental
conditions. If there is dieback after leaves emerge in the
spring and a definite bacterial ooze, the problem is fireblight. Other stem problems
require a sample be submitted to the North Carolina Cooperative
Extension Service for accurate diagnosis.
