Fire Blight
Apples, crabapples and pears are susceptible in spring to a bacterial disease known as fire blight (fireblight). The most noticeable symptom is the sudden death of the new leaves at the end of a branch. The dead sprouts may be scattered on the tree or may only occur on one side. If many branches on a pear tree are infected, they may all turn black, like the tree was burned, leading to the name “fire blightâ€. It is spread mainly by bees and flies that visit infected flowers when the tree is blooming and then take the disease to other parts of the tree.
