MORUS DISEASE PROBLEMS
Bacterial blight causes spots on the leaves and shoots.
The spots later become sunken and turn black. Infected
leaves are distorted and the shoots have black stripes.
The leaves at the twig tips wilt and die. Prune out dead
shoots in the fall.
In years favorable for leaf spots, the trees may be
defoliated. Rake up and dispose of infected leaves.
Cankers cause dieback of branches and kill trees if the
trunk is infected. Prune out infected branches and keep
the trees healthy.
Powdery mildew causes a white coating on the leaves.
