Leaf gall—Exobasidium vaccinii
Leaves infected with the leaf gall fungus are partly or all thickened, distorted, and crisp. White or
pinkish spores cover the infected tissue. The fungus that causes leaf gall spreads
by air only during wet weather.
Solutions
Avoid overhead watering.
Prune only when dry. Vigorous plants can tolerate extensive
leaf galling. Handpick or prune
out galls. Rake and dispose of fallen leaves. Provide good
air circulation. If symptoms are on azalea, thin crowded
azaleas
and consider
removing
some
plants if nearby plants are closely spaced.
