Flower blight—Ovulinia azaleae
Flower blight causes small round to larger spots on flowers. Flowers collapse, become soft, and cling
to leaves or stems. The fungus that causes flower blight is favored
by cool, wet weather. Spores are spread by splashing water.
Solutions
Remove and dispose of diseased blossoms. Remove debris from
the base of plants or pots in order
to reduce inoculum. Prune to improve air circulation and
remove lower branches where infections first occur. Do not
use overhead sprinklers. In rainy areas, applying a fungicide
such as triforine prior to
budbreak may help prevent this disease.
