LONICERA DISEASE PROBLEMS
Many fungi cause leaf spots, but chemical control is
rarely warranted.
Leaf blight caused by Herpobasidium deformans results in
dead leaves.
Various genera of powdery mildews form white powder on the
leaves.
Bacterial crown gall causes round, warty-looking growths
on the stems near the soil line. Dig out and destroy
infected plants.
