CAMPANULA DISEASE PROBLEMS
Crown rot kills plants when weather conditions are moist
and temperatures are above 60 degrees. Avoid infested
soil. The disease is caused by Pellicularia rolfsii and
no chemical control is available.
Leaf spot diseases may disfigure the leaves but no
chemical controls are suggested.
Rust covers the undersides of leaves with orange or
reddish brown pustules. The leaves will dry and the
plants are stunted.
Powdery mildew causes a white powdery growth on the
leaves.
Root rot causes root decay and in wet weather a cobwebby
growth develops on the lower stems. The lower leaves rot
and upper parts of the plant wilt and die. Remove
infected plants. No chemical control is listed for this
disease caused by Pellicularia filamentosa.
Verticillium wilt may also attack Campanula. No chemical
control is available.
