Cordana leaf spot

Cordana musae

Yellow or pale brown oval shaped spots appear near the leaf margins of lower leaves.
As the spots develop, the central necrotic area develops concentric zonation with surrounding yellow halo.
Individual spots enlarge or several spots coalesce to form large infected areas.
When the leaf margins are infected, small concentric spots develop which is later converted into long stripes of pale brown necrotic tissues. The stripes sometimes extend upto midrib.
