Cordana leaf spot caused by the fungus Cordana musae, has been reported from a number of banana-producing areas throughout the world. Although widely distributed, it is not considered as being of much importance. Typical symptoms of this disease appear as oval, pale brown spots, and as long strips of light brown necrosed tissue sometimes extending from the leaf margins to the midrib. Large areas of the leaf may be destroyed. Diseased leaves may be quite conspicuous as the infected areas are usually surrounded by a bright yellow ororange zone.
