gummy stem blight of cantaloupe

Gummy stem blight of cantaloupe-Lesions on leaves tend to appear drier than gummy stem blight lesions on watermelon leaves. Occasionally, lesions occur on fruit, in which case the disease name is black rot. Gummy stem blight has also been observed as an important disease in transplant houses. Management of gummy stem blight depends, in part, on a good knowledge of fungicide insensitivity among isolates of gummy stem blight in Indiana
