Didymella bryoniae, also known by the synonym Mycosphaerella melonis, is an ascomycete fungal plant pathogen that causes gummy stem blight in the Cucurbitaceae family, including cantaloupe, cucumber, muskmelon and watermelon. Its asexual stage is called Phoma cucurbitacearum, and when the pathogen infects the fruit of cucurbits rather than the stem the resulting disease is called black rot.

Didymella bryoniae, also known by the synonym Mycosphaerella melonis, is an ascomycete fungal plant pathogen that causes gummy stem blight in the Cucurbitaceae family, including cantaloupe, cucumber, muskmelon and watermelon.
Article text
Regular benzimidazole fungicide applications can control this pathogen, but certain D. bryoniae isolates have been found to be resistant to benzimidazole fungicides in greenhouse settings and in the field.
Article text, control method
Currently cultural practices and fungicides work well in greenhouses and in the field only if D. bryoniae is diagnosed in the early stages of disease development.
