Studies on gummy stem blight disease of cucurbits in Trinidad
Gummy stem blight disease, causal agent Didymella bryoniae (Auersw.) Rehm. (conidial state: Ascochyta melonis Potebnia) is reported on cucurbits in Trinidad. Host-range of the pathogen, as confirmed by pathogenicity test, includes watermelon (Citrullus lanatus (Thunb.) Mansf.), melon (Cucumis melo L.), pumpkin and squash (Cucurbita L.), cucumber (Cucumis sativus L.), christophine (Sechium edule (Jacq.) Swartz), bitter gourd (Momordica charantia L.), smooth loofah (Luffa cylindrica (L.) M.J. Roem.) and angled loofah (L. acutangula (L.) Roxb.). A brief description of disease symptoms is given along with loss estimates of 10-100 percent and 16-100 percent for watermelon and pumpki, respectively
