Gummy stem blight is an important disease of cucurbits in many parts of Kentucky. Under conditions favorable to disease development, commercial growers and home gardeners may experience heavy losses. This disease can occur at any point in plant growth, from seedling stage to fruit in storage. Gummy stem blight is the name given to the disease when leaves and stems are infected. Muskmelon (cantaloupe), cucumber, and watermelon are most commonly affected by this phase of the disease. Black rot refers to the same disease on fruit; it is seen less often than the foliar phase.
