angular leaf spot of cantaloupe

Angular leaf spot-Lesions of angular leaf spot may be irregular in shape and water-soaked. Lesions may be present on the margin of the leaf, perhaps due to the presence of hydathodes which may provide a mode of entry. Chlorosis may be minor. Angular leaf spot prefers cool temperatures. This is mostly a disease of transplant facilities: I rarely observe this disease in the field. Angular leaf spot is not usually an economic problem; however, it may be confused with bacterial fruit blotch.
