Leaf symptoms begin as small, pale yellow or water- soaked lesions that rapidly enlarge and turn tan to dark brown or irregular and black. As lesions merge, large areas of the leaf may appear blighted or entire leaves may die. Young cucurbit fruit may turn black, shrivel, and die if fruit pedicels are infected. Anthracnose lesions occur on both green and red pepper and tomato fruit. Lesions often have visible concentric rings that are composed of tiny fungal fruiting bodies.

Prune infected leaves off of plant and disinfect tools or gloves that have come in contact with the material to avoid spread. Crop rotation with non-host crops helps to reduce the risk of disease by reducing the amount of primary inoculum (spores) in the immediate area. If possible, plant resistant varieties and plant only certified, pathogen-free seed.
