Pepper anthracnose caused by Colletotrichum spp. affects ripe (mature) and unripe (immature) pepper fruit. In older lesions, black structures (acervuli) may be observed. Warm, moist weather during fruit development, poorly drained soil and plant stress caused by improper fertilization practices favor disease development.
Bacterial spot caused by Xanthomonas spp.. Initial symptoms appear on the lower surfaces of leaves as small, irregular water-soaked areas. These spots enlarge as disease progresses and become purplish gray with black centers. As the disease progresses the center of the lesions drop out forming a shot-hole appearance.
