Red spot, fruit blemish, and freckles appear as red discolored areas on fruit surface. These conditions affect marketability of affected fruit. Proper cultural practices and resistant varieties help minimize incidence. Remove affected fruit. Monitor for causal factors. These leaf-spotting diseases are most active in cool, wet conditions. Remove infected foliage and improve air circulation Early detection and prompt management of symptoms help limit disease spread.
Leaf spot and blotch diseases are primarily cosmetic on established plants, though repeated years of heavy infection can weaken them. Rake up and remove fallen leaves to reduce the spore load going into the next season. Avoid overhead watering that splashes spores from the ground onto lower leaves. If the problem is severe, protective fungicide sprays during spring leaf emergence can help, but sanitation does more than chemistry for most leaf spots.
