For homeowners, cultural practices that reduce humidity and leaf wetness are essential for good management: avoid overcrowding and avoid wetting the foliage. If plants are irrigated in a manner that wets the foliage, water early in the day so that the leaves dry quickly. When conditions are highly favorable for disease development, fungicides may be helpful in reducing the severity of the disease. Both organic and synthetic fungicides are registered to help manage these diseases. If fungicides are used, all label instructions should be followed very carefully. Some tomato cultivars are tolerant of early blight and are recommended in areas where this disease is common.
