![]() ![]() Diseased plant parts can be shredded and composted if "hot composting" techniques are used (pile temperatures should exceed 120° F throughout and piles should be turned two to three times).This may be helpful where the disease causes severe blighting each year leading to reduced yields. Apply a synthetic fungicide or an organic fungicide (fixed copper) according to label directions, early in the season, when symptoms appear to slow the spread of the disease.Remove infected leaves during the growing season and remove all infected plant parts at the end of the season. ![]() Prune off the lowest 3-4 leaf branches once plants are well established and starting to develop fruits.Keep plants well mulched to minimize soil splashing.To muddle matters further, early blight is occasionally mistaken for Septoria leaf spot because the two diseases infect tomatoes at the same time. Monitor transplants carefully for signs of this disease. What does early blight look like Early blight’s Latin name is sometimes confused with a form of tomato rot, alternaria, a different tomato problem altogether.Provide adequate spacing to increase air circulation and remove all suckers that emerge from the plant base.The disease spores are wind-blown, allowing the disease to spread through a garden or neighborhood.Įarly blight symptoms on fruit Lesions with a yellow halo on foliage A severe early blight infection Management The disease can spread during wet or dry weather but is favored by rainfall and heavy dews. Infected, dead leaves may stick to fruits. When leaves die, fruits become more vulnerable to sunscald. Use preventative treatment options, like a sulfur fungicide, before powdery mildew even forms.Early blight is typically splashed by rainfall onto lower leaves early in the season. It can also be transmitted on seeds and transplants. The fungus overwinters in soil and on plant debris. This is a very common foliar disease of tomato plants that can result in defoliation and reduced yields.The disease can also move to stems and fruits and produce dark lesions. Individual lesions enlarge and coalesce and can kill entire leaves. ![]() The lesions develop a "bulls-eye" pattern of concentric rings that can be seen with a hand lens. Micro-Sul Dusting/Wettable Sulfur may be applied with ground equipment or. A yellow halo usually surrounds the lesions. Most okra, tomatoes, peppers, eggplant, and pole beans also grow for several months in the garden, but they typically can be harvested continuously. PPE required for early entry to treated areas that is permitted under the.
