This disease occurs under humid weather conditions. Since the disease appears early in the season, it is known as early blight. Though fruit infection is uncommon, the destruction of foliage can lead to fruit failure or make fruit prone to sunscald. Among the problems are infectious diseases of leaves, fruit and roots which reduce yield and affect fruit quality. The affected tissues are soft and water-soaked and they usually rot, leading to the collapse of the seedlings. Infected ripe tomato fruits show small, water soaked, sunken, circular spots. The plants remain pale and stunted and pod set is extremely low. In severe cases of infection, several spots coalesce to form large patches resulting in leaf blight. It is very difficult to control nematodes in an infested field since the eggs survive in the soil protected by host tissues. Occurs at the seedling stage and with older plants.
