There are several varieties of tomato blight, many of which are readily distinguishable from each other as well as conditions caused by water or nutrient deficiencies. "THE blight," however, usually refers to late season blight, aka potato blight. It is the primary killer of autumn and winter tomato crops, made even more hazardous by the fact that, as its more colloquial name implies, it can also infect and spread among several other edible plants, most infamously potato crops (having caused the Irish Potato Famine). Distinguishing between late season blight and a less threatening disease that causes similar symptoms in tomato plants, Septoria Leaf Spot, is critical to determining whether diseased tomatoes should be sprayed in an effort to control the disease, or destroyed quickly before an entire community's winter food supply is wiped out. Symptoms of late season blight are the initial appearance of moist brown spots on leaves and fruits. As these spots grow, they become thin brown rings surrounding an irregularly shaped greasy gray area. Eventually the gray areas on the leaves turn dry and papery, though they do not usually fall out as with other types of blight. Black spots may appear on stems as the blight spreads, and in especially damp areas a white fungus may develop on the brown ring surrounding the gray matter. Eventually the leaves turn yellow and die, while the fruits fall from the plant early and become breeding grounds for even more blight. Septoria leaf spot is nearly identical in appearance to late season blight, differing only slightly in pattern of attack (spreading to older leaves and stems earlier than blight). The one distinct difference is the fact that the gray areas on the fruit and leaves develop tiny raised brown pimple-like growths, which are essentially a fruiting body for the leaf spot fungus that late season blight lacks.
