Early Blight

Alternaria solani

early blightearly blight

Leaf symptoms of early blight are large irregular patches of black, necrotic tissue surrounded by larger yellow areas. The leaf spots have a characteristic concentric banding appearance (oyster-shell or bull’s eye).

Minimize wetting of the leaves by using drip or furrow irrigation. Infection occurs rapidly during periods of warm, wet weather. Fungicide sprays control the disease effectively.
