Family Solanaceae includes a number of plants used for vegetables like potato, tomato, chilli, brinjal and pepper. Symptomatology and etiology of Alternaria diseases of five vegetable crops of this family have been described in greater detail for their diagnosis. Potato a worldwide staple vegetable crop rich in starch; tomato, the “queen of kitchens”, chilli the dual purpose crop used also as spice, rich in vitamin ‘C’ content and known for its pungency; pepper (Capsicum) utilized as a mixed vegetable and brinjal (eggplant), a fruit vegetable used extensively in southern India, were found to be parasitized by eight species of Alternaria which have some closed resemblance and diversity also in their morphology. Symptoms of disease and species of Alternaria associated with them and their morphological differentiation have been given in this review.
