Abstract
Tomato (Lycopersicon esculentumL.) is a popular, easily grown plant with highly tasty fruits, originally cultivated during pre-historic times by the Red Indian in South America; Tomato wilt is a warm weather disease caused by fungus Fusarium oxysporum f. sp. lycopersici. The first indication of disease in small plant is drooping of lower leafs with lose of green color followed by wilting & death of the plant. This study was conducted on cultural and morphological characters of tomato wilt (Fusarium oxysporum f. sp. lycopersici) which causes tomato (Lycopersicon esculentum L.). The data revealed that maximum mycelium growth was obtained in potato dextrose agar as semi-solid media. The isolates differed in their colony growth; mycelium mass, macroconidia, and microconidia produced. These variations were characters of each of the isolates with respect to cultural and morphological characters.
