Abstract:
Cucumber (Cucumis sativus L.) family Cucurbitaceae is one of the vital economical crops of Asia and Africa. Cucumber plants are affected by various diseases; among this wilt incited by Fusarium oxysporum was found to be more predominant. The wilt-infected plant initially exhibited yellowing of leaves, wilting of plants, and vascular discoloration of the stem. The present study is framed to make use of the antifungal potential of Ganoderma lucidum, Auricularia polytricha, Lentinus edodes, Schizophyllum commune, Trametes versicolor, and Auricularia auricula against Fusarium oxysporum causing wilt disease of cucumber. Results of the dual plate technique revealed that the Lentinus edodes, Schizophyllum commune, and Ganoderma lucidum showed inhibition of radial mycelial growth of F. oxysporum with (55.00%, 50.33%, and 47.78% respectively). Although the crude filtrates of mushrooms were screened at different day intervals viz., 10, 15, 20, 25, and 30 d. Among these, the crude extract at 20^th day exhibited maximum inhibition of 54.07%, 52.96%, and 47.03% of mycelial growth of F. oxysporum by L. edodes, G. lucidum, and S. commune. Hence, further study towards the identification of diverse antifungal compounds will pave for the development of bio fungicide against plant diseases.
