Evaluation of physiological effect of fungal culture filtrate (FCF) and mycelial cell wall fraction (MCW) of Alternaria sp. on banana plant

Zalak Patel: Sardar Patel University

<div>Banana is the fifth largest agricultural commodity in the world trade. Its production has been affected by a vast array of pathogenic fungi causing high economic loss to the farmers. In spite of substantial advances in plant disease control strategies, global food supply is still threatened by a large number of pathogens and pests. In this study, the efficacy of the fungal components (FCF and MCW) prepared from <em>Alternaria</em> sp. has been used as an elicitor for induced resistance in potted and field grown banana plants against a broad spectrum of bacterial and fungal pathogens. Foliar application of elicitor was given thrice at two months of interval from the day of plantation in the field. Leaf samples were collected continuously up to seven days from the day of treatment. Elicitor treated plants showed increase in activity of defence related enzymes like phenylalanine ammonia lyase, peroxidase, polyphenol oxidase and β-1,3 glucanase as well as high content of total protein, total phenol and chlorophyll as compared to untreated plants. FCF treatment showed higher induction of defense related enzymes in treated plants than MCW treatment. Thoughtful application of the plants own defence mechanism can be useful for integrated disease management in banana.</div>
