Antifungal of Cashew (Anacardium occidentale Linn) leaves, nutshells, and peduncle bagasse ashes extracts against sooty mould fungi (Capnodium sp)

Abstract

Abstract Different concentrations of cashew (Anacardium occidentale Linn) leaves, nutshells, and peduncle bagasse ashes extract evaluated for growth inhibition of Capnodium sp and the antifungal activity. Results revealed that different concentration of cashew leaves, nutshells, and peduncle bagasse ashes extracts showed values difference of absorbance (DA) ranging from 0.00 to 0.42. All the concentrations of extracts showed significant inhibition in the spore germination of sooty mould. The highest levels caused maximum inhibition in the spore germination followed by lower concentrations of cashew nut shells, peduncle bagasse and leaf extracts respectively. Cashew nut shells extract had a high level of total polyphenolic, flavonoid content, pH and low values of titratable acidity, which could be attributed to its potent antifungal activity.
