Antifungal Activity of Leaf Extracts of Polyalthia Longifolia (Sonn.) Benth. And Hook. F. Against Rhizoctonia Solani

Abstract

Phytochemicals are chemical compounds which are also called as a secondary metabolite. Different types of secondary metabolites synthesized by plants which are play important role in biotechnological application and also in antimicrobial activity. In the present study were carried out to determine in vitro the antifungal activity of alcoholic, hydroalcoholic and aqueous crude extracts of Polyalthia longifolia leaf against Rhizoctonia solani fungus. All these extracts i.e., 100% aqueous, 100% alcohol and 50% hydro alcohol used as 10mg/ml concentration with acetone solvent to control of Rhizoctonia solani. The results revealed that the extract that most effectively inhibited growth was found to be 100% alcoholic leaf extract. Finding in this study confirmed that plant extracts can be used as to develop the plant extract-based bio-formulation to control plant pathogens to reduce the dependence on the synthetic fungicides which are ecological safe and cheap.

Determination of Antifungal Activities on Some Plant Extracts on Alternaria alternata

“…In recent years, the presence of Alternaria alternata in sweet cherries has been reported in Greece (Thomidis & Tsipouridis, 2006), China (Ahmad et al, 2020;Chethana et al, 2019;Zhao & Liu, 2012), Italy (Wagas et al, 2023 and Türkiye (Şimşek et al, 2022). Many studies have emphasized the necessity for effective control of Alternaria species, which cause several diseases in many economically important cultivated plants, and various studies have been conducted on the use of environmentally friendly methods in controlling fungal diseases (Meena et al, 2020;Yadav et al, 2020).…”
