Abstract
This study investigated the antifungal activities of plant extracts that inhibit Colletotrichum capsici. Four species of the Piper genus were assessed for their potential as effective natural antifungal agents against chili pathogens. Plant extracts were tested in vitro at concentrations of 5, 10, and 20 mg/mL using the poisonous food diffusion technique; they effectively inhibited mycelia growth of Colletotrichum capsici, significantly affecting fungal toxicity. The Piper betle L. crude extracts had the highest effectiveness (> 90%) against fungicides. The antifungal properties, like the Piper retrofractum Vahl., showed a significant inhibitory percentage (> 80%). Furthermore, hexane and ethyl acetate extracts of Piper nigrum L. and Piper sarmentosum Roxb. demonstrated excellent antifungal activity (> 80%). The phytochemical investigation of sample extracts revealed flavonoids, phenols, alkaloids, terpenoids, and steroids. As a result, the biological activity of plant extracts inhibited the growth of Colletotrichum capsici mycelia; they could serve as a source for the development of eco-friendly organic fungicides.
