Exploration and Investigation of Antifungal Activity of Plant Leaf Extracts on Growth of Scletorium rolfsii Sacc.

Abstract

Botanical fungicides are fungicides derived from plants that produce chemical compounds that potentially inhibit microbial growth. These fungicides are safe because to its not harmful to humans and the environment. In the present study, the plant materials used often compete with plant materials used for food and medicine such as galangal rhizomes and betel leaves. Therefore, it is necessary to explore materials derived from plants that have not been widely utilized. So the research was conducted to determine the effect of leaf extracts from several plants on the growth of Sclerotium rolfsii Sacc. the fungus that causes wilt disease in plants and determines the level of antifungal activity. This research was conducted using a completely randomized design (CRD). The leaf extracts used were from the plants Muntingia calabura, Terminalia cattapa, Syzygium oleina, Morinda citrifolia, Dimocarpus longan, and Artocarpus altilis with concentrations of 10%, 20%, 30%, 40%, and 0% as control. The data obtained were analyzed using variance analysis (ANOVA) with Duncan's New Multiple Range Test (DNMRT). The results showed that all treatments used could inhibit the growth of S. rolfsii Sacc because they were significantly different from the control. It was determined that antifungal activity in leaf extracts of M. calabura, T. cattapa, S. oleina, and D. longan was very strong, and also A. altilis had a strong antifungal activity, while M. citifolia had a moderate antifungal activity.
