Colletotrichum gloeosporioides is a fungus that causes anthracnose disease in soybeans, resulting in pod damage and reduced seed yield and quality. Chemical fungicides are commonly used to treat this disease, but it also results in the development of fungal resistance to the chemicals. Therefore, this study aims to in vitro evaluate the efficacy of 5 crude leaf extracts against C. gloeosporioides. The results showed that Calotropis gigantea leaf extracts were found to have very high antifungal activities. Crude extract of Calotropis gigantea leaves could effectively inhibit the growth of fungal mycelium (96.15%), followed by Nicotiana tabacum (90.38%) & Tinospora cordifolia (81.85%). In conclusion, crude extracts of Calotropis gigantea leaves were found to be highly effective in inhibiting both C. gloeosporioides mycelium growth and spore germination, and they have the potential as the new natural fungicides for the management of anthracnose disease.
