Effectiveness of Aqueous Extract of Binahong (Anredera cordifolia (Ten.) Steenis) Leaves in Suppressing Colony Growth and Conidia Germination of Colletotrichum capsici the Causal Agents of Anthracnose Disease on ChiliAnthracnose disease caused by the fungus Colletotrichum spp. is a major disease in chili. Several studies have reported the effectiveness of some plant extracts in suppressing the growth of this pathogen and in controlling the disease. Binahong (Anredera cordifolia) plant has been widely studied and used in traditional medicine in the field of human health as well as antimicrobial on plant pathogens. This study was aimed to test the effectiveness of the aqueous extract of binahong leaves to suppress the colony growth and conidia germination of the fungus C. capsici. The concentration of binahong aqueous extract tested were 6.25%, 8.84%, 12.5%, 17.7% and 25%. Results showed binahong aqueous extract at low concentration of 6.25% was able to suppress the growth of fungal mycelium of C. capsici up to 66.88% compared to the lower effectiveness of higher tested concentrations. The aqueous extract of binahong leaves at this low concentration also tended to suppress the germination of conidia of the fungus C. capsici in in higher tested concentrations.Keywords: Colletotrichum capsici, Aqueous extract, Anredera cordifoliaABSTRAKPenyakit Antraknos yang disebabkan oleh jamur Colletotrichum spp. merupakan penyakit utama pada tanaman cabai. Beberapa penelitian melaporkan keefektifan beberapa ekstrak tanaman dalam menekan pertumbuhan patogen Colletotrichum spp. dan dalam mengendalikan penyakit Antraknos ini. Tanaman binahong sudah banyak diteliti dan digunakan dalam pengobatan tradisional di bidang kesehatan manusia maupun sebagai antimikroba patogen tanaman. Penelitian menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan pengujian keefektifan ekstrak air daun binahong terhadap pertumbuhan koloni dan perkecambahan konidia jamur C. capsici. Konsentrasi ekstrak air binahong yang diuji adalah 6,25%, 8,84%, 12,5%, 17,7% dan 25%. Hasil menunjukkan ekstrak air binahong pada konsentrasi rendah 6,25% mampu menekan pertumbuhan miselium jamur C. capsici sampai 66,88% dibandingkan keefektifan yang lebih rendah pada konsentrasi yang lebih tinggi. Ekstrak air binahong pada konsentrasi rendah tersebut juga cenderung menekan perkecambahan konidia jamur C. capsici.Kata Kunci: Colletotrichum capsici, Ekstrak air, Anredera cordifolia
