    This study has been conducted to obtain betel leaf extract that is able to control seed-borne fungal pathogens of peanuts and determine its effect on peanut seed germination. The research arranged out experimentally and used a completely randomized design (CRD), which consisted of 4 treatments and 5 replicates (without extract and some extracts of betel plant). The data obtained were statistically analyzed by analysis of variance and Duncan's New Multiple Range Test at 5% level. The results showed that the leaf extract of green betel, forest betel and the red betel could inhibit the growth of pathogenic fungi in vitro against fungi Rhizoctonia sp. Ie: 18.59%, 16.90% and 6.38% and the fungus Aspergillus sp. Ie: 32.08%, 37.53% and 33.03% comparing to no provision of betel leaf extract. Giving the leaf extract of green betel, forests betel and the red betel can also reduce the percentage of peanut seed-borne fungal infections attack by the fungus Rhizoctonia sp. Ie: 19.20%, 8.80% and 8.80% and by the fungus Aspergillus sp. Ie: 19.60%, 19.20% and 18.80% comparing to no betel leaf extract. Betel leaf extracts and without betel leaf extract resulted in a high percentage of normal seedlings (> 80%), but the red betel leaf extract gave lower seed germination than other betel leaf extract.
