Stem rot disease in peanut plants is one of the causes of the decline in peanut production in Indonesia. Control with vegetable pesticides is an alternative control to reduce the use of synthetic pesticides to support sustainable farming systems, preserve the environment and provide healthy food. Research aims to utilize synergistic Mansoa alliacea and Allamanda cathartica leaf extracts as alternative control of stem rot disease in peanut plants. The steps in the study include: making extracts, testing the formulation of a mixture of M. alliacea leaf extract and A. cathartica which is effective for controlling stem rot disease in peanut plants in greenhouses. The mixture formula of M. alliacea leaf extract and A. cathartica concentration of 2% (w/v) was effective in reducing the percentage of stem rot disease in peanut plants in greenhouses with productivity of pod weight higher than the control ie 1.07 tons / ha.
