Synchytrium pogostemonis is a fungal pathogen causes budok disease of patchouli plant. A research to control the disease was conducted at Indonesian Spice and Medicinal Crops Research Institute. The research was purposed to evaluate effectiveness of mix combination and single formulas of citronella, clove, and neem essential oils against the disease. Two synthetic fungicides (benomyl and bourdeaux mixture) were also tested, as well as, water as a control treatment. One month-old patchouli plants were sprayed with single and mix combination formulas of those three essential oils (5 ml/l), benomyl (3 g/l), bourdeaux mixture (1 g/l) and water as much as (100-200 ml/plant) every two weeks for 5 times respectively. The result indicated that the mix essential oil formula of (neem+citronella) was the most effective in reducing budok disease incidence. Its effectiveness was higher (56.51%) then benomyl (47.82%) and bourdeaux mixture (52.18%). The mix formula of (citronella+neem) could be recommended for controlling budok disease of patchouli. The use of essential oil mix formulas, hopefully could control budok disease, inhibit the resistance of target pathogen, reduce phytotoxicity and concentration of the more toxic essential oil once, as well as, reduce the uses of synthetic pesticides.
