<p>Anthracnose caused by <em>C. capsici </em>is the most important factor causing low yield on chili in Indonesia<em>. </em>A research was conducted to examine to examine the potential of patchouli oil in suppressing anthracnose disease development on chili. In vitro test was conducted by growing <em>C. capsici </em>on potato dextrose agar (PDA) medium that has been added with different concentration of patchouli oil, i.e. 10, 5, 2.5, 1.25 and 0.625%. Negative controls treatment (Kn) was conducted by growing <em>C. capsici </em>on PDA without patchouli oil, whereas positive controls (Kp) was conducted by growing <em>C. capsici </em>on PDA containing mancozeb fungicide. Patchouli oil -A significantly suppressed the growth of <em>C. capsici </em>compared to patchouli oil-B on 10 days after harvest, i.e. 91.15% suppression for all concentration level except for 0.625% which caused 85.92% suppression. Further examination using patchouli oil-A showed that incubation period on curative test was 8 days after inoculation (DAI) whereas on preventive and induced resistance test were 5 DAI. Disease severity at 10 DAI reached 4.8%, 23.20%, and 29.60% on curative, preventive, and induced resistance tests, respectively. Disease severity was 29.60% and 68.80% on positive control and negative control, respectively.</p>
