Fungicidal activity of Curcuma longa rhizome-derived materials against Botrytis cineria, Erysiphegraminis, Phytophthora infestans, Puccinia recondita, Pyricularia oryzae, and Rhizoctonia solani wastested using a whole plant method in vivo. It was compared with synthetic fungicides and fourcommercially available compounds derived from C. longa. The response varied with the tested plantpathogen. At 1000 mg/L, the hexane extract of C. longa showed fungicidal activities against E.graminis, P. infestans, and R. solani, and the ethyl acetate extract of C. longa showed fungicidalactivities against B. cineria, P. infestans, Pu. recondita, and R. solani. Curcumin was isolated fromthe ethyl acetate fraction using chromatographic techniques and showed fungicidal activities againstP. infestans, Pu. recondita, and R. solani with 100, 100, and 63% control values at 500 mg/L and 85,76, and 45% control values at 250 mg/L, respectively. In the test with components derived from C.longa, turmerone exhibited weak activity against E. graminis, but no activity was observed fromtreatments with borneol, 1,8-cineole, sabinene, and turmerone. In comparison, potent fungicidal activitywith chlorothalonil against P. infestans at 50 mg/L and dichlofluanid against B. cinerea at 50 mg/Lwas exhibited. These results may be an indication of at least one of the fungicidal actions of curcuminderived from C. longa.Keywords: Curcuma longa; curcumin; fungicidal activity; phytopathogenic fungi
