Abstract: Chemical investigations on Curcuma zedoaria rhizome volatile oil, using HPLC, GC and GC-MS techniques, showed the presence of 1,8-cineole (18.5%), o- and p-cymene (18.42%) and α-phellandrene (14.93%) as major constituents followed by terpinolene (4.11% ), α-pinene (3.28%), β-turmerome (3.1% ), β-pinene (2.93% ), β-phellandrene (2.0%), etc. This oil was found to be highly insecticidal against Odontotermes obesus Rhamb. (white termite) and the minimum dose for 100% mortality was recorded as 2μL per petriplate for 24 h exposure duration. It also showed complete mycelial inhibition of Colletorichum falcatum at 4 μL per petriplate of the oil and was ineffective in controlling the mycelial growth of Aspergillus terreus, Fusarium graminearum, F. solani and Curvularia pallescens.
