Essential oil was obtained by hydrodistillation from air dried aerial part of Pimenta racemosa (Mill) J.W: Moore. The oil was analysed for its constituents by means of gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). Sesquiterpene compounds (63.1%) occurred in higher proportion. The major consttuents of the oil were germacrene D (10.6%), β-elemene (8.8%), germacrene A (7.3%), selin-11-en-4-a-ol (6.3%), δ-cadinene (5,9%), β-caryophylene (5.8%), germacrene B (5.3%) and α-copaene (5.2%). The essential oil of Pimenta racemosa applied as dust formulation, was effective as a potato tuber sprout suppressant
