Evaluation of nematicidal activity of the essential oil of Homalomena occulta (Lour.) Schott rhizome and its major constituents against Meloidogyne incognita (Kofoid and White) Chitwood

Xin Chao Liu, Chun Qi Bai, Qi Zhi Liu, and Zhi Long Liu

In a screening program for new agrochemicals from Chinese medicinal herbs and wild plants, essential oil of Homalomena occulta (Lour.) Schott rhizome was found to possess strong nematicidal activity against the root-knot nematodes, Meloidogyne incognita (Kofoid and White) Chitwood. The essential oil of H. occulta rhizome was extracted via hydrodistillation and investigated by gas chromatography-mass spectrometry (GC-MS). A total of 39 components of the essential oil were identified. Linalool (47.7%) was the major compound of the essential oil of H. occulta followed by 4-terpineol (16.5%) and α-terpineol (11.2%) and 87.3% of the total components were monoterpenoids. The essential oil possessed strong nematicidal activity against M. incognita with a LC50 value of 156.43 µg/ml. α-Terpineol and 4-terpineol exhibited toxicity against M. incognita with LC50 values of 103.41 µg/ml and 115.17 µg/ml, respectively while linalool had a LC50 value of 180.36 µg/ml.
