Nematicidal activity of aliphatic compounds was tested against pien wood nematode, Bursaphelenchus xylophilus. There was a significant difference in nematicidal activity among function groups. In a test with alkanols and 2-alkenols, compounds with C8-C11 chain length showed 100% nematicidal activity at 0.5 mg/mL concentration. C6-C10 2-alkenals exhibited >95% nematicidal activity, but the other compounds with C11-C14 chain length showed weak activity. Nematicidal activity of alkanoic acids with C7-C11 chain length was strong. Whole compounds belonging to hydrocarbons, alkanals and alkanoic acetate showed weak nematicidal activity at 0.5 mg/mL concentration. Nematicidal activity of compounds which showed strong nematicidal activity at 0.5 mg/mL concentration was tested at a lower concentration. At 0.25 mg/mL concentration, whole compounds except C8 alkanol, C8 2-alkenol and C7 alkanoic acid showed >80% nematicidal activity. C9-C11 alkanols, C10-C11 2-alkenols, C8-C9 2-alkenals and C9-C10 alkanoic acids showed >80% nematicidal activity at 0.125 mg/mL concentration. Only C11 alkanol exhibited strong nematicidal activity at 0.0625 mg/mL concentration
