Pine wood nematode (PWN), Bursaphelenchus xylophilus causes devastating damage to pines worldwide. To develop new agent for controlling PWN, alkyloxyalcohols(A-H) were synthesized and nematicidal activity was tested against PWN. As a control, monochamol, which reported to have nematicidal activity was also tested. The nematicidal activity was diffferent according to carbon chain length in compounds. LC50 values of F, G and H were as same as that of monochamol. However A-E which have shorter carbon length than F-H showed weak nematicidal activity.
