The nematicidal activity of Phellodendron amurense rhizome-derived materials (methanol extract) toward Meloidogyne Spp. second-stage juveniles (J2) and these effects on Cucumis sativus and Cucumis melo. Results were compared with these of fosthiazate. J2 was examined using 24-well plate tests, pot bioassays (C. sativa and C. melo) and Field trials (C. melo). In 24-well plate test with J2, methanol extract of P. amurense exhibited 98.7% and 69.8% mortality at 0.25 and 0.125 mg/ml toward J2, respectively, whereas Fosthiazate showed 100% mortality at 1 mg/ml. In pot bioassays with J2, P. amurense rhizome methanol extract gave 79.5% and 57.4% mortality at 2ℓ/m2(1,000x) and 2ℓ/m2(2,000x)/3kg soil from C. sativa and 73.7% and 53.3% mortality at 2ℓ/m2(1,000x) and 2ℓ/m2(2,000x)/3kg soil from C. melo, respectively. In Field test at C. melo in greenhouse showed 55.1% and 26.9% mortality at 2ℓ/m2(1,000x) and 2ℓ/m2(2,000x) applied soil.
P. amurense rhizome-derived materials, merit further study as potential root-knot nematode control agents because of their nematicidal activity.
