Medicinal plant extracts as potent source of nematicidal activities

Abstract

Extracts of two medicinal plants, Curcuma aromatica and Swertia chirata, showed a marked nematicidal and nematode-hatching inhibitory activity against root-knot nematode, Meloidogvne incognita. The nematicidal activity differed between extracts and plants. Maximum toxic activity was recorded in the hexane extract of S. chirata while the butanol extract of C. aromatica exhibited maximum inhibition to hatching of M. incognita eggs after 120 hours exposure period at 1000-ppm concentration.
