The pot experiments were conducted from October 2009 to March 2010 in the Depart­ment of Plant Pathology, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh to study the effect of BAU-Biofungicide (Trichoderma spp.), Bermuda grass (Cynodon dactylon), Water spinach (Ipomoea aquatica) and Ivy leaf morninglory (Ipomoea hederacea) against root-knot of okra caused by Meloidogyne javanica using seed treatment and soil drenching methods. Among the treatments, BAU-Biofungicide and Bermuda grass leaf extract (S) gave superior result as it had increased length of shoot and root, weight of shoot and root, number of fruit and weight of fruit plant-1 correspondingly with the lowest galling incidence in okra in all methods. Better effect on plant growth characters with lower galling incidence and development of the nematode was observed with Water spinach extract (S) and Ivy leaf morninglory extract (S) compared to control. Lower effect of plant growth character was found with extract (S) of Ivy leaf morninglory followed by Water spinach leaf extract (S).
