EFFICACY OF SOME PLANT EXTRACTS AGAINST ROOT-KNOT (Meloidogyne javanica) OF CHILLI (Pages : 12 - 19)
R.K. SINGHA, S.M.E. HASSAN, M.M. ISLAM, N.B. ISLAM AND S.M.M. HOSSAINThe standard (S) and half-standard (S/2) leaf extract of Bermuda grass, Water spinach, Ivy leaf morning glory, Nisinda, and Justicia were tested against root-knot of chilli caused by Meloidogyne javanica in pot experiment after 10 days of transplantation. Among the plant extracts, standard (S) extract of Bermuda grass followed by Water spinach gave superior result as it had increased shoot and root length as well as fresh weight of shoot and root respectively with the lowest galling incidence and development of adult female, J2, J3 and J4 juveniles of Meloidogyne javanica in chilli. Comparatively better effect on plant growth characters with lower galling incidence and development of the nematode was observed with standard (S) extract of Ivy leaf morning glory leaf followed by standard (S) extract of Nisinda leaf. Half-standard (S/2) extract of Bermuda grass also gave promising result on plant growth characters with lower galling incidence and development of the nematode. Comparatively lower effect of plant growth character was found with half-standard (S/2) extract of Water spinach leaf followed by half-standard (S/2) extract of Ivy leaf morning glory leaf. Half standard (S/2) extracts of Nisinda and Justicia leaf were also found effective as compared to control. Download
