EFFECT OF BAU-BIOFUNGICIDE AND SOME PLANT EXTRACTS AGAINST ROOT-KNOT (Meloidogyne javanica) OF CHILLI

Abstract

Five treatments viz. BAU-Biofungicide (7richoderma spp.), Kharazora (Teinostachynum griffithii), Upotlangra (Aschyranthus aspera) and Satodron (Leucas aspera) along with a control were tested against root-knot of Chilli caused by Meloidogyne javanica. Among the treatments, BAU-Biofungicide and satodron leaf extract gave superior result as it had increased shoot and root length, fresh weight of shoot and root as well as number of fruit and fruit weight correspondingly with the lowest galling incidence in Chilli. Better effect on plant growth characters and yield with lower galling incidence and development of the nematode was observed with Kharazora and Upotlangra leaf extract compared to control. Negative correlations between gall numbers with shoot and root length, shoot and root weight as well as number of fruit and fruit weight under different treatments indicated the superior effect of the treatments as envisaged with lower galling and the suppressive activities of the nematode.
