Management of root-knot nematode (Meloidogyne incognita) in bottle gourd using different botanicals in pots

Abstract

A pot experiment was conducted to study the efficacy of different botanicals in varying doses for management of root-knot nematode, M. incognita in bottle gourd. The results exhibited that madar (Calotropis procera) and neem (Azadirachta indica) leaves application proved to be more effective in improving plant growth characters and reducing root-knot index and final nematode population. Among the doses tested, higher dose of 1.5 % (w/w) was more effective than lower ones.
