A pot experiment under polyhouse conditions was carried out to manage the root knot nematode, Meloidogyne incognita by using different botanicals, viz., neem, aak, castor leaves and neem seed kernel powder @ 20 and 30 g/kg soil along with chemical as well as untreated checks. Soil was autoclaved and infested with root-knot nematode (1000J2/ kg soil). Chopped leaves of these phytotherapeutic substances were incorporated to the potted soil treatment wise and a waiting period of ten days was given before sowing of cucumber seeds. The results revealed that all plant growth parameters of cucumber improved while the nematode reproduction factors were suppressed significantly in case of all phytotherapeutic substances and chemical checks as compare to untreated inoculated check. However, higher dose (30 g/ kg) was significantly more effective as compared to the lower dose (20 g/ kg soil). Among phytotherapeutic substances, A. indica seed kernel powder were found to be most effective in suppressing galling (44) and final population in soil (143) followed by neem, castor and aak leaves as compare to untreated inoculated check.
