Bare root-dip treatment in the leaf extract of medicinal plants like Cymbopogon flexuosus and Calendula officinalis at different concentrations and durations caused significant reduction in the population of Meloidogyne incognita and Rotylenchulus reniformis infecting tomato and chilli. Leaf extract of C. flexuosus caused more inhibition in root-knot index and nematode multiplication of reniform nematodes than that of C. officinalis. Disease incidence caused by both the soil nematodes was found gradually decreased with an increase in the concentration of leaf extracts and duration of dip treatments. Enhancement in yield production and reduction in multiplication of the two nematodes seems to be due to dip treatment in both the crops.
