Abstract:
Experiment was conducted to evaluate the efficacy of various botanicals against Meloidogyne incognita under pot conditions. Five indigenous botanicals i.e Azadirachta indica, Ricinus communis, Eucalyptus globules and brassica sp. (cabbage and cauliflower) were evaluated against Meloidogyne incognita under screen house conditions. Soil amended with leaves of botanicals enhanced plant growth parameter of okra and reduced the nematode reproduction. Among all the treatments, A. indica significantly reduced the nematode population as compared to untreated check. Shoot length (23.14 cm), root length (12.08 cm) and shoot weight (5.81 g) were significantly increased in soil amended with chopped leaves of Ricinus communis 20 g/kg soil while minimum number of galls was recorded in treatment where leaves of A. indica 20 g/kg soil was applied. Infestation of root-knot nematode in okra was reduced in all treated pots compared to the untreated control.
