Eco-friendly management of root-knot nematode, Meloidogyne incognita (Kofoid & White) chitwood using seed kernel extracts, cow urine and agniastra

Abstract

Two indigenous plants aqueous seed kernel extracts viz., Neem Seed Kernel (NSK) and Dharek Seed Kernel (DSK), cow urine and agniastra were evaluated for their effect on juvenile mortality and egg hatching inhibition of root-knot nematode, Meloidogyne incognita. Cow urine (93.76%) @ 10% concentration was most effective for the juvenile mortality of M. incognita followed by agniastra (91.81%) at 2% concentration. Cow urine (75.00%) was found to be most effective followed by agniastra at 2% and NSKE (66.67%) at 10% concentration for the egg hatching inhibition of M. incognita. Whereas, aqueous DSKE at 2% concentration was found least effective for juvenile mortality as well as egg hatching inhibition of M. incognita.
