The aqueous leaf extract of Vitex negundo was found to be effective for juvenile mortality of M. incognita. Efficacy of the formulation increased with increase in concentrations as well as exposure periods. While aqueous leaf extract of Eupatorium perfoliatum @ 10% concentration and V. negundo @ 10% concentration were effective in reducing the egg hatching of M. incognita. In another experiment, Cow urine @ 10% (v/v) was found to be effective for the juvenile mortality as well as in reducing the egg hatching of M. incognita. Agniastra @ 100 ml in combination with T. viride @ 2g/1000 cm3 soil played an important role in improving the plant status of tomato like shoot length, root length, shoot weight, root weight and leaf count per plant and in reducing the nematode population both in soil and in roots, this leads in reducing the root gall formation of tomato.ennullECO-FRIENDLY MANAGEMENT OF ROOT KNOT NEMATODE, Meloidogyne incognitaThesis
