Studies on the bio-efficacy of Monacrosporium eudermatum against root-knot nematode, Meloidogyne incognita on brinjal

Author(s): Pintoo Kumar and Ramesh Chand
Abstract: In vivo efficacy of Monacrosporium eudermatum against root-knot nematode, Meloidogyne incognita on brinjal was studied. The observations on predacity test of M eudermatum against J2 of Meloidogyne incognita showed that J2 trapping increased with the increase of J2 population in culture and the exposure time allowed for trapping being maximum at 96 hours of exposure period. The observations on plant height and root length while studying the effect of M. eudermatum in combination with various organic manures revealed that plant height and root length increased significantly in all the treatments in comparison to the inoculated, uninoculated and treated check with minimum in inoculated check. It was observed 18.12 and 6.12 in T1, 18.00 and 5.50 in T2, 17.75 and 5.37 in T3, 17.10 and 6.12 in T4, 17.07 and 5.25 in T5 respectively in descending order. The reproduction parameters of Meloidogyne incognita on brinjal i.e. Nematode population in root and soil, eggs/ plant, total nematode population and multiplication factor significant decreased in all the treatments over the inoculated check where as significant increase was observed over the treated check. The nematode population in root and soil, egg / plant, total nematode population and nematode multiplication factor was highest (121.75, 1198.00, 8642.50, 9962.25, and 6.64) in inoculated check followed by 56.75, 226.75, 3668.00, 3951.50 and 2.63 in T5, 54.25, 207.25, 2718.75, 2980.25 and 1.99 in T3, 49.50, 219.75, 2603.25, 2872.50 and 1.91 in T1, 50.00, 218.75, 2593.25, 2862.25 and 1.91 in T4, 50.50, 224.00, 2487.50, 2762.00 and 1.84 in T2 with the minimum 26.50, 122.00, 1345.50, 1494.00 and 0.99 in treated check (T8) respectively in descending order.
