Biochemical Characteristics of Black Gram, Vigna mungo Infected with Root-Knot Nematode, Meloidogyne incognita Treated with Leaf Extract of Magilam, Mimusops elengi

The research has been carried out to evaluate the effect of leaf extract of Mimusopselengi on the biochemical constituents such as carbohydrate, peroxidase and chlorophyll content of the black gram, Vignamungo infected with different inoculum levels (5, 10, 15, 20 and 25 egg masses) of root-knot nematode, Meloidogyneincognita after 65 days of treatment. From this study, the carbohydrate and chlorophyll content were found to be decreased with increasing inoculum levels of egg masses and increased with increasing concentrations (5, 10, 15, 20 and 25 ppm) of leaf extract except peroxidase activity.
