Effect Mimusops elengi leaf extract on Meloidogyne incognita and biochemical changes of black gram

摘要

The present study was conducted to evaluate the effect of leaf extract of Mimusops elengi on the root-knot nematode Meloidogyne incognita infecting the black gram Vigna mungo with different inoculum levels of egg-masscs (5, 10, 15, 20 and 25). Plantstreated with the leaf extract of M. elengi at different concentrations (5, 10, 15, 20 and 25 ppm). The control and experimental plants were analyzed for various biochemical constituents such as, carbohydrate, protein, amino acid, lipid, proline and phenol content after 65 days of treatment. Carbohydrate and protein were found decreased with increasing inoculum levels of egg-masses and increased with increasing concentrations of leaf extract treatment and lipid, amino acid, proline and phenol content found increased with increasing inoculum levels of egg-masses and decreased with increasing concentrations of leaf extract treatment.
