Effect of Mimusops elengi leaf extract on Meloidogyne incognita and biochemical changes of black gram
C. Azhagumurugan and M.K. Rajan
ABSTRACT
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-masses (5, 10,
15, 20 and 25). Plants treated 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.
