Nematicidal Activities of Leaf Extract of Magilam, Mimusopselengiagainst the Egg Hatchability and Larval Mortality of Root Knot Nematode Meloidogyne incognita

The present study was undertaken to identify the new actives from plant origin for their nematicidal activities to determine the egg hatchability and larval mortality of root knot nematode Meloidogyne incognita. The leaves of Mimusopselengiwere studied for their egg hatchability and larval mortality invarious concentrations. The nematicidal activity of M.elengileaves,decrease in larval hatch as the concentration of the extracts increases andthe increase in number of juveniles hatched, as concentration decrease may be due to decrease in the concentration of the active principles. Hence, they evaluated the nematicidal potential of plant species against M. incognita. They reported a reduction in hatching and an increase in nematode mortality. The increase in exposure period also increase larvae hatch as concentrations of the treatments decreases in treatments with aqueous leaf extracts of plant species M. elengi.
