Effect of some Plant Extracts on the Larval Hatching of Meloidogyne incognita ( Kofoid & White, 1919) Chitwood, 1949-III

Effect of different ccncentrations of leaf, bark and tuber extracts of some indigenous plants known to possess anthelminthic properties has been tested on the larval hatching of Metoidogyne incognita. There was gradual increase in the larval hatching with the passage of time after treatment and the dilutions of different plant extracts tested. MaXimum inhibition in the larval hatch was found in all the concentrations of latex and leaf extracts of madar followed by the tuber extract of motha and fruit extract of lasora. The maXimum larval hatch occurred after 72 hours in all the concentrations of the plant extracts tested but was much less than the distilled water.
