Different concentrations of shade-dried leaves, bark and kernels of neem were tested for their inhibitory role in egg hatching of Meloidogyne incognita. In general, with the increase in concentration and exposure period, there was reduced egg hatching. Neem kernels (S concentration) proved to be most effective which did not allow hatching even up to 11 days of exposure, and its lowest concentration (S18) allowed 69.22% hatching as against 91.66 in control. Neem bark was the least effective among the three as its S, S/4 concentrations allowed 69.8 and 88.1% eggs hatching, respectively.
