Abstract:
Effect of different soil salinity levels (ECe) of NaCl and NaHCO3 on hatching and mortality of juveniles (J2) or root-knot nematodes, Meloidogyne incognita (race 2) and M. javanica were studied in artificial treatment. A direct correlation in hatching and salinity levels were recorded. Inhibition in hatching and juvenile mortality were highest in 5.0 mmhos/cm. At all the salinity levels, per cent mortality increased with an increase in exposure period. Hatching inhibition and mortality percentage of M. javanica were slightly greater than M.
incognita (race 2). Sodium chloride showed a greater effect than NaHCO3 for both the nematodes.
