The influence of NaCl on the infectivity and reproduction of the root-knot and the reniform nematodes was studies using four concentrations (500, 1000, 2000 and 3000 ppm) of sodium chloride (NaCl) in the irrigation water of eggplant, squash and cowpea. Increasing salt concentration and consequently soil Ec resulted in significant increase in number of M. incognita galls and egg-masses/ eggplant roots as compared with the check plants (0 salt). The highest number of galls was observed at 3000 ppm NaCl. Increasing NaCl concentration in irrigation water increased females fecundity on the roots of eggplant and squash. However opposite results were observed on cowpea roots. The reniform nematode behaved differently, whereas the nematode counts increased with increasing salt concentration on cowpea and decreased on eggplant and squash. The present results indicated that higher salt concentration adversely affected the growth of treated plants and significantly increased the damage caused by nematodes. The influence of salt stress on the nematode development and reproduction depend on nematode species, salt concentration (soil EC) as well as the host plant. In general damage in plants under salt stress and infected with the reniform nematode was more pronounced than those infected with the root-knot nematode.
