  • The effect of initial population densities of a Chilean population of Meloidogyne ethiopica on the growth of the grape cv Merlot was investigated in 600 cm3 clay pots. Each pot was artificially inoculated with 0, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256 or 512 eggs and second stage juveniles/cm3 soil and transplanted with one 60-day-old seedling of the grape cv. Merlot. The plants were maintained on benches with 6 replications for each initial population density in a glasshouse at 26 ± 3 °C for 45 days. Data of height and fresh top and root weight of the plants fitted to the curves of the Seinhorst model, y = m + (1 – m)zP-T. Tolerance limits (T) to the nematode for plant height, fresh top and root weight of grape were 1.3, 0.6 and 0.45 eggs and second stage juveniles/cm3 soil, respectively. The minimum relative yields (m) were 0.06, 0 and 0.2 at Pi = 64 eggs and second stage juveniles/cm3 soil for fresh top and root weight and height of grape, respectively. Maximum nematode reproduction rate was 307.2-fold at the lowest initial population density. These results provide evidence of the serious damaging effect caused by the Italian population of M. javanica to common bean. (literal)
