Interaction of Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 Race 3 with Meloidogyne javanica (Treub, 1885) Chitwood, 1949 Race 3 in Tomato and Pepper

Abstract

More than one species of root-knot nematodes can attack field vegetables and they can interact with each other. In this study, the interaction of Meloidogyne incognita race 3 and M. javanica race 3 on susceptible host plants (Falkon and Sena) were investigated in a growth chamber under controlled conditions. Experiments were arranged as a randomized plots design with four replications. The incidence of two Meloidogyne species in tomato and pepper hosts were determined by esterase phenotypes. No interaction was observed between the species after the mixed inoculation of 1000 J2 M. incognita race 3 and 1000 J2 M. javanica race 3 on the susceptible tomato plant (P≤0.05). Among mixed inoculation of the two species in the susceptible pepper, only the incidence of M. incognita race 3 was increased, while M. javanica race 3 was not detected in host plants.
