Variations in Infectivity Among Populations of Meloidogyne javanica on Tobacco and Pepper. R. O. Ogbuji, Crop Science Department, University of Nigeria, Nsukka, Nigeria. Plant Dis. 65:65-66. Copyright 1981 American Phytopathological Society. DOI: 10.1094/PD-65-65.

Ten populations of Meloidogyne javanica from Nigeria were tested on tobacco (NC95) and pepper (California Wonder). Except for one population that did not feed or reproduce on either crop, populations that reproduced on tobacco failed to do so on pepper and vice versa. These test plants can be used as host differentials in separating two races of M. javanica.
