Weights of potted Myrobalan plum seedlings at harvest were inversely proportional to the numbers of P. neoamblycephalus or C. xenoplax added at planting time. Growth of seedlings was limited most at the temperatures which favored multiplication of each species, 20 C for P. neoamblycephalus and 26 C for C. xenoplax. High inoculum levels of either nematode species suppressed low inoculum levels of the other. Both nematodes caused darkening of roots and reduction in feeder roots, which led to waterlogging.
