Abstract
The interactions of Meloidogyne incognita, Rotylenchulus reniformis and Tylenchorhynchus brassicae on eggplant were studied in pot experiments. In single species inoculations, multiplication of each nematode declined and the proportion of males increased at higher inoculum levels. In concomitant inoculations, mutual inhibition in population increase occurred and sex-ratios were altered. Reduction in plant weight was less in concomitant inoculations, than the sum total of reductions in their single species inoculations. However, when R. reniformis and T. brassicae were together, their sex-ratios remained unchanged and multiplication of R. reniformis was not affected.
