Abstract

The interaction studies with Meloidogyne incognita and Rotylenchulus reniformis has shown that the reduction in root length was more by M. incognita (57 per cent) than by R. reniformis (34 per cent). The shoot weight and root length reduction at 200 level by M. incognita alone was more than either by R. reniformis alone or the combination of both the nematodes. In general, when both the nematodes were inoculated, the interaction effect was suppressive being additive in respect of nematode population. Both were antagonistic to each other in combined inoculations, suppressing the population of the other, with increasing levels of their respective inoculum. The suppression effect by M. incognita was more on R. reniformis.
