Stem and root rot and wilt diseases of sesame incited by Macrophomina phaseolina and Fusarium oxysporum f. sp. sesami respectively were serious biotic constraints for sesame production. Investigations have been formulated on dual culture technique, cut stem inoculation experiment and soil inoculation experiment in order to assess the interaction and combined effect of Macrophomina phaseolina and Fusarium oxysporum f.sp. sesami. Macrophomina did not showed any antagonistic effect towards Fusarium and vice versa in dual culture experiment. Inoculation of healthy sesame stem with Macrophomina, Fusarium and in combination of Macrophomina +Fusarium revealed the colour of the stem changed from white to gray to black at different days of inoculations whereas the stem colour was green throughout the experimental period in control. The vascular bundle converted to dark and hollow stem in case of Macrophomina and Macrophomina + Fusarium when splitted 30 days after inoculation. Soil inoculation study revealed inoculation of Macrophomina + Fusarium recorded as low as 26.00% seed germination due to pre emergence damping off followed by in Macrophomina alone (seed germination 34%). The control pot recorded as high as 82% germination. Macrophomina is fast growing fungus as compared to fusarium, but the combination of Macrophomina and Fusarium didn’t yield any antagonistic effect and found both in assosication leading to disease severity as compared to alone.

Keywords: Combining effect, Fusarium oxysporum, Interaction, Macrophomina phaseolina, Sesame.
