Our study was performed to test the effects of mycorrhiza fungi and plant growth promoting
bacteria on Striga control in sorghum. AM fungi negatively impacted on Striga germination. It reduced the
number of Striga seedlings attaching and emerging, and delayed the emergence time of Striga in pot
experiment. The performance of the AMF alone or in combinations with bacterial strains was significantly
better than that of the bacteria alone in terms of reduction of Striga infestation, plant height and dry matter.
AM fungi enhanced the performance of the sorghum host, allowing it to withstand Striga damage better. The
percent reduction (82%) of Striga emergence after AM inoculation resulted in about a 28% increase in total
dry matter of sorghum over the control. The plant height and dry matter of sorghum were significantly higher
in the combinations between AM + bacteria strains. Moreover, results of this experiment suggest that
mycorrhizal management might be an important factor in an integrated management with bacteria for Striga
