In order to confirm Glomus cubense infectivity in liquid formulation exposed to different hydrostatic pressures, an experiment under controlled conditions was conducted. AMF spores were exposed to different pressures (Pressure I: 0,15, Pressure II: 0,3 and Pressure III: 0,5 MPa, respectively) for one minute before applying the inoculant into seeds of sorghum and corn. Plants grew for 30 days and fungal indicators and variables related to their growth were evaluated. The effect of different pressures didn’t affect the fungal structures morphologically. A positive response to fungal inoculation was found in sorghum and corn plants, as there were significant differences in relation to control plant. These results show that it is possible to include the liquid inoculant through fertigation systems
