Table 4.

Root endophytes identified as successful antagonists against the pathogen, H. parviporum, in the antagonism assay. These samples were identified on the basis of the significance of a t-test (p-value = 0.05) comparing the mean spherical index of their pathogen partners (n = 3 trials) with the mean spherical index of the pathogen controls (n = 12).
