As inoculum densities of both fungi were increased, improved host growth and suppression of root galling increased (P ⩽ 0.05) ( Table 1). However, the two highest densities (108 and 1010 spore/g soil) of both fungi showed persistent and significant (P ⩽ 0.05) effects. T. harzianum was relatively more effective in improving the host growth than T. viride ( Table 2 and Table 5
