Table 1 Effects of strain EGB solid culture application on the disease incidences of cucumber Fusarium wilt, and quantities of strains FOC and EGB in soil surrounding cucumber roots

Note: In greenhouse experiment, each treatment had three repeats and the data represent the means and standard deviations (mean ± SD) from three replications. In the same column, values designated with the same letters were not significantly different (p ≤ 0.05) according to Duncan’s test. NT, no FOC or strain EGB solid culture; EGB, strain EGB solid culture only; EGBFOC, both FOC and EGB solid culture; FOC, FOC only
