Inhibition effect of P. polymyxa ZYPP18 on wheat sheath blight expansion on detached leaves. (A) the disease expansion 5 d after the inoculation of R. cerealis on the detached leaves sprayed with sterile water (control) or a bacterial suspension of P. polymyxa ZYPP18 (ZYPP18); (B) the lesion length of wheat sheath blight on the detached wheat leaves. The line graph indicates the mean of the four replicates. Error bars indicate the standard deviation (SD) of the four replicates.
