aThe biocontrol efficacy was calculated using the following formula: biocontrol efficacy (%) = (the disease index of water control − the index of treatment)/the disease index of water control × 100%. The disease indices were investigated 10 days after the inoculation of Blumeria graminis f. sp. tritici.
bHBI: hours before inoculation.
The treatment did not have biocontrol effects.
