Biological control of sap-stain fungi in poplar wood

18 isolates of antagonistic bacteria collected from 5 plant hosts were assessed as biocontrol agents against sap-stain fungi.The results showed that M3-2,MJ-2 and M5-4 isolated from Mognolia grandiflora as well as HX1 and HX2 isolated from Photinia × fraseri were potential biocontrol agents against sap-stain fungi in poplar wood.
