| Abstract: | Potato black scurf caused by the soil-borne pathogenic fungus Rhizoctonia solani is one of the main causes of potato continuous cropping obstacles. A biocontrol bacterium Paenibacillus polymyxa ZF129 had signi-ficant inhibitory effect on Rhizoctonia solani that the inhibition rate on mycelial growth was 55.29% and control efficacy in greenhouse was 84.76%. Meanwhile, ZF129 exhibited significant and broad inhibitory spectrum against six pathogenic bacteria and eight pathogenic fungi. |
