Objective  The aim of this study is to evaluate the efficacy of the strain  Paenibacillus polymyxa  HX-140, isolated from the rhizosphere soil of rape, to control Fusarium wilt of cucumber seedlings caused by  Fusarium oxysporum  f. sp.  cucumerinum .    Results  Strain HX-140 was able to produce protease, cellulase, β-1,3-glucanase and antifungal volatile organic compounds. An in vitro dual culture test showed that strain HX-140 exhibited broad spectrum antifungal activity against soil-borne plant pathogenic fungi. Strain HX-140 also reduced the infection of Fusarium wilt of cucumber seedlings by 55.6% in a greenhouse pot experiment. A field plot experiment confirmed the biocontrol effects and further revealed that antifungal activity was positively correlated with inoculum size by the root-irrigation method. Here, inoculums at 10 6  10 7  and 10 8  cfu/mL of HX-140 bacterial suspension reduced the incidence of Fusarium wilt of cucumber seedling by 19.5, 41.1, and 50.9%, respectively.    Conclusions  Taken together, our results suggest that  P. polymyxa  HX-140 has significant potential in the control of Fusarium wilt and possibly other fungal diseases of cucumber.
