Burkholderia pyrrocina W1 exhibits strong inhibitory activity towards FHB caused by F. graminearum. a Burkholderia W1–W4 displayed comparable antagonistic activity towards mycelial growth of F. graminearum. b Burkholderia pyrrocina W1 (BpW1) caused swelling and abnormal hypha of F. graminearum. c BpW1 inhibited the spore germination of F. graminearum. d BpW1 displayed high activity against FHB in detached wheat head. e BpW1 was effective against FHB in field. g BpW1 inhibited DON production in the field experiments. A concentration of 2 mg/mL tebuconazole and water were used as fungicide and negative controls in Fig. 1d–f, respectively
