Walnut blight caused by Xanthomonas arboricola pv. juglandis (Xaj) is the most important bacterial disease in walnut production worldwide. To seek biocontrol agents against Xaj, we screened 152 endophytic bacteria isolated from 87 plants. Through dual-culture method screening, obtained four antagonistic bacteria, ATE17, BME17, CIE17, and OFE17 which were Amaranthus tricolor, Bambusa multiplex, ...
