1. The pathogen grew well on the media using glucose, sucrose, fructose, maltose, rhamnose or soluble starch as carbon sources. Galactose, xylose, mannite or sorbose was not beneficial for the growth of the pathogen, however. The media with only organic or inorganic nitrogen sources were not suitable for the pathogen growth although organic nitrogen sources were better than inorganic nitrogen sources. The pathogen could also infect Allium cepa L., A. fistulosum L. and A. odorum L. under artificial inoculation conditions.
