A few other bacterial foliar pathogens of coriander\/cilantro have been documented in the Pacific Northwest but are less common, i.e.,&nbsp;<em>Xanthomonas campestris<\/em>&nbsp;pv.&nbsp;<em>coriandri<\/em>&nbsp;and&nbsp;<em>Xanthomonas hortorum<\/em>&nbsp;pv.&nbsp;<em>carotae<\/em>. The parsley bacterial leaf spot pathogen is&nbsp;<em>Pseudomonas syringae<\/em>&nbsp;pv.&nbsp;<em>apii<\/em>.<br><b>Host crops<\/b>: Cilantro\/coriander. Based on field research, the cilantro and parsley bacterial leaf spot problems are caused by two pathogens:&nbsp;<em>Pseudomonas syringae<\/em>&nbsp;pv.&nbsp;<em>apii<\/em>&nbsp;and&nbsp;<em>P. syringae<\/em>&nbsp;pv.&nbsp;<em>coriandricola<\/em>.&nbsp;<em>Pseudomonas syringae<\/em>&nbsp;pv.&nbsp;<em>apii<\/em>&nbsp;is also the causal agent of bacterial leaf spot diseases of celery and fennel. However, these cilantro and parsley pathogens can infect other crops in the Apiaceae, so plan crop rotation with the possibility of cross infection among cilantro, parsley, celery, and fennel.<\/p>\n\n\n<div class=\"wsu-row wsu-row--quarters\" >\r\n    \n<div class=\"wsu-column\"  style=\"\">\r\n\t\n\n<figure class=\"wp-block-image alignleft size-medium is-resized\"><a
