Subject: Asiatic citrus canker extends northward in Florida

The virulent Asian strain of citrus canker, Xanthomonas axonopodis pathovar citri, has been found affecting non-commercial grapefruit trees in Brevard County, FL; to date, this is the northernmost county to experience an outbreak of citrus canker in the current eradication campaign. The nearest county with an ongoing canker eradication effort is Palm Beach, which is more than 100 miles south of Brevard; in comparison, the nearest commercial citrus grove to the infected Brevard trees is about two miles. Citrus canker is spread naturally through wind and rain, and may be transported by humans on anything from truck tires to shoe soles.
