During routine tree inspections in Hillsborough County, Florida, U.S. Department of Agriculture inspectors found 2 backyard citrus trees infected with citrus canker (Xanthomonas axonopodis pv. citri). Additional surveys uncovered 29 other canker infected trees, all within one square mile of each other. This is the same area where canker was found five years ago but has not been under quarantine since 2002. Hillsborough is the eighth Florida County to report a canker outbreak since successive hurricanes hit the state during August and September of this year. Under the Citrus Canker Eradication laws all citrus trees within 1,900 feet of infected trees are required to be removed. Citrus canker is a bacterial pathogen that spreads primarily by wind-driven rain and movement of infected citrus plant material or contaminated tools.
