PORT ST. LUCIE - Citrus canker is spreading into Florida grapefruit country with discoveries of the disease in an Indian River County grove and a St. Lucie County subdivision.
State agriculture officials on Friday said citrus canker was found for the first time in Indian River County, with 45 infected trees in Cobb Grove. Seven more infected trees were found in St. Lucie County. Canker in St. Lucie was first found Wednesday on a "sentinel" tree, one of 150,000 citrus trees checked regularly by U.S. Department of Agriculture staffers.
