Verticillium Wilt is caused by a soil-borne fungus. Air-borne and mechanically-borne spores may also infect plants through open wounds. Pruners should be sanitized between cuts with a commercial sanitizer, 10% lysol disinfectant, 10% bleach, or rubbing alcohol to avoid introducing the fungus into healthy plant tissue on the infected plant and other healthy plants. Here is an excellent fact sheet on Verticillium Wilt of Woody Plants by our colleagues at the University of Kentucky http://www2.ca.uky.edu/agcollege/plantpathology/ext_files/PPFShtml/PPFS-OR-W-18.pdf
