At the 1962 Southern Weed Conference, I sunnnarized results from two studies that indicated the injection of undiluted phenoxy herbicides will kill upland scrub hardwoods more effectively and economically than diluted herbicides. Substantial·savings seemed possible through the use of cheaper chemicals, wider spacing of incisions, elimination of a carrier, and reduction of time spent in filling tools. A later and more comprehensive study, reported herein, substantiates earlier findings and provides additional information to guide landowners in their hardwood control programs.
