The effects of single and sequential applications of currently available herbicides at 0.5X and lX rates on St. Augustinegrass sod production were investigated. single applications were made immediantely after the field was harvested, and remaining ribbons tilled and rolled, while sequential applications were applied approximately six months later. Sod was harvested one year after the initial application with tensile strengths and root core weight recorded. Data will be presented on the herbicide treatment rates and number of application effects on sod tensile strength and root mass.
