Abstract
Preemergence herbicides are generally considered as a group to negatively affect hybrid bermudagrass (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy) establishment. However, little is known about the effects upon hybrid bermudagrass root growth, establishment, and sod harvestability. Several research projects were conducted at Mississippi State University to determine the effects of commonly used preemergence herbicides on hybrid bermudagrass sod production. Measured response variables included visually estimated hybrid bermudagrass cover, normalized difference vegetative index (NDVI), ratio vegetative index (RVI), relative chlorophyll concentration (CI-RE), sod tensile strength, root mass, root length, root surface area, average root diameter, and root carbohydrate concentration after application of these herbicides. While several of these preemergence herbicides initially reduced hybrid bermudagrass growth, hybrid bermudagrass was generally able to recover and outgrow the herbicidal effects by the end of the growing season.
