| Abstract/Contents: | Discusses possible chemical methods of removing perennial ryegrass from bermudagrass. States that "perennial ryegrass is commonly used in the transition zone of the United Staes for overseeding both common bermudagrass and hybrid bermudagrass sports fields." Lists potential benefits of overseeding, including "reduced winter weed invasion, increased turf uniformity, better wear tolerance, and increased aesthetics quality of the field." Explains that "perennial ryegrass varieties with improved heat, disease, and drought tolerance can persist longer into spring and cause delayed bermudagrass green-up...Persistent perennial ryegrass competes with bermudagrass much like a weed. Perennial ryegrass shades the bermudagrass canopy and competes with bermudagrass roots for water and nutrients." Suggests that "foramsulfuron (Revolver), rimsulfuron (Tranxit), trifloxysulfron (Monument), and metsulfuron (Manor) are ALS (acetolactate synthase)-inhibiting herbicides effective for the removal of perennial ryegrass." Presents a study conducted to "evaluate the selective control of overseeded perennial ryegrass in bermudagrass with foramsulfuron, trifloxysulfuron, metsulfuron, and rimsulfuron compared to diclofop-methyl and natural (non-chemical) transition." Details methods and materials used in the study, stating that "treatments included foramsulfuron at 10, 25, and 10 followed by (fb) 10 fl [fluid] oz [ounces]/A [acre], trifloxysulfuron at 0.5, 1, and 0.5 fb 0.5 oz/A, metsulfuron 0.5, 1, and 0.5 fb 0.5 oz/A, rimsulfuron at 1, 2, and 1 fb 1 oz/A, and diclofop-methyl at 43.5 and 43.5 fb 43.5 fl oz/A. All treatments were tank-mixed with a 90:10 nonionic surfactant at 0.25% v/v." Reports that "all herbicides provided > 90% ryegrass control except diclofop-methyl and foramsulfuron at 10 fl oz/A by three weeks after initial application...There was no bermudagrass injury observed except for sequential applications of rimsulfuron at 0.5 oz fb 0.5 oz 3 WAIT (weeks after initial treatment)." Concludes that "the use of chemical transition aids can increase the overall bermudagrass quality during the summer, which equals a better playing surface for the following fall when it is time to overseed with perennial ryegrass again." |
