Abstract/Contents:"Triclopyr ester was evaluated for Bermudagrass (Cynodon dactylon) growth suppression where Bermudagrass is overseeded in the fall with perennial ryegrass (Lolium perenne) to maintain green color throughout the winter months. Applications of triclopyr ester were made to Bermudagrass prior to seedbed preparation and/or following the establishment of the overseeded ryegrass. Application rates of 0.06, 0.125, 0.25, and 0.5 lbs. a.e./acre were tested which are lower than those used for weed control. Evaluations indicated that triclopyr ester, applied prior to overseeding, provided bermudagrass growth suppression and enhanced the transition of the turf stand from bermudagrass to perennial ryegrass. Application of triclopyr ester at these rates did not inhibit the perennial ryegrass germination and growth, but did reduce the bermudagrass competition resulting in a greater ryegrass stand density. Some browning of the bermudagrass occurred at the higher tested rates. Hybrid varieties of bermudagrass were more susceptible to growth regulation than common bermudagrass and the effects were more pronounced. The degree of growth regulation and browning is rate-related. The length of the growth regulation effect is also rate-dependent with the higher rates providing a longer period of suppression. The overseeded ryegrass was not affected by these treatments."
