Abstract/Contents:"Experiments were conducted in Missouri, Kentucky and Tennessee in 1998 and 1999 to test the efficacy of triclopyr in controlling dallisgrass (Paspalum dilatatum). This research was based on 1997 observations by Bullock in Tennessee. Tests conducted in 1998 were initiated to confirm the activity and identify the best formulation and application method. Natural infestations of dallisgrass in cool season turfgrasses [turfgrasses] were sprayed using a CO2 backpack sprayer. Result from 1998 confirmed the effectiveness of triclopyr (Turflon Ester) in controlling dallisgrass with greater than 80% control 10 weeks after treatment (WAT). In 1999, application timing and tankmix partners were tested. Results in 1999 showed that repeat applications of Turflon Ester two weeks apart beginning in June after dallisgrass approached full greenup provided 100% control of dallisgrass 6 WAT. Turflon Ester at the rate of 1.0 lb. ai/A provided the most consistent control over the testing period, and sequential applications produced nearly 100% control in the first season of use. No injury was observed on tall fescue however transient injury was observed when Kentucky bluegrass was treated in the summer with high rates of triclopyr."
