| Abstract/Contents: | "Field Experiments were conducted in 2000 at the Rutgers University Experimental Horticultural Farm II located in New Brunswick NJ to evaluate annual bluegrass control programs in 'Penn G-2', 'L-93', and 'Penncross' creeping bentgrass varieties established the previous fall and maintained at a fairway mowing height of 0.34 in. Annual bluegrass control programs consisted og 0.75, 0.5, or 0.38 lb a.i./A of ethofumesate applied on April 2 and May 2, or one application of 0.5 lb/A paclobutrazol applied on May 2. Ethofumesate treatments were reinitiated on September 19 with a sequential application on October 23. Paclobutrazol was also applied on October 23. An additional treatment of 1.5 lb/A of ethofumesate was applied in the fall. All ethofumesate applications were applied with 4.3 lb/A of urea using a CO2 backpack sprayer delivering 80 GPA. Annual bluegrass populations in the early spring were at an infestation level of approximately 40-45% across all three bentgrass varieties. Populations in the untreated check plots remaine stable at this level throughout the summer and into the fall. On June 22, ethofumesate applied at 0.75 lb/A reduced annual bluegrass populations by 51, 39 and 30% in 'L-93', 'Penn G-2', and 'Penncross', respectively. As the rate of ethofumesate decreased, so did the extent of annual bluegrass population reduction. This was most evident in 'Penncross'. Paclobutrazol reduced annual bluegrass populations by 30 and 27% in 'L-93' and 'Penn G-2', but only by 13% in 'Penncross'. Annual bluegrass populations increased in all treatments across each variety as the season progressed into September. Herbicide treatments had no effect on turf quality. However, the turf quality of 'Penncross' was lower compared with 'L-93' and 'Penn G-2', especially during the summer moths. This can most likely be attributed to the higher incidence of dollar spot disease in 'Penncross'. The results from the spring treatments suggest that annual bluegrass may be more readily controlled in newer creeping bentgrass varieties such as 'Penn G-2' and 'L-93' compated with 'Penncross'. However, fall treatments have not been fully evaluated." |
