Abstract/Contents: | "Annual bluegrass (Poa annua L.), roughstalk bluegrass (Poa trivialis L.), and dollar spot (Sclerotinia homoeocarpa F.T. Bennett) control with bispyribac-sodium was evaluated in three separate trials. Studies were conducted at multiple locations in Virginia. Bispyribac injured creeping bentgrass (Agrostis stolonifera L.) for extended periods when applied sequentially at 74 g ai/ha. Creeping bentgrass injury was characterized as chlorotic foliage and increased with increasing bispyribac rate. Roughstalk bluegrass control required multiple bispyribac treatments and was best initiated in spring or summer rather than fall. Annual bluegrass was not controlled with single bispyribac treatments of 148 g ai/ha. However, perennial ryegrass (Lolium perenne L.) overseeding decreased annual bluegrass populations and plant size by over 97% and bispyribac stunted annual bluegrass and improved turfgrass aesthetics in overseeded plots. Perennial ryegrass turned chlorotic soon after bispyribac treatment but fully recovered within two weeks. Dollar spot control increased from 12 to 69% as bispyribac rate increased from 12 to 74 g ai/ha. Bispyribac at rates below 12 g ai/ha did not control dollar spot." |
