Abstract/Contents:Presents a study "to determine the efficacy and phytotoxicity of Acclaim Extra when applied in early spring for control of Poa trivialis. In addition, two other studies were conducted to evaluate the phytotoxicity of Acclaim Extra on creeping bentgrass and perennial ryegrass." Results include "the ratings for percent cover of Poa trivialis on May 11 showed a significantly reduced cover for the highest treatment rates (13 and 20 oz/A including reapplications). However, by the June 21 rating date the Poa trivialis had recovered to the extent that it was not distinguishable from the check. Therefore, it does not appear that early spring applications of Acclaim Extra have any lasting negative impact on Poa trivialis. Phytotoxicity ratings recorded on April 13, April 20, May 11, and June 12 revealed that the applications of Acclaim Extra did not cause unacceptable phytotoxicity to any of the grasses treated. Perennial ryegrass was treated at higher rates than creeping bentgrass, but still, no phytotoxicity occurred."
