Abstract/Contents: | "Bispyribac-sodium (hereafter referred to as bispyribac) herbicide represents on of the most significant advancements for the selective control of annual bluegrass in cool-season turfgrass. Studies conducted at Rutgers University have determined that late-spring/early summer is the timing for bispyribac application for optimum annual bluegrass control and creeping bentgrass safety. Applications in cool weather conditions provided significantly less annual bluegrass control with marginal creeping bentgrass safety. Studies have also been conducted on the response of other cool-season turfgrass species to bispyribac which demonstrated the potential to severely injure Kentucky bluegrass. Kentucky bluegrass may not adequately tolerate bispyribac at rates necessary for annual bluegrass control. Perennial ryegrass, tall fescue, and fine fescue may show initial symptoms of injury, but levels are less severe and persistent than those exhibited by Kentucky bluegrass. Bispyribac should be safe to use on perennial ryegrass, tall fescue, and fine fescue for annual bluegrass control. Additional studies have also determined that all cool-season turfgrass species, including creeping bentgrass, can be rapidly reseeded (within 10-14 days) into areas treated with bispyribac. This should allow for the potential use of bispyribac in fairway renovation to convert mixed annual bluegrass/creeping bentgrass fairways to predominately creeping bentgrass. Lastly we have been conducting studies on the long-term control of roughstalk bluegrass with bispyribac. Initial activity is high, however we have observed substantial regrowth of roughstalk bluegrass the following year. We are also currently conducting studies evaluating the influence of golf course management practices on the efficacy and safety of bispyribac as well as its potential use on bentgrass putting greens." |
