Annual Bluegrass Weevil (ABW) was first seen in Conneticut in 1931 and has since spread throughout the Northeast , the Mid-Atlantic region, Ontario and Ohio. While we see no outbreaks on Michigan golf courses yet, because the growing conditions are similar to the Northeast, it is certain to appear here in the future.
The damage comes from older larvae that feed on the growing point of turfgrass, the point referred to as the crown. Once the crown is destroyed, the plant has no chance at recovery and dies. ABW particularly likes close cut annual bluegrass, like putting greens. The damage is severe and the critters are difficult to control as some insecticide resistance has been reported.
ABW is not yet a problem for us at OHCC, but we continue to monitor for its' eventual arrival.
