The Plant Diagnostic Laboratory has been producing many golf turf samples. They’ve seen anthracnose, summer patch, slime molds, take-all, Pythium root diseases, annual bluegrass weevils, black turfgrass, ataenius, and many other signs of wear and tear.
Recently they had a sample of a mixed bent/Poa putting green turf with damage to both the annual bluegrass and the bentgass. The Poa was yellowing, but the bent was toasted too. The disease workup was negative, but the submitter also sent a container filled with annual bluegrass weevil (ABW) adults that explained the cause of the yellowing Poa. We also found chewed plants.
