USGA Summary Points:Adequate nitrogen fertility to sustain moderate growth of annual bluegrass throughout the growing season (0.1 lb-N 1000 ft-2 every 7 days) has been the single most effective cultural practice that can reduce anthracnose disease. Bimonthly applications of the chemical growth regulator trinexapac-ethyl (Primo) at rates ranging from 0.10 to 0.20 fl. oz. 1000 ft-2 throughout the season have reduced anthracnose severity. The growth regulators mefluidide (Embark) and ethephon (Proxy) had an inconsistent effect on anthracnose over the past four years. However, turf treated with Embark or Proxy in the spring, with subsequent Primo applications throughout the summer, generally had less anthracnose and superior turf quality. Turf managers can use daily-double cutting and/or lightweight rolling every other day to attain acceptable Stimpmeter readings without the need to lower the height of cut. A lower height of cut intensifies damage from anthracnose, while double cutting and rolling do not encourage the disease. Four new field studies were established in 2006 and will continue through 2007 to evaluate the impact of sand topdressing, irrigation, and lightweight rolling on anthracnose disease.
