Ergot can be a serious disease in Kentucky bluegrass and perennial ryegrass seed crops. Currently only two fungicide chemistries are labeled for ergot and can be applied multiple times in a season for ergot and other diseases. New fungicides would provide grass
Data collected from field trials over three years suggest Priaxor® is effective at reducing ergot control in grass seed crops; several other fungicides also have the potential to reduce ergot. A large amount of variability was observed among plots treated
Reserachers: Jeremiah Dung, Oregon State University (OSU) Our research focus is to develop a comprehensive, multi-tactic IPM program for ergot in grass seed crops that incorporates chemical controls, biological controls, host plant resistance, and disease modeling....
Ergot, caused by the fungal pathogen Claviceps purpurea, is a floral disease of grasses and a persistent problem in many Kentucky bluegrass (KBG) and perennial ryegrass (PRG) seed production systems (Alderman et al. 1996, Alderman et al. 1998)….

Ergot is a major seed replacement disease of perennial ryegrass (PRG) and Kentucky Bluegrass (KBG) grown for seed in the U.S. Pacific Northwest. The disease causes yield loss, reduced seed vigor, and difficulties during harvest, cleaning, and seed lot certification. The objectives of this research were to…
