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

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…
