Abstract/Contents:"The impact of ergot on production of Kentucky bluegrass grown for seed in northeastern Oregon was determined. High levels of ergot occurred in only two of six cultivars examined. In susceptible cultivars as many as 504 sclerotinia per gram of seed were detected. This equated to 47% ergot by weight, or 25% infected seed. Ergot severity (percent sclerotinia by wieght) in Kentucky bluegrass seed in 1991 to 1994 was estimated at 0.20, 0.04, 0.07, and 1.15% respectively, based on total seed production in northeastern Oregon. Percent seed replaced by sclerotinia in 1991 to 1994 was 0.05, 0.01, 0.03, and 0.44% respectively. A significant relationship between ergot severity and yield was not detected. However, a 9% reduction in marketable seed weight occurred when seed lots contaminated with ergot were recleaned to meet purity standards."
