| Abstract/Contents: | "Nearly all of the bentgrass seed grown in the United States is produced in Oregon. However, little is known about the occurrence of weed seed or pathogen propagule contaminants in bentgrass seed lots. This study was conducted to assess the diversity and frequency of occurrence of weed seeds, ergot (Claviceps purpurea), and seed galls (Anguina agrostis) in colonial (Agrostis capillaris L.) and creeping [Agrostis stolonifera L. var. palustris (Huds.) Farw.] bentgrass certified seed lot samples submitted to the Oregon State University Seed Laboratory during 1986-1995 and 2002-2010 for purity analysis. For colonial bentgrass, 115 different weed seed contaminants were detected, with 79 identified to species, 35 to genus, and 1 to family. For creeping bentgrass, 60 weed seed contaminants were identified to species, 29 to genus, and 3 to family. The percentage of seed lots per year with no weed contaminants ranged from 13% to 50% and 47% to 84% for colonial bentgrass and creeping bentgrass, respectively, depending on year. The number of new weed seed contaminants in colonial and creeping bentgrass increased at a rate of 2.7 and 1.9 per year, respectively. During 2002-2010, the percentage of seed lots with ergot per year was 44-77% for colonial bentgrass and 16-30% for creeping bentgrass. Seed galls were found in 2-15% of colonial bentgrass seed lots, but were not detected in creeping bentgrass. This study revealed a wide and increasing diversity of weed seed contaminants in colonial and creeping bentgrass, and provided evidence of increasing ergot severity in colonial bentgrass." |
