Seed 42 GOLF COURSE MANAGEMENT 05.19 2019 Oregon's Willamette Valley is the heart of cool-season grass seed production in the United States and the rest of the planet. Weather conditions in the valley affect the success of the crops and ultimately determine the price that golf courses will pay for new greens, tees, fair - ways and roughs — if seed supplies are suf - ficient to make those im- provements. Since last fall, Mother Nature has not been as cooperative as one might want, and some seeds may be in short supply. In anticipation of a shortage, prices of available perennial ryegrass seed have already risen. Perennial ryegrasses dominate this year's Seed Up - date, with eight new varieties listed. In recent years, grass breed - ers have developed improved tall fescue varieties that are denser and better tolerate shade, wear and drought. According to Leah Brilman, director of research and technical services for DLF Pickseed USA, tall fescues now look as good as Kentucky bluegrass, which is more difficult to produce and takes longer to establish. As a result, more courses from Chicago to Wisconsin are using tall fescues, where they once would have planted Kentucky bluegrass and perennial ryegrass. More tall fescue is appearing in roughs and bunker edges in the transition zone, and tall fescues are also getting high marks in the Na - tional Turfgrass Evaluation Program's (NTEP) low-maintenance trials. Three of these new tall fescue varieties are in the Seed Update. What is in the Seed Update? Each year, GCM reaches out to turfgrass seed companies across the country to learn about the new varieties that are being released or have been released since the previous year's up - date. Varieties are arranged in alpha- betical order by the English species name. Many companies provide the experimental numbers of their variet - ies so that our readers can more easily locate those varieties in the NTEP re - sults. A list of contributing companies also appears at the end of the Seed Update, as does a list of research resources that offer more detailed information about the new varieties in the update. — Teresa Carson BERMUDAGRASS Rio, Mountain View Seeds • Seed available now • Excellent turf quality • Superior cold and frost tolerance • Early spring green-up • Good wear tolerance and recovery • Top-rated establishment • 2013 NTEP (Table 41A) • 2013-2017 NTEP (JSC 2009-6-S) CREEPING BENTGRASS PC2.0, Tee-2-Green Corp. • Seed available in limited quantities • Medium green color with fine leaf texture • Dense texture with upright growth habits • Good disease resistance • Very good winter color • Great spring green-up • Ideal for overseeding and divot repair • Good heat, cold and wear tolerance • Recommended for greens, tees and fairways • 2014 NTEP – Fairway/Tee Macdonald (DLFPS-AP/3018 or AP18), DLF Pickseed USA • Seed limited now, adequate fall 2019 • Excellent turf quality • Dollar spot, anthracnose, brown patch and pink snow mold resistance • Very high density with low thatch • High Poa annua resistance • Early spring green-up • Seedling vigor, fast establishment • NTEP 2014 – Putting Greens • Rutgers Turfgrass Proceedings, (IS-AP 18)
