Novel Endophyte Varities: What's The Difference?, S. Ray Smith, Timothy D. Phillips
Forage Symposium at the Kentucky Cattlemen’s Convention
Over the past few decades forage producers have seen several major changes in varieties of tall fescue. From the days of Kentucky 31 being the predominant variety, the first change was the development of endophyte-free tall fescue varieties. For many growers, these have been useful additions, especially when coupled with rotational grazing to reduce the risks of overgrazing, and practices that eradicate existing stands of KY-31 and preventing the reintroduction of endophyte infected KY-31. However, these endophyte-free varieties often lacked the persistence of Kentucky 31 and disappointed many early adopters. In the 30 years since the first generation of endophyte-free …

Tall fescue is a native of Europe. The exact date of its’ introduction into the United States is not known, but likely came as a contaminant in meadow fescue seed from England prior to 1880 (Figure 1). Tall Fescue was an entry in the National Herbarium Collection in 1879 and was grown in plots in Utah, Kentucky and Maryland (USDA) in 1880. In 1916, tall fescue plants were identified in Pullman, Washington with some of these plants taken to Corvallis, Oregon in 1918. Selections out of this initial planting was released in 1945 as the variety Alta.

Forage Symposium at the Kentucky Cattlemen’s Convention
Many cattle producers in Kentucky manage tall fescue as their perennial forage base. Tall fescue has served cow-calf producers well because of its productivity and persistence with minimal management. Like most things, however, “you must take some bad with the good.” The agronomic traits we like so much about tall fescue can be attributed to a fungal endophyte that infects most fescue plants. Without the endophyte, the grass is no longer productive and tolerant of environmental stresses (dry weather, low fertility, and grazing). Unfortunately, the endophyte also produces ergot alkaloids that cause a toxicosis in cattle, which costs the U.S. …
