Many substances in the tall fescue/endophyte association (Schedonorus arundinaceus/Epichloë coenophiala) have biological activity. Of these compounds only the ergot alkaloids are known to have significant mammalian toxicity and the predominant ergot alkaloids are ergovaline and ergovalinine. Because synthetically produced ergovaline is difficult to obtain, we developed a seed extraction and par...

Pollinator species such as butterflies and bees are declining globally primarily due to habitat loss. This is especially concerning within the tallgrass prairie ecoregion of North America, where the land area comprised of native vegetation has declined by an estimated 99%. Thus, tallgrass prairie restoration and management is imperative. The control of invasive plant species such as tall fescue...

Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is often managed with a cutting height ranging from 70 to 100 mm in ornamental lawns. Some autonomous mowers have been specifically designed maintain mowing the same range. Generally, operate by following random trajectories, and substantial overlapping needed obtain full coverage of working area. In case tall grass, this may cause lodgin...

Improving water conservation efforts for golf course turf is a constant industry goal. While creeping bentgrass (Agrostis stolonifera L.; CBG) the preferred fairway species throughout most of cool-humid regions, requirements alternative cool-season with better acute drought tolerance at mowing heights (e.g., <0.5 inch) are not well documented. A 2-yr field study compared two irrigation strategi...

Abstract Quercetin is a natural flavonoid with higher antioxidant capacity and anti-inflammatory. Tall fescue [Schedonorus arundinaceus (Schreb.) Dumort; E+] perennial cool-season grass for grazing livestock in North America. Fescue infected the endophyte (Neotyphodium coenophialum) produces chemicals toxic to livestock. However, impact of quercetin on alleviating toxicosis has received only li...

Environmental characteristics within a region often form site-specific agro-ecological responses to management. Using 92 fall-stockpiled tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] field trials in North Carolina and surrounding states, our objective was test the influence of two management factors (forage utilization pasture age) environmental (elevation soil textural gradients) on...

Se realizó un experimento en una cámara de germinación con el objetivo comparar la tolerancia a salinidad distintos materiales festuca alta (Schedonorus arundinaceus) libres e infectados endófito Epichloë coenophiala durante germinación. utilizó diseño bloques completos aleatorizados tres repeticiones tiempo arreglo factorial. Los factores experimentales fueron: 1) material genético alta, cuatr...

Tall fescue (Schedonorus arundinaceous (Schreb.) Dumort. nom. cons. Lolium arundinaceum Darbysh.) toxicosis results from the consumption of alkaloids released by wild-type endophytes (Epichloe coenophiala) that live in symbiosis with plant. Alkaloid causes significant production and reproductive losses which cost U.S. beef industry approximately $2 billion every year. Incorporating species cont...
