Endophytes help cool season turfgrasses resist extreme heat and drought. They also can help turfgrasses resist the .
• Some newer forage varieties of tall fescue and perennial ryegrass are infected with novel endophytes, which do not produce toxins that are harmful to livestock. • In the Pacific Northwest, tall fescue and perennial ryegrass pastures should be planted to endophyte-free or novel endophyte varieties. • Where toxic-endophyte forage must be File Size: 1MB. turfgrass industry.

These papers are presented primarily to facilitate the timely dissemination of original turfgrass research for use by the turfgrass industry. Special thanks are given to those who. Sampling and Testing for Endophyte Technology of Tall Fescue. Nick Hill, Dept. Crop and Soil Sciences, University of Georgia. Recent developments utilizing non-toxic isolates of Neotyphodium spp. for forage improvement has changed thinking on endophyte technology and the necessity of sampling and testing for quality control purposes. University of Auburn forage agronomist Don Ball calls novel endophyte tall fescue the “crowning achievement” in the battle to minimize livestock production losses due to the endophyte toxins in tall fescue. The first of the novel endophyte fescue varieties to be released was Pennington’s Jesup MaxQ in
Winter freeze damage, slow growth and crown rust susceptiblity limit forage production and turf growth of annual ryegrass in East Texas. The purpose of this project is to breed, develop, and release new winter hardy, high yielding forage and turf cultivars of annual ryegrass for the southern US. The purpose is to release improved cultivars of forage-type . Abstract. Historically, ergotism in animals has been defined as a disease of livestock consuming the sclerotia of Claviceps sp. infected grasses. The gangrenous form of ergot toxicity most frequently occurs when animals are exposed to Claviceps purpurea on feed grains and pasture grasses. This type of ergotism is a great risk to livestock, especially by: 6. heads of toxic endophyte tall fescue) (Barker et al., ). Novel endophyte tall fescue varieties have been available for forage growers for 15 years, since the release of ‘Jesup MaxQ’. Jesup was released in , and initially was marketed as either an endophyte-free variety, or infected with common toxic endophyte (Bouton et al., ).
