Tall fescue toxicosis is one of the most costly disorders of livestock in the eastern U.S. It is caused by a fungal endophyte. At present, there is no cure, but proven management strategies can lessen its effect. Such strategies include replacing toxic tall fescue with cultivars that are endophyte-free or contain beneficial endophytes, interseeding other forages to dilute the toxins, rotating livestock to non-toxic pastures, and ammoniating hay. This management guide discusses the science and application of these and other management practices.
