Fescue Toxicity - Syndrome caused by ingestion of endophyte-infected tall fescue plants eliciting a toxic response in the animal.

Reducing fescue toxicity:

  • Grow a legume with tall fescue.
  • Feed hay other than tall fescue in winter, when cattle are grazing toxic fescue pasture.
  • Avoid heavy applications of broiler litter or nitrogen fertilizer on tall fescue when it is sole source of pasture hay.
  • Replant infected fescue pastures with stress-tolerant tall fescue with non-toxic endophytes.
  • Plant seed of the new, improved, winter-productive Triumph variety.
  • Preform an economic analysis of the productivity and longevity of endophyte-free fescue as compared with endophyte-infected pastures.
