Abstract

In the course of measurements of alkaloid concentrations in several thousand samples of endophyte-infected perennial ryegrass, tall fescue, and meadow fescue plants for diverse studies, we have encountered a number of samples with alkaloid concentrations which greatly exceed the highest levels reported in previous studies (e.g. Welty et al., 1994).
