Objective
Ergot is a fungal disease of the inflorescence of cereals and grasses caused especially by Claviceps purpurea. A diseased plant develops a dark sclerotium or ergot body in place of a healthy kernel; the body contains a range of toxic alkaloids that contaminate the grain. This method is applicable to wheat and rye. The Official U.S. Standards for Grain define ergoty wheat and rye as grains that contain, respectively, more than 0.05% and 0.30% ergot.
