eyespot

A splash-borne disease of wheat and barley (Pseudocercosporella herpotrichoides = Tapesia yallundae), causing decay at the bases of growing stems, and leading to abortion of the developing ear or to stem breakage resulting in a flattened crop. The disease is carried between seasons on crop residues, so that infection is more severe when successive susceptible crops are grown on the same field. It may be controlled by fungicidal spray or by crop rotation. Some varieties show resistance. (Order: Ascomycetes.)
