Summary. Fusarium disease of wheat, common in the north of England, is due mainly to F. culmorum (W. G. Sm.) Sacc. and F. avenaceum (Fries.) Sacc. occurring either separately or together. Both species cause “seedling blight,”“spring yellows,” and “foot‐rot”; the foot‐rot results in “thinning out” between earing and harvest, and in “premature ripening” or “whiteheads” with “deaf ears.” Both species cause a “blight of the ears” by casual external infection, resulting in sterility of florets, or diseased grain; F. culmorum is the more frequent cause of this phase. Barley, oats and rye show corresponding phases of the disease. The pathogens overwinter in diseased material in the granary or in the field; under storage conditions they retain vitality for considerably more than one year. The cultural and diagnostic characters of the fungi are given, and control measures are discussed. The writer is indebted to Mr F. T. Brooks for advice on the preparation of this paper.
