. Diseases of wheat, oats, barley, and rye. Grain. 128 ILLINOIS NATURAL HISTORY SURVEY CIRCULAR 48 entire leaf. If a spot becomes somewhat elongated, much of the tissue above and below it loses its green color. If a spot is very broad, all of the leaf beyond the spot dies. Life History.—The scald fungus apparently overwinters on dead or living tissue of rye and wild hosts. Initial infection each year occurs from spores. On leaves infected in the fall, typical scald spots appear early the following spring. In the cool weather of spring, spores of the fungus are produced abundantly in these. Fig

Infection of leaves by the parasitic fungus responsible for this disease results in the appearance of broadly oval, bleached spots with straw-colored borders, each of which may be surrounded by a yellowish-green halo. An abundance of these spots greatly reduces the food-making capacity of afifected Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Boewe, Gideon Herman, 1895-.
