Abstract

The distribution of wheat scap is worldwide; in the U.S. the disease is the most prevalent in the central and eastern regions. The fungus attacks both spring and winter wheat, as well as many other Gramineous plants, including barley, oats, rice and some wild grasses. Among dicotyledon plants, the fungus causes root and crown disease of pea and carnation. With more wheat acreage each year, a build-up of the pathogen population is likely, and therefore pose a greater problem in the future. Today’s use of cultural practices that leave large amounts of surface residue in the fields may provide the inoculum for infection of wheat florets. Although wheat headblight was researched extensively prior to 1935, little work has been done since. Contemporary investigation is needed to keep abreast of new wheat varieties, fungicides, and other control measures which could be utilized by the wheat producer against scab This paper includes studies on varietal resistance, fungicidal control, and several aspects of the epidemiology pf wheat scab. The same pathogen may cause root and crown rot of several cereal grains, but I have limited my research to headblight of wheat.
