The head blight, or scab, of rye was observed in 1921 in the following states: Nev; York, Delaware, Virginia, Indiana, Illinois, V/isconsin, and Missouri. It apparently did not reduce the yield in any of them. In fact, in New York only a single scabbed head was found, and, lAhile small amounts of the disease could be found in many places in several of the other states from which reports were received, the disease did not reduce the yield to any extent. V/hile scab probably is more prevalent on rye than on any one of the other small grains except wheat, it apparently seldom does any appreciable damage unless by causing seedling blight. The head blight is seldom prevalent enough to be very destructive. Anthracnose caused by Colletotriohum cereale Manns The anthracnose of rye was reported from the following states: Mew Yqink, Delav/are, Virginia, Tennessee, South Carolina, Louisiana, Ohio, Maryland, Illinois, Wisconsin, Iowa, Minnesota, and North Dakota (Fig. 49). In most of the states the disease was not especially important. However, in some of them it did some damage locally. In Tennessee, according to Sherbakoff, Hesler, and Essary, the disease did considerable damage. In South Carolina, Ludwig states that the damage v/as serious locally, particularly in one locality in which the heads were severely injured. In Ohio, where culm infection was severe enough to cause considerable kernel shriveling, the reduction in yield is estimated at be- tween .5% and \%. In Indiana there was a great deal more of the disease than h
