It produces a seedling blight and root rot in addition to head blight. Scab occurs on barley in all parts of Illinois but is most severe in the northern part of the state. The amount of scab that develops in a crop is determined largely by the weather. Scab reduces yields, quality, and feeding value of grain. Scabby barley is discounted severely in the market and cannot be exported. Heavily infested grain will not be eaten by Fig. 35.—Scab on barley. T

The four heads in the center show the eflfect of scab attack. A normal head is at each end of the row. Barley that has as much as 10 per cent of the kernels scabby cannot be used profitably as a feed for hogs but it may be used for cattle, sheep, and poultry without harmful effects. In certain years, such as 1928, 1938, 1939, 1942, 1943, and 1957, scab caused considerable reduction in yield of barley in Illinois. Losses in the state have ranged from a trace to 20 per cent of potential annual yield, with an average of about 4 per cent.
