Estimated percentage reduction in yield from loose smut of barley, 1^19. Stripe caused by KeIminthosporiurn firamineum Rab. 3tripe of barley was reported from a number of states in I919. In some states, particularly Iowa and Colorado, it was reported as severe. In l/isconsin the disease was much less severe than for a number of years. From Iowa, R. C. Cromwell reported finding fields with as high as 35% of plants destroyed by stripe. In Colorado, Leach reported that in "a few fields as high as 2^% of plants were completely killed". Prom Klichigan, G. K. Coons reported, "Barley stripe ; early attacK exceptionally severe". On the accompanying map are indicated the estimated percentages of re- duction in yield in states from which reports were received. It is of especial importence to note that this disease is occurring not only in the llorth on spring barley, but also in the South on winter 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 Johnson, A.
