Covered and loose srriuts of barley. (Upper figures represent covered ; lovrer figures, loo^^e smut.) consider that the loose smut of barley is of minor importance and that it is not sufficiently injurious to necessitate treatment. In a few states, however, central treating plants have been used. Giddings reports that in YJest Virginia the modified hot water treatment has been used to some extent in the -eastern part of the state, but only in small areas and under the supervision of county agents and also of some representative from the experiment station. He states that in about 50% of thje seed lots, germination was not affected while in the others the viability was somewhat reduced. In Virginia, according to Promme, the hot v/ater treatment was used on barley during the past year, and controlled almost entirely both the loose and the covered smuts. The treatment was carried out at central treating plants. The follov/ing comment by Taylor, con- cerning work conducted at the Arlington Farm, iij interesting: The fortieth-acre plats of bax-ley treated for amut by Dr. G. M. Reed show as results as last year. All varieties in tiie varie-^j-al experiments for the current year were treated by the hot v/ater method and a general examination of these plats has .shown but two smutted plants, both covered smut (U. hcrdei)â The ten plats treated v/ith formalin show occasional plants infected with covered smut. The ten untreated plats have a heavy infection of both loose and covered smuts. (Taylor, J. W. Cereal Courier I3: 70. May 10, 1^21.) Bolley suggests that the disease is at least partly amenable to the proper kind of formaldehyde treatm,ent, and says that it is much reduced on all farms on vJhich proper seed treatment is practiced Please note that the
