Bulletin (Iowa Agricultural Experiment Station)


It is the general accepted opinion among botanists, that corn smut (Ustilago Maydis) enters the tissues of its host during the early stages of the growth of corn. These opinions are based on the careful experiments of Dr. Julius Kuehn, a German botanist.

Last spring some experiments were started on the College Farm with a view of preventing this troublesome disease. It was expected, of course, that the results at the close of the season would show a decided advantage when seed corn was treated, but to my surprise, the results were entirely negative. In the meantime a bulletin was received from Prof. Kelleman in which the results of his experiments with corn smut are given.
