A new fusarium disease of corn made its appearance in Iowa, during the season of 1914, seriously injuring the corn crop 01' the state and causing a loss estimated at more than $15,000,000. It was not confined to Iowa, for reports of a similar disease were sent to the Iowa Agricultural Experiment station by H. B. Clark of Blair, Neb., who found an abundance of it there and elsewhere in that state. One of the authors observed the fusarium that same season in western I Illinois and northern Missouri and Dr. E. C. Stakman reported that it occurred in Minnesota. In the following year, 1915, the disease was again abundant, tho not as severe as in 1914.
