Fusarium Blight, Fusarium sp. Unusual outbreak of Fusarium trouble 
occurred during the past season (1915) in Orange, Washington, Jeffer- 
son and Green counties. The maturing heads had a dull grayish- 
brown color instead of the normal golden brown. The kernels were 
small, shrunken, and in many eases covered with mycelial growth. 
Prof. G. N. Hoffer, who co-operated in the investigation of this 
disease, found many kernels internally infected with Fusarium.
