Abstract

The smut commonly infecting Johnson grass in the United States is Sphacelotheca Hold and not a physiological race of S. cruenta. Tests of the reaction of Johnson grass, selections of Sudan grass and varieties and hybrid selections of sorghum to S. Hold and S. cruenta are reported. With few exceptions the sorghum selections exhibiting susceptibility to S. Hold were of known or probable origin from feterita; the kafir sorghums, which are susceptible to all forms of both S. cruenta and S. Sorghi, appeared to be immune from S. Hold. Johnson grass showed only slight susceptibility to S. cruenta; the Sudan grass selections remained free from infection with S. Hold.
