(4) The results of these experiments indicate that a number of seed-borne 

 fungous diseases, such as wheatscab (Gibberella saubinetii and Fusarium 

 spp.), primary infections only, and spotblotch of barley (Helmintho- 

 sporium sativum), are practically eliminated by the dry-heat treatment 

 as used. Other diseases like netblotch {H. teres), stripe disease (H. gra- 

 mineum) of barley, and Helminthosporium blotch of oats {H. avenaer 

 sativae), as well as loose smut of barley and smuts of oats, are markedly 

 reduced by the dry-heat treatment without materially injuring the ger- 

 mination of the seed.
