Rye (Secale cereale L.). 



Anthracnose. Colletotrichuin cereale Manns. Tippecanoe, June, 

 1917; Monroe, Allen, July, 1917 (F. J. Pipal). Severe losses 

 were caused by this disease in several fields during the past 

 season. This disease has been reported previously on blue grass, 

 timothy and wheat.' 



Stem Smut. Urocystis occulta (Wal.) Rab. Marshall, June, 1916; 

 Tippecanoe, Putnam, June, 1917. 



Loose Smut. Ustilago sp. Tippecanoe, Putnam, June, 1917; Jasper, 

 July, 1917 (Chas. Chupp). This disease was rather rare in 

 the three fields in which it was discovered. The fungus shows 

 close resemblance to Ufitilago Tritici (Pers.) Jens., but in the 

 absence of cross inoculations it is retained as Ustilago sp. 

 Sunflower (Helianthus sp.). 



Leaf Spot. Cei'cospora Helianthi E. & E. Tippecanoe, July, 1907. 

 Turnip (Brassica Rapa L.). 



Alhiigo Candida (Pers.) Rouss. Tippecanoe, October, 1915 (G. N. 

 Hoffer). This disease has been reported previously on a num- 

 ber of other hosts.^ 

 Wheat {Triticum vulgare L.). 



Ergot, Claviceps purpurea (Fr.) Tul. Tippecanoe, Elkhart, July, 

 1917; Jasper, July, 1917 (Chas. Chupp). This disease has been 

 reported previously on rye." 



Stinking Smut, Tilletia Tritici (Bjerk.) Wint. This species was re- 

 ported by Pipal in 191.5.^" Further examination shows that the 

 specimen on which the report was based was mislabeled, the 

 species really being Ustilago Tritici (Pers.) Jens.
