440 OHIO EXPERIMENT STATION: BULLETIN 214 
For control of the disease thorough separation of all the light rye kernels in 
the seed. and subsequent seed treatment are recommended. (See Bulletin 203). 
Fig. 90. On the left kernels of rye shriveled from an attack of - 
anthracnose; on the right, normal, healthy kernels of rye. From Bulletin 
203. 
Ergot occurs occasionally in rye; the fungus ( Claviceps purpurea (Fr.) Tul.) 
attacks the kernel and transforms it into a large club-shaped dark mass, the 
ergot of the druggist. The amount of ergot is usually not enough 'to be aserious 
trouble in our state. Ergotism in domestic animals is sometimes caused when 
' diseased rye is fed to them. : 
Rust. The species of rust which occur upon wheat are also found upon rye, 
(See wheat). 
Scab. The scab (Fusarium roseum Lk.) as is shown by recent work at this 
Station attacks rye almost as freely as wheat. The fungus in question is shown 
by recent work to be the same as that in wheat. The remedy is the same as that 
recommended for anthracnose. 
Smut. The fungus ( Urocysts occulta Wallr.) of stem and blade smut in rye 
occurred at this Station in 1909. It attacks the culms, leaves and leaf-sheaths 
but not commonly the floral parts. The smutted parts swell and burst open in 
elongated lines. Seed treatment may reduce this smut but hardly prevent it 
altogether. 
SALSIFY 
White Rust (Albugo tragopogonis Tul.) attacks this plant and is sometimes 
destructive. The best results seem to be promised by avoiding sources of infec- 
tion and by spray treatment. 
SORGHUM 
' Bacterial Blight of sorghum is somewhat similar in its general appearance 
to the bacterial blight of corn already described, and is caused by a specific 
organism (Bacillus sorghi Burr.). It has been described in the Kansas Experi- 
ment Station Report for 1888. 
Grain Smut (Cyntractia Sorghi-vulgaris (Tul.) Clinton) attacks the seed of 
the sorghum plant. The hot water treatment may be adapted to prevent this. 
Head Smut (Sphacelotheca retliana (Kuhn) Clint.) occurs occasionally where 
sorghum is grown, but is less common than grain smut. 
SOYBEAN 
Wilt occurs in most districts where soybeans are grown. We have had very 
few reports in Ohio.. Indications show that the one most likely to occur is that 
due to a wilt fungus (Fusarium).
