Fvsarium Blight of the Soy Bean T 
bushel of corn. Soy bean hay contains 2.48 per cent nitrogeiij 
0.40 per cent phosphoric acid, and 1.32 per cent potash. 
It has been found in most of the soy bean growing sections of 
the South that an acre will produce on the average something 
like two-thirds to three-fourths as many bushels of soy beans as 
of corn and the price brought by soy beans has always been 
from 50 to 100 per cent greater. 
During 1915, $9,000,000 worth of oil alone was imported. 
Cottonseed oil mill owners have been induced, however, ^^artially 
by the efforts of members of the staff of the North Carolina Ex- 
periment Station, to crush soy beans during their otherwise idle 
season. The few mills in the State which have done this have 
found a ready market for the oil and meal. 
OTHER SOY BEAN DISEASES 
So}^ beans are very generally observed to be quite free from 
disease, and no very seriously destructive parasites of this host 
appear to have been reported in the literature at hand. Of those 
reported, a detailed study has not been made, except in the case 
of Bacillvs lathy vi Manns and Taubenhaus (16, 17). The accounts 
of the other diseases consist of brief fragmentary mycological 
notes and mention of their place of collection or of their appear- 
ance. Since any of them may appear on plants affected with’ 
blight or wilt, it is deemed advisable to call attention to the pub- 
lished accounts of these diseases and the appropriate bibliography. 
Septoria sojina v. Thiimen (on living or declining leaves) (27). 
Phyllostica sojaecola Massalongo (18, p. 688). 
Aecidium glycines P. Henn. (8, p. 52). 
Uromyces sojae (P. Henn.) Sydow (25, p. 429). 
Bacillus sp. (on leaves) — Heald (11, 12), Smith (24), and Clinton (4). 
Bacillus lathyri Manns and Taubenhaus (on leaves and pods) (17), 
and Manns (16). 
Heterodera radiciola — Scofield (22, p. 9), Gilbert (10, p. 9), Bessey 
and Byars (2, p. 8). (These authors merely mention the soy bean 
as a host for this parasite.) 
Chlorosis and crinkling (cause?). (Description of the disease in the 
.field.) Clinton (5). 
Septoria glycines T. Hemmi (comparison with sojina above) (13). 
A disease due to Sclerotium rolfsii is the only one not re- 
ported which the writer has observed to seriously injure the crojD. 
It is not believed that the presence of any of these organisms 
would lead to confusion in the diagnosis of blight caused by the 
species of Fusarium under consideration.
