Fiisariimi Blight of the Soy Bean 9 
E). Wilt of cowpeas and blight of soy beans were present on the 
farm of one of the correspondents previously referred to, at Eed 
Springs, N. C. Many ’of the soy bean plants in this field were 
killed and many only stunted, so that a decrease in yield of 60 per 
cent during the season of 1916 is probably a correct approxima- 
tion of his loss. Blight of soy beans has also been found to occur 
at Exum and BelhaA^en, hi. C., and was the cause of considerable 
loss in both locations. The first of these soils occurs in the eastern 
edge of the Piedmont and the others in the Coastal Plains section 
of the State. 
Dr. W. H. Tisdale, in coiwersation with the writer in 1917, 
said that while at Madison, AYisconsin, his attention was called 
to diseased soy beans growing in experimental plots which seemed 
to be infected with a species of Fusarium. Upon being shown 
specimens of the soy bean blight, he stated that the diseased 
plants looked very similar to those he had previously seen. 
Dr. G. L. Peltier wrote from the Alabama Experiment Station in 
the fall of 1917 : “It (soy bean blight) was quite coimnon here 
on the station farm, and I isolated a Fusarium from the infected 
material.” 
Cowpea-Avilt has been found in many localities in parts of 
the United States. It is also entirely probable, if we judge from 
the results to be presented subsequently, that the soy bean-blight 
may appear more or less generally wherever the soil is infested 
with Fusarium tracheiphilum, Kecords received from the office of
