ADDENDUM 
Corn, Root-Rot, (Fusarium sp.). Recently the Department has made pre- 
liminary studies of a root-rot of corn attributed to a species of Fusarium of 
similar behavior to the scab of wheat, potato fusarium and cabbage wilt, in 
that the parasite appears to survive in the affected soil, as well as elsewhere. 
From Fayette county comes the report of diseased corn roots in patches where 
the stalks blow over easily, and rarely form mature ears. Roots of such plants 
are partly killed and thus weaked. At present we can only advise rotation of 
crops. More knowledge is needed with all this type of soil infesting diseases. 
Raspberry, Cane Blight (New York). In reference to cane blight conditions, 
page 437, this specific disease described by Stewart (Bul. 226, N. Y. Agric. 
Expt. Sta., 1902) was not mentioned. Stewart identified the disease on speci- 
mens sent to him from Ohio in 1902. Recently other specimens have been received’ 
from Cuyahoga and Wood counties. The earlier reference to cane blight forms 
indicates how serious the raspberry condition is in Ohio. The parasite causing 
the disease is Coniothyrium Fuckelii Sacc. The fungus attacks the plants kill- 
ing and discoloring the bark and wood, thereby causing wilting of bearing 
canes, and the ultimate death of the parts that have been attacked. The foliage 
on affected canes wilts suddenly and becomes dry. The whole cane may be 
involved, or only a part of it. At times a single branch is killed, while the 
remaining cane continues apparently normal. It is feared that this disease is 
very common in our unprofitable raspberry plantations in Ohio. The disease is 
doubtless disseminated in plants from diseased plantations, and by the ordinary 
agencies of wind, rain, etc. Naturally the dissemination by these last two 
agencies is local. Preventive measures will include healthy plants, planting 
on new uninfected land and a prompt cutting out and burning of old canes after 
fruit is gathered. Stewart’s work indicates inconclusive results from spraying.
