One of the most dangerous diseases of Irish potatoes, potato 
wart, has been discovered in the United States. Rough, spongy 
outgrowths of varying size are produced on the tubers, especially 
at the eyes. These warts are light brown at first, but become 
black and decayed with age. Sometimes all potatoes in affected 
hills are worthless. The disease does not attack the vines above 
ground. Prof. H. M. Fitzpatrick and Dr. L. R. Hesler of Cor- 
nell University were appointed special field agents of the Federal 
1e effort to locate this 
disease. They spent the past summer in a survey of New York 
— 
Plant Disease Survey in connection with t 
State. It is believed that the great bulk of the infested potatoes 
were distributed from the port of New York.
