of giving accurate and timely information regarding control measures; 

 and by propaganda to convince farmers of the desirability of adopting 

 such measures. 



Demonstrations in the control of potato diseases, on potato cars or at 

 farm bureau meetings, were held in seventy-eight localities, representing 

 thirteen counties. Under the New York State Food Supply Commission, 

 inspection of potato fields in order to secure good seed for 191 8 was made 

 by two inspectors in thirteen counties, and as a result 923 acres of potatoes 

 good enough to pass two inspections were located and listed. Seven 

 county field assistants were placed in eight counties, with the result that 

 over 5100 acres of potatoes were sprayed more properly than could have 

 been done without this service. 



Fourteen demonstrations in the control of fruit diseases were held in 

 seven counties. Nine counties had field assistants receiving supervision 

 from this Department. Five of these assistants were hired on funds 

 of the State Food Supply Commission, and the others from various other 

 funds. Eleven of the important fruit counties received some assistance 

 from this Department. 



Twenty-nine demonstrations in the control of oat smut were held in 

 five counties. In addition, two counties had the services of two federal 

 demonstrators working in cooperation with the College of Agriculture, 

 by whom twenty-five demonstrations for the control of wheat smut were 

 given. 



Fourteen lectures, inspections, or demonstrations in the control of 

 diseases of other crops were held in twelve counties. 



Fifty-two persons, from forty-five counties of the State, reported plant- 

 disease conditions in their counties or communities to this Department, 

 where the results were tabulated and the information was made available. 

 By means of this survey the Department was able to determine the earliest 

 appearance, distribution, and severity of the various plant diseases, and 

 to direct control work accordingly. This work was done in cooperation 

 with the Plant Disease Survey of the United States Department of 

 Agricultiire. 



Six exhibits at state and county fairs, at state fruit meetings, and at 

 the Rochester Exposition, were made during 191 7. In addition to these 

 a potato-disease exhibit was carried on the potato car. 



Work was given at thirteen extension schools, representing eleven 

 counties. 



In addition to four persons regularly employed in extension activities, 

 eight members of the staff assisted in some regular work. The State 

 Food Supply Commission employed thirteen field assistants, two potato 

 inspectors, and one stenographer from the Department, for plant-disease
