38 ROBSON QUALITY SEEDS, HALL, NEW YORK 

Lee Tichenor has just finished picking up a bushel of Certified Ontario Seed Potatoes. In spite of the dryest Summer that we can 
remember, this field yielded over 650 bushels per acre. Inspection report showed only 2/10 of 1% leaf roll—no other disease. 
CERTIFIED SEED POTATOES 
1 Peck (15 lbs.) will plant about 200 ft. row 
Certified seed potatoes are grown from carefully selected tested certified stock; officially inspected in the field 
for trueness to name, for disease and insect damage, harvested and again tested in Florida to insure our customers 
of the highest quality seed that can be produced. Each bag carries a certificate stating that the contents meet 
certification standards. 
Irish Cobbler has for years held the reputation of being the best quality early potato for both home use and 
market. We have found that Certified Cobbler seed grown on Prince Edward Island, Canada, will yield more 
bushels per acre than is possible from seed grown farther South. 
Bliss Triumph is a very early pink-skinned variety. Bliss does not usually yield as well as Irish Cobbler 
but is earlier. 
Katahdin and Chippewa are comparatively new midseason varieties that have found favor in many localities. 
The new Ontario has created wide interest in the whole Northeast. Ontario not only yields well, but is very 
resistant to Potato Scab. 
Essex is a new blight resistant potato that is not only highly blight resistant but also yields very well. 
NEW YORK CERTIFIED ONTARIO: 120 days. 
Ontario is a seedling resulting from a cross made by 
the U. S. Dept. of Agriculture. Our farms are in 
the limestone belt of New York State where the soil 
is favorable for the development of potato scab. In 
fact, we have been forced to grow our New York 
Certified seed in other areas of the State where potato 
scab is not a problem. 
Some years ago we set up a scab testing plot on 
one of our farms in cooperation with the New York 
State College of Agriculture. Here on the same 
scab infested land year after year various new varie- 
ties of potatoes were tested for resistance to scab. 
Ontario was outstanding and also had what manv 
others did not have—fair to good cooking quality and 
yield. Ontario has been tested in many other places 
and we are sure that it will do much to solve the scab 
problem in those sections that are affected. Ontario 
comes out clean where other varieties fail. 
Ontario tubers are very smooth, shallow-eyed, 
white and slightly elongated; not only very resistant 
to scab but quite resistant to late blight and “‘Z”’ 
disease. 1 peck (15 lbs.) by Parcel Post $1.95; pre- 
paid; 1 to 10 bags $5.50 per 100 lb. bag; 10 to 50 bags 
$5.35; 50 bags or more $5.25. not prepaid.

Orson says, “Ontario can be planted on soil badly infected with 
scab and will come out clean at digging time.”’
