WHAT IS CERTIFIED SEED? 
WISCONSIN CERTIFIED STOCK is your guarantee of quality seed. The 
seed fields must be inspected at least twice while growing in the fields by an 
official State Inspector and again in the bin after being dug, and both times 
pass the necessary requirements, The fields must be sprayed for disease 
on the order of an official inspector, The stock must be practically 100% 
pure in type, must be free from late blight rot, blackleg, powdery scab, leaf 
roll, tuber moth, Sclerotium Rolsfii Wilt, potato wart, ring rot, brown rot, 
and conform reasonably to the correct vine and tuber characteristics of the 
variety. The seed used in planting the crop must be proven certified 
seed that has a history starting from carefully selected plants, true to type 
and free from mixture. Complying with all the above réquirements, the pota- 
toes are eligible for certification and are placed in official branded bags 
and sealed with official tags. In less than full bags, orders are filled in our 
bags and with our labels. Field and bin inspections are made by the Wis- 
consin College of Agriculture and final pack inspections by the State Depart- 
ment of Agriculture.

f. o. b, Madison, Wisconsin. Bags are free. 
Early Irish Cobbler seems to continue to increase in popularity. People like a 
white potato. It is famous now the country over. At first it was largely grown for 
the early market by the truckers of New Jersey and Virginia and other Atlantic coast 
States. From there its popularity has extended throughout the whole of the United 
States and it is a standard, well-known variety now nearly everywhere. 
It is a pure white potato, nearly round in shape with eyes rather more pronounced 
than He the Early Triumph, It usually outyields Early Triumph although not quite 
as early. 
The potatoes are very attractive looking and of most excellent quality, rather ahead 
of all other earlies in that respect, always cooking up dry and mealy. This variety 
will please anyone who wants a few earlies for home use as well as the large grower 
and the market gardener.

A late potato introduced and released in 1937 by the United 
States Department of Agriculture at the Potato Breeding Station at 
Presque Isle, Maine, from a cross between Chippewa and Katahdin. Dur- 
ing a period of about five years, prior to its introduction, it exhibited 
remarkable resistance to late blight tuber rot caused by one of the 
most serious Potato diseases, known as Phytophthora Infestans which 
was the disease that caused the crop famine in Ireland in 1845. 
From 1938 to 1941, the Wisconsin College of Agriculture carried on 
extensive tests in nine different Potato-producing counties. These years 
the blight was unusually severe, but Sebago showed only 5% Blight 

Early Triumphs, 
EARLY TRIUMPH 
Triumph is a standard extra early. It is a variety grown in tremen- 
dous quantities in northern Wisconsin for seed and shipped to the south- 
ern growers in the Fall who grow them during the Winter months and 
supply the first early new potatoes on the market, A heavy yielding va- 
riety in northern Wisconsin, but is inclined to yield light in the southern 
part of the state. Potatoes are nearly round, light red skin, moderately 
shallow eyes and always cook mealy and white, :

TREAT POTATOES WITH SEMESAN BEL. 

For better yields treat seed with Semesan Bel, 
Only 0.4 bushel of the average yield increase of 35.4 bushels were 
required to pay for the Improved Semesan Bel, leaving a return of 9,830 
per cent on money invested! 
Tests in 15 states have proved that most potato growers can usually 
expect better returns from seed potatoes if they treat them with Seme- 
san Bel, Costs only about 21¢ an acre—generally reduces seed-piece 
decay, seed-borne scab and Rhizoctonia. No mussy soaking—after cutting 
just dip, drain, dry and plant! One pound treats 60 to 80 bushels of 
seed. Prices: 2 oz., 35c; 1 1b., $1.83; 4 lbs., $6.33. By express or freight 
f. 0. b. Madison: 40 lIbs., $59.00; 100 lbs., $138.75. Sizes and prices

Tuber Rot whereas the other standard sorts showed as high as 75 to 
85% tuber rot. Recent tests also show that this variety is highly 
tolerant to Potato Hopperburn caused by the Potato Leaf Hopper. Wis- 
consin College of Agriculture Potato Specialists have found the Sebago 
is definitely resistant to the Yellow Dwarf disease which often causes 
heavy losses in the sandy soil regions of Wisconsin, Michigan and Min- 
nesota. Its yielding ability is about the same as Russet Rural or Cobbler. 
Cooking tests show the variety to cook up white where under the same 
conditions standard varieties cooked black, 
The tubers are very similar to Chippewa—white, thin skinned, shallow- 
eyed, and oval to oblong in shape. Vines are large, definitely upright 
in growth habits. During hot weather it has a tendency to roll its 
leaves which cause it to resemble the Leaf Roll Disease. This, however, 
has no connection with the disease. In season it is definitely a late 
potato. It sets its tubers several weeks earlier than Rurals, but the vines 
remain green just as long and sometimes longer. Because of its fine 
quality and thin skin, it is quite susceptible to Scab. Plants set heavy 
with tubers and therefore it requires a fertile soil.
