CHIPPEWA 
The heavy yielding 
midseason potato 
A midseason or second early 
potato introduced by the U. S. 
Department of Agriculture which 
in trials has proven outstanding 
for the northern states. It is 
resistant to mild mosaic and is a 
handsome potato and a heavy 
yielder. The skin: is velvety white, 
has shallow’ eyes and is oblong 
in shape. Seldom has _ hollow 
hearts and. always cooks up 
white.

ey ONTARIO 
Most Scab Resistant Variety 
Ontario is the most scab resistant variety grown in America at the 
present time. It is a high yielding late potato which: was introduced 
by the Cornell Agricultural Station in 1944. Tubers are smooth, white, 
and slightly elongated, and of. good cooking quality. It produces a 
remarkably high percentage of tubers that will grade U. S. No. 1 quality. 
As Ontario is twice as resistant to scab as the old Russet Rural, which 
was grown primarily because it was scab resistant and is of much better 
cooking quality, we are discontinuing the Rurals in preference to the 
new Ontario. Plants are medium to large, erect, ‘and spreading. Very 
late maturity. Growers who have scab in their soil will make no mistake 
by planting this variety. Prices, Wisconsin Certified Stock, by freight

KATAHDIN 
Heavy Yielding Late Storage Potato 
Katahdin is one of the higher yielding late varieties, which is 
generally adapted to Wisconsin growing conditions. It was developed 
by the U. S. Dept. of Agriculture at Presque Isle, Maine. It is a 
heavy yielder, resistant to mild mosaic, tolerant to heat and drought con- 
ditions, but extremely susceptible to scab. On ‘scab-free soils it pro- 
duces beautiful white tubers of high market quality. The. potatoes are 
very similar in shape and appearance to Chippewa. The skin is velvety 
white, very shallow eyes, oblong and somewhat flat in shape. On light 
soils the tubers have a tendency to come up through the. soil and sun- 
scald. The vines seem quite resistant to Hopperburn. Probably the 
best keeping variety on our entire list. p

SPROUT-LOK 
. Stops Sprouting in 
Storage 
A chemical that when 
dusted over potato tu- 
bers when they are 
placed’ in storage in 
the fall at the rate of 
12 ounces. to nine 
bushels will keep them 
from sprouting, The 
harmless chemical va- 
porizes and comes in 
direct contact with the 
potato eye. Not effec- 
tive -if applied~ after 
the tubers have sprout- 
ed. .Spread the tubers 
in ‘layers and dust the 
tubers. as they are 
loaded into the bin or 
‘dust cellar. through a 
chute. Do not use on 
seed potatoes.

Russet, Sebago is scab free grown on scab infested soil, 
RUSSET SEBAGO 
Scab and Late Blight Resistant 
This variety is resistant;to more potato diseases than any other 
variety. Developed by Professors Wayne Weber and Henry Darling and 
Dr, Gus Reimann at the Wisconsin College of Agriculture. It is essential- 
ly the Sebago in a Russet skin. Like Sebago it is resistant to late 
blight, is a heavy yielder, cooks up white, and the tubers are well shaped 
The tougher Russet skins give this strain more re- 
sistance to scab than its parent, the smooth, thin skinned Sebago. If you 
have scab infested soil you should plant this variety or Ontario, Russet 
Sebago is not quite as scab resistant as Ontario, but in addition it is 
blight resistant. :

RUSSET BURBANK—IDAHO 
In Wisconsin, generally speaking, this variety does not yield good, 
but on some muck soils and“in some areas it has done very well. On 
the market it is generally sold as Idaho Russet, and is one of the best 
potatoes for baking. The Oblong potato has a well netted brown skin, 
and the eyes are shallow. Prices: Wisconsin certified stock by express or

SEBAGO 
Late Blight Resistant Potato 
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 causéd the crop famine in Ireland in 1845. 
It is highly tolerant to Potato Hopperburn caused by the Potato Leaf 
Hopper and is definitely resistant to the Yellow Dwarf disease which 
often causes heavy losses in .the sandy soil regions. 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 vari- 
eties cooked black. =f 
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. Duripg”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.
