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 a 
heavy yielder. 
We recommend it to Wisconsin 
potato growers as it is earlier 
than Green Mountain and other 
late potatoes and is a handsome 
potato and a heavy yielder. The 
skin is velvety white, has shal- 
low eyes and is oblong in shape. 
Since we first introduced this 
potato in 1936, our sales have 
greatly increased each year. Sel- 
dom has hollow hearts and always 
cooks up white.

RUSSET RURAL 
In appearance, size and yield, the Russet Rural is very similar to the 
White Rural New Yorker, the only difference is that the skin is slightly 
‘yusset and tubers in shape are more flat and a trifle shorter. Growers 
claim that the Russet has a little better quality than the White, and are 
more popular on some markets. An old variety that is losing its popu- 
larity rapidly to the new Chippewa and Blight Resistant Sebago varieties. 
Resistant to Hopperburn. It sometimes cooks up dark. The shallow 
eyes and attractive appearance make it popular on the market, but it 
is largely grown because it yields heavily and is quite resistant to scab.

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 tend- 
ency to come up 
through the soil and 
sunscald. The vines 
seem quite resistant to 
Hopperburn. Probably 
the best keeping va- 
riety on our entire list.

INSECT 
CONTROL 
We recommend Red 
River Potato Mix as an 
ideal all-purpose spray 
for the control of in- 
sects and fungus dis- 
eases on potatoes. It 
can be used as a dust 
or spray. Drives off the 
flea beetle and leaf 
hopper; prevents 
blight, and kills potato 
bugs quickly. Order 
some of this material 
to be shipped with 
your potatoes. See page

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 and is being used extensively by potato plant breeders. Devel- 
oped by Professors Wayne Weber and Henry Darling and Dr. Gus 
Reimann at the Wisconsin College of Agriculture. It is essentially 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 with 
shallow eyes. The tougher Russet skins give this strain more resistance 
to scab than its parent, the smooth, thin skinned Sebago. If you have 
scab infested soil you should plant this new variety. We consider Russet 
Sebago superior to the Russet Rural, which formerly was our best variety 
on scab infested soil. Seed stocks are likely to be short, and we advise 
you to place your order early to be sure of seed.

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 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 
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 Oollege 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.
