edges of the leaflets. At the end of
ten days to two weeks, half of the leaf
surface may be brown, withered, and
brittle, while the rest is of a yellowish
green color. Three weeks or month
may elapse before all the leaves sue
cumb. The stem in the meantime re-
mains green, but they too finally per-
ish through lack of nourishment. The
tubers stop growing almost as soon
as the leaves are attacked, and as a
result the crop is practically worth
less.
Early blight may be held in check
by the application of the fungicide
Bordeaux mixture. This is prepared
and applied as follows: Pour into
fifty gallon barrel twenty-five gallons
of clean water; then weigh out six
pounds of crushed bluestone, or cop
per sulphate, and after tying it in
piece of coarse sacking suspend the
package just beneath the surface of
the water with string tied to stick
laid across the top of the barrel. In
another suitable vessel, such as tub
or half barrel, slack four pounds of
fresh lime. Slack the lime carefully
by pouring on small quantities of
water at a time, the object being to
obtain smooth, creamy liquid, free
from grit. When the lime is Stacked
add sufficient water to make twenty
five gallons. AS soon as the blue
stone is dissolved, which will require
an hour or more, pour the lime milk
and bluestone solutions together, US
ing separate barrel for the purpose
and stirring constantly to effect a
thorough mixing. It sometimes hap
pens that sufficient lime is not added,
and as a result the foliage may be
injured. To be certain that the mix
ture is safe, hold steel knife blade
in it for two or three minutes, and if
the polished surface or the blade
shows copper-colored tinge add more
lime, but if it stays bright the mix
ture is safe to use. Application of the
mixture should begin when the plants
are four to six inches high, and should
be repeated at intervals of twelve or
fourteen days until five or six treat
ments have been made. By adding
eight ounces of Paris green to each
barrel of the Bordeaux mixture CON-
bined fungicide and insecticide is OBJ
tanned, this will prevent the attacks of
the Colorado potato beetle, the flea
beetle, and other insects. Before add
ing the Paris green it should be mixed
with a small quantity of water, and
when a thin paste is obtained this
should be thoroughly stirred into the
barrel of the Bordeaux solution.
The success attending the applica-
ton of the Bordeaux mixture depends
in large measure upon the thorough
ness with which it is applied. To
reach all parts of the paints above
ground with fine spray requires
good force pump and suitable noz-
zle. The knapsack sprayer, now on
sale in nearly every section of the
country, will be found one of the most
useful machines for spraying fields of
three acres or less. For larger plant
ations more powerful machines should
be used. A cheap and serviceable ap-
paratus, we'll suited for this work, NAV
be made by mounting good, strong
force pump on barrel, and then plac-
ing the barrel and mounted pump in
light wagon. The entire outfit, in
Guiding barrel, pump, hose, nozzles,
operator, and boy to drive, may be
drawn by one horse. AS the wagon is
drawn slowly between the rows the
man in the wagon may operate the
pump and at the same time keep the
mixture stirred, while two others on
the ground hold the nozzles and direct
the spray over the plants. The nozzle
found to be best suited to the work is
the Vermorel. This is now offered
for sale by pump manufacturers and
dealers in seeds and agricultural i'm
plements in various parts of the coun-
try. Where there are only a few
plants to treat, simple devices for the
application of the fungicide, such as
watering cans, the syringes used by
florists etc NAV no mood
There would appear to be some
difference of opinion as to the plant
ing of potatoes on ground where there
was potato rot or blight last year, but
the safer way would be to use new
ground this spring and take no
chances.
