In some useful suggestions as to
spraying the Rhode Island station says
The most serious disease affecting the
potato is commonly known as the late
blight, and is caused by the growth
within the leaf tissues Of a fungus,
which may often be seen on the under
side Of an affected Leaf as a delicate
white mildew hence often called
potato mildew. Its first appearance
is denoted by brownish or purplish
black spots on the leaves These spots,
under the favorable conditions Of warm,
moist weather, spread very rapidly,
soon involving the entire plant. which
becomes black and dropping and de-
Gays rapidly, emitting peculiar, dis
agreeable odor. 4 .%4s .j65.sa
EARLY blight, sometimes called the
''''leaf spot disease, more especially
affects early potatoes and is also caused
by q fungus. It may be recognized by
the appearance of small spots on the
leaves, which slowly enlarge, forming;
irregular, concentric rings. The foliage
dies prematurely. but1does not decay.
nor do the tubers, as when affected by
the late blight. Yet if largely prevalent.
the disease very seriously affects the
yield not only in quantity, but in quail
ity. Tip burn is not caused by fungus,
as are the blights, but by unfavora-
BILE conditions affecting the growth Of
the plant, especially dry, hot weather
and lack of sufficient moisture.
As both the early and late blighta
are caused by fungi, the surest and
most perfect protection yet known
ia the bordeaux mixture. This should
be applied before the. early blight
makes its appearance, and the applica-
tions continued, as necessary, to keep
the plants covered with thin film Of
the mixture until the tubers are grown
and matured. It should be borne In
mind that the correct idea in the use Of
the bordeaux mixture Is prevention
rather than cure.
The spores Of these fungous diseases
as they fall upon the foliage protected
by the mixture are prevented from en-
tering the host plant by the film of cop
per compounds and thus prevented from
propagating the diseases.
Three to five applications will per-
haps be sufficient, yet the weather con-
ditions must govern the number Of
treatments. as, if heavy showers or
rains occur, extra sprayings may be
necessary to keep the plants well pro-
tected.
In the case of the late blight, Sc
lecting seed from fields that were free
from the disease and planting tubers
entirely free from infection are sug-
gested as checks. to tho disease. The
spores of this disease live over winter
in infected tubers; hence, II such are
planted, they may become centers Of
infection by introducing the disease.
I Tip burn can only be combated by
thorough preparation. proper fertiliza-
tion. conserving the moisture in very
dry seasons by proper cultivation, and
making every condition favorable for
early, vigorous growth, thus giving
more power to Withstand the attack Of
disease. .r4 /. .'. -ty
