These directions cover the main
points in spraying against the com
mon insects and diseases Of the apple,
peach and cherry.
The Apple Tree.
FIRST SPRAYING: Just after the
first clusters of leaves have opened,
but before the blossoms themselves
have u~nfolded, using either Bordeaux
mixture three pounds copper sui
phate, three pounds lime, so gallons
water) or commercial lime sulphur,
Ia gallons to Ash gallons of water.
This spraying is chiefly for the pur-
pose of controlling the apple scab dis
ease, which causes so many specked,
knotty apples.
SECOND SPRAYING: Immediate
ly after the majority of the blossoms
have fallen, using commercial lime
sulphur. III gallons to 4Sh gallons of
water, Before filling the barrel with
water, add three pounds of arsenate
of lead paste to poison the insects.
Stir the paste thoroughly in a bucket
Of water before pouring into the
sprayer, as otherwise it would sink to
the bottom of the barrel in a lump.
This spraying Is to prevent the apple
scab- and is the a~ll-important applica-
ton for controlling the coddling moth
and curculio, the two worst insects of
the apple.
THIRD SPRAYING: Two to three
weeks after the blossoms fall, using
either Bordeaux mixture or lime sui
phur as directed under first applica-
ton. Also add az pounds of ~arsenate
of lead paste. This spraying is for
the purpose of poisoning the curculio
and codling moth insects and prevent
ing apple scab, apple blotch, black rot
and other diseases.
In north Missouri three sprayings
will usually be sufficient. In south
Missouri, were there is danger of bit
ter rot, two or three additional spray
ings will be necessary. The fourth
application should be given six weeks
after the blossoms fall, using Bor-
deaux mixture 4-4-50 or $3.50, and if
there are signs of a late brood Of
cooling moth add az pounds Of ar
senate of lead. Other sprayings may
be given at intervals of two weeks,
using only Bordeaux mixture at the
rate of $780, Lime sulphur is not
reliable for preventing the bitter rot.
The Peach Tree.
FIRST SPRAYING: A few days
after the blooming period, when the
calyx tube or "shuck" Is just drop
ping off of the little peaches, spray
with ~arsenate of lead paste two
pounds, lime four pounds, water so
gallons. (Slake the lime, mix the ar,
senate with water and pour in, then
add water to make so gallons.)
SECOND SPRAYING: Three weeks
after the first application, use arsen-
ate of lead paste III pounds, the
Scott self-boiled lime sulphur $3.50.
This kind of lime sulphur n be
bought, SO it must be made at home.
Stake eight pounds OF lime in a box
or large vessel. When it begins to
simmer from its own heat stir in
eight pounds of fine sulphur. Stop
the simmering or boiling at the end
of eight or ten minutes by pouring on
cold water. Strain the mixture into a
barrel and add water to bring up to-
80 gallons.
Peaches are sprayed in order to
prevent the brown rot, which destroys
the fruit at near ripening time. To
aid in preventing the rot it is neces-
sary to poison the curculio insect,
which is responsible for spreading the
disease.
Sometimes a third spraying will be
necessary. This should be made one
month before the fruit is ripe, with
lime sulphur $3.50. 1t is
not necessary to add any poison. The
commercial lime sulphur, eve when
diluted, is not safe for spray
ing peaches, as it is liable to cause
to both fruit and foliage.
The Cherry Tree.
FIRST SPRAYING: After the
leaves have begun to come out, but
before the blossoms open, using Bor-
deaux mixture $3.50 or some form of
lime sulphur, either the commercial
or self-boiled.
SECOND SPRAYING: AS soon as
the calyx tube is off of the young
use ~arsenate Of lead paste two
pounds, Bordeaux mixture $3.50 or
lime sulphur 1880, or COM
.ercial lime sulphur IN gallons, with
water enough to make up to 30 gal
Ions Of the solution.
These two ~sprayings are to control
the leaf spot, powdery mildew and to
the curculio insect, which
punctures the fruit.
THIRD SPRAYING: Just after the
fruit is off, using Bordeaux mixture
$3.50, self-boiled lime sulphur 1850
Dr. commercial lime sulphur ~ gal
Ions to 48h gallons of water. This 10
10 make healthy foliage in order that
good strong fruit buds may be formed
Tor the next years crop.
