CHARD PESTS
Timely Formulas for the Guild
ance Of Fruit Growers from
Reliable Authorities.

I The State Board of Horticultural
Inspection has issued the following
instruction and formulas for spray
Y ign for the guidance of orehardists:
i Spraying for fruit diseases is pre-
ventative rather than curative. The
work Of prevention should begin in
the dormant season when strong rem
edies may be used to destroy the
spores or germs. For all fungus dis
eases there is no better remedy in the
dormant season than Remedy No. l
given below; and for spraying
for fungus diseases when plants are
in leaf, al things considered, the
Bordeaux mixture has been found the
most effectuaL
/ Remedy No. 1.
To be used in the dormant season
for scale, pear leaf blister mite, aphis
eggs, etc, or fungus diseases of any
kind.
Formula-Sulphur 20 pounds, un-
Stacked lime 40 pounds, water so gal
Ions. For a greater or less quantity
the ratio would be l pound salt, 2
pounds sulphur, pounds lime to ey-
cry gallons water. This mixture is
seldom used now, the manufactured
preparation taking its place.
Panadv M .
For codling moth, or leaf eating
insects.
Formula -Arsenate Of lead ) to 6
pounds, water 1OO gallons.
Bordeaux Mixture.
For fungus diseases, TO be used in
the summer time
Formula Water so gallons, copper
sulphate pounds, unslaked lime 4
pounds.
Directions Dissolve S pounds of
copper sulphate (bluestone) in a
wooden vessel to prevent corrosion OF
metal. 1t dissolves most readily IN
not water. Add several gallons Of
water. Reduce 4 to pounds of good
lime, that which has not been air
Stacked, TO a lime milk, by the slow
addition of water and constant str
ring with hoe. Add several gallons
of water. Strain both bluestone, wa
ter and milk of lime through a wire
screen into common wooden tub, mix
carefully with hoe, until pretty
blue mixture is the result Pour this
mixture into your spray barrel, add
water enough to make 10 gallons IN
all, stir well with hoe, or with an
stirrer in the barrel, when
the mixture is ready for use
The proper time to spray for San
Jose scale is in the dormant season
using the ine-sulphur solution
The codling moth, or apple worm, is
a familiar pest to every grower or
consumer of apples. The arsenste of
cad formula is the proper spray. The
first application should be made when
the calyx is open. The second, 10
lays after the pupae change to moth;
he third, % days after the first worm
appears, to be followed two weeks
ater by the fourth spray.
Peach Twig Borer.
1t has been observed that where
the lime and sulphur solution has
Jeen used for scale it has very mater
ally reduced this pest. All other
recommended methods of control, such
Is spraying with arsenicals and cut
ing the infested twigs, have been
'ound inadequate The lime and sui
thur spray applied in the dormant
season will not entirely eradicate the
,orer, but will reduce its numbers to
he minimum, and this method is un-
lualifedly recommended as the only
PRACTICAL remedy.
Pear and Cherry Slug.
While the pear and cherry slug Is
cry easily controlled with an appll-
alton of arsenic, it so happens that
With cherries 1t appears Just ABOUT
licking time, when it is not desirable
o spray. as this would cover the fruit :
nth spray and injure its appearance
or market. The slug is now found IN
II fruit sections and can be expected
o appear nearly every year, ana
therefore, any grower having cherry
rees should spray with an arsenieal
pray at least month before picking
ime, thus having the poison ready
Or the insect without injury to the
ruit. The pear and ounce can De
prayed at any time. If only few
-ees are in the orchard, frequent ap-
lications of fine road dust, ashes or
lr Stacked lime are effective, as such
distances adhere to the insects and
ry them up.
