SPRAY MIXTURES FOR GARDENS
By AMDREWM. eSOOZE

What are the best materials to use
as spray mixtures? How should
they be prepared and applied? These
are inquiries which are received al
most daily. Naturally, this knowl-
edge is matter of grave Importance
to the gardener because it represents
the only means available to him of
successfully controlling most plant
and insect diseases. Therefore, it
seems desirable to give this informa-
ton in as much detail as is possible
so that all who are interested in pro-
tecting their gardens may have the
essential data at their command in
a concise, up-to-date and accurate
form. 1t is of the utmost impor-
lance, especially to the uninitiated,
that the directions set forth be fol-
lowed with the greatest skill and
care. The materials to-. be used in
making up spray mixtures should be
bought under guarantee because if
they fall below the standard the
chances are they will prove ineffec-
tive and their use may even result IN
loss rather than benefit. The scien-
fists of the experiment stations and
colleges of the United States have
spent a great deal of time and effort
on work of this character, and the
data presented is the best informa-
ton extant along the line indicated.
I feel that our readers. can follow
the advice given with highly bene-
fetal results.
Arsenate of Lead. This is prob
ly the most serviceable and the
least harmful to plants of the
arsenical sprays for biting insects:
Two pounds arsenate of lead paste
or one of powder, two pounds of
quick lime. fifty gallons of water.
Stake quick lime and make up to
fifty gallons with water. If pow
dered arsenate of lead is used make
one pound into a paste with water.
to the fifty gallons. Thoroughly stir
until it is all in uniform suspension.
Strain to remove Jumps of lime and
apply with spray pump.
Paris. Green Four ounces Paris
green, four ounces quick lime, fifty
under arsenate of lead. Use arsenate
of lead in preference to Paris green,
on cantaloupes and other vine crops,
as the Paris green is more apt to in
Jure the plants than the arsenate
of lead.
Paris Green as a Dust Spray. One
pound Paris. green, thirty pounds of
air slaked lime or cheap flour. Mix
together thoroughly and dust on the
plants early in the morning while
the dew is on.
Poison Bait. One pound Paris
shorts moistened with one gallon of
water and sweetened with one or
two quarts of cheap molasses.
kerosene Emulsion. "a contact in
sectlc1de)., One quart kerosene, one
half pound hard soap, as Octagon,
one gallon soft water.
Make as follows: If water is
hard, add borax until it is soft
SHAVE the soap and dissolve in the
water Then add the quart of kero-
sene and churn back and forth into
itself for at least twenty minutes
OIL Will not separate and accumulate
on top. When thoroughly emulsified
add two and ,ene-half gallons Of
wat water to the above mixture, which
makes per cent kerosene emul-
all general garden uses.
Soap. Dissolve one pound Octagon
soap In from six to eight gallons of
water. Use for plant lice and soft
bodied sucking insects.
Tobacco. Boil one pound tobacco
stems or cheap tobacco in a gallon
a cheesecloth and dilute the material
with cold water until 1t is of the
same color as weak tea. It may be
used instead of soap.
bordeaux mixture. "a fungicide.
Three pounds copper sulphate, six
ter.
Dissolve three pounds of COPPER
sulphate in twenty-five gallons of
water. Shake the six pounds of stone
lime and make up to twenty-five gal
Ions with water. Pour the two solu-
lions simultaneously into a third
barrel through strainer. This
gives fifty gallons Bordeaux mixture.
AmnNniacal copper carbonate. Two
quarts, 20 degrees ammonia (strong-
est obtainable), six ounces copper
carbonate, six quarts water. Pour
the ammonia into the water. Be
careful not to inhale any of the
fumes, as this strong ammonia is
very powerful, and if handled in
close room may seriously injure the
worker. Stir in the six ounces cop
per carbonate. These two gallons
can then be put into bottle with a
rubber stopper. If desired, the whole
two gallons can be put in forty-eight
gallons water, making fifty gallons
of spray. For smaller quantities, put
one quart into six gallons of water.
This is a good fungicide and may
