Sprays for Fungicides.
The control of fungous diseases is
accomplished by the use of some
form of copper salts, usually copper
sulphate or copper carbonate.
The former known as bluestone
blue vitriol, ETC., is generally recog
nized as more efficient than the latter
When purchased in large quantities it
is also cheaper.
Copper sulphate may be used on dor
mant plants when dissolved in water
at the rate of two pounds to so gallons
of water. but this solution must not be
used on growing plants.
Copper sulphate in combination with
fresh lime forms the standard and

Bordeaux Mixture.
Various formulas are quoted, but the
following is accepted as safe and re-
liable:
Copper sulphate ....... 5 Lbs.
Fresh lime .............. Lbs.
Water ..................5 so Gals.
In general terms, the copper sui
phate should be dissolved in one-half
of the water, the lime slaked in the
remainder, and the two solutions
poured together. This results in a
chemical action giving roe to a new
substance preserving the fungicidal
properties of the copper sulphate, and

Making Bordeaux Mixture.
Have on hand three barrels and two
pals wood or fber).
twenty-five gallons of water in each
of two of the barrels.
Dissolve five pounds of copper sui
phate in one barrel by suspending in
a coarse burlap as near the surface OF
the water as possible; in this way il
will dissolve in a few minutes, while
if allowed to settle to the bottom ii
would require several hours or even
days to dissolve.
Place the lime in pail and slake by
adding water slowly until paste is
formed THE lime for bordeaux mix
ture should be slaked exactly as fol
building purposes.)
Pour this lime paste into the sec
ond barrel and stir thoroughly.
Now pour into the third (empty)
barrel first a pailful of the copper
sulphate solution, then a pailful of lime
water, or better, let two persons worl
at the job, pouring together.
The resultant mixture should be o
an intense blue color. If any tinge O
green appears it is not good bordeaux
