Piaut III the 10TH OF very nne spray
will do more good than much greater
amount imperfectly applied. A gallon
or gallon and half should spray
tree of average size. The disease must
first be determined and the treatment
| fitted to the disease. The indiscriminate
use of fungicidcs may do more harm
than good.
Experience shows that bordeaux
mixture or ammonical carbonate of
copper solution may be. properly used
for numerous diseases. An objection to
bordeaux mixture, especially on fruits,
is that it leaves quite a deposit of solid
material. This may, however, be easily
washed off from the fruit with soIu-
ton of vinegar. quarts to 10 gallons of
water. All fungicides should be kept
in wooden. glass, or earthenware, never
in iron vessels. Formulas for more
common fungicides with brief directions
for their preparations and use are given
below:
l. Simple Solution of Copper Sulphate:
Copper sulphate (blue vitriol or blue
stone) pound, water soft 90 gallons.
Dissolve the copper in the water. This
solution will keep indefinitely. 1t will
cost about one-fourth of a cent per
gallon. Paris green or London purple
2 ounces to 90 gallons) may be added
and the mixture may be used as com
bined insecticide and fungicide.
2. Simple Iron Sulphate Solution: Iron
sulphate (copperas) 5 pounds, soft water
% gallons. Dissolve the copperas and
use at once. 1t costs about one-half cent
per gallon. Insecticides may be COM
bined with this fungicide.
3. Bordeaux Mixture: Copper sulphate
(blue vitroD, pounds; unslaked lime,
pounds; water, % gallons. Dissolve
the copper in 16 gallons of water and
slack the lime in the other 6. Stir the
lime well and strain the thin whitewash
into copper solution, stirring it well.
Always observe this order of prepara-
ton, as it is said to spoil the mixture if
the copper be poured into the lime.
Keep we'll stirred and use at once. The
tendency this mixture has to fill up the
nozzle of the sprayer is its greatest
drawback. Paris green or London pur-
pie e ounces to 20 gallons) may be com-
bined with this fungicide. 1t costs about
1-3 cents per gallon. In another for
mula instead of 6 pounds of copper
sulphate is used with about as good re-.
suits.
4. Eau Celeste: Copper sulphate. /
pound; ammonia (220) l 1-2 pints; water,
% gallons. Dissolve the copper in 2
gallons of hot water. When cool, add
the ammonia and reduce to 90 gallons.
This costs about l cent per gallon. In
secticides cannot be used with this.
Z. Ammonical Copper Carbonate
Compound: Copper carbonate, q
ounces; ammonia carbonate, / pound;
water 90 gallons. Dissolve copper and
ammonia carbonate in half gallon of
hot water. Dilute to so gallons and use
at once. Insecticides cannot be used
with this. Cost of this mixture about
1-2 cent per gallon.
Another formula for this solution is
as follows: Copper carbonate, 3 ounces;
ammonia (220), quart; water, % gal.
Ions. Dissolve copper in the water, add
ammonia and use at once.
A third formula is copper carbonate.
ounce ammonia, carbonate 6 ounces.
Powder and mix thoroughly. This may
be kept in dry state in alright vessels
for any length of time. When needed
for use dissolve in 10 gallons of water
and use at once.
A fourth formula which is said to be
equal to any of the others and a little
cheaper, but which has not been tested
as much as the others is copper sui
plate one-half pound, ammonia car.
Donate pound, water SO gallons. The
ammonia Carbonate should be hard and
transparent, otherwise 1 and a quarter
pounds will be needed. Dissolve it in a
pail of hot water. When foaming ceases
add copper and stir as long as there is
any foaming. Dilute to 62 gallons and
use at once.
These four formulas are practically
the same. or nearly so, and the solution
formed is one of the most valuable with
which to combat plant diseases. With
out the Objectionable feature of the Dor
deaux mixture it probably ranks next to
that inefficiency. However, insecticides
cannot be used with any of these as they
can with the bordeaux mixture.
In none of the solutions containing
ammonia or carbonates in any form
should Paris green or London purple
ever be used, unless quantity of lime
is added as the chemical compounds
then formed are injurious to foliage.
