'ther hot bed, cold frame and green

ure should be applied at intervals
Il 10 days to two weeks. 1t should
,e remembered that proper ventila-
SON Of the beds or house in connec-
tolN with the spray is important.
Where one wishes to control these
diseases the soil should be allowed
% become quite dry until they are
checked, through the use Of the spray
md the ventilating. Then by the
lse OF the spray at regular intervals
me may again come back to the
Usual practice In watering.
Ammoniacal Copper Carbonate Solu.
- "... ton.
This preparation Is used where
we does not wish to stain the fol.
age. It Is made by using six ounces
! II copper carbonate, strong am.
nonia GO degree Deaume) about
hree pints, soap one pound, water
70 gallons. To make up this mix.
! Mre place the copper carbonate In
! tone vessel, pour on just enough
ammonia to make 1t into paste.
Add more Of the ammonia and stir 1t
Up thoroughly. Allow 1t to settle
md pour off the clear ammonia
| liquid. Then add more ammonia,
Itir thoroughly again, and again
! your off the clear liquid. Repeat
his until all the carbonate is dis
lolved being careful not to use more
ammonia than Is necessary to dis
Iolve the copper. When the mater
al has been dissolved, water may be
.dded to make 40 gallons. Dissolve
he soap in 10 gallons of water and
Jour into the carbonate solution.
To make up stock solutions OF
his preparation, 1t Is suggested
hat the copper carbonate solution
.fter being dissolved in the ammonia
AVE only water enough added to
make six pints. 1t may then be
'laced In stone jug and corked up.
n this manner it may be kept in
definitely. The soap could be dis
olved in six pints of water. This
'ould also be placed In a stoppered
,ottle or jug. To make up small
mount of the spray from these two
took solutions. one could use one
lint of the carbonate solution which
would contain one ounce OF the car
,onate, and dilute with about 2-3
,allons of water Take one pint OF
he soap solution and dilute with
!-3 gallons Of water. Pour the two
lilute solutions together and mix
hem thoroughly and the spray Is
eady for use. This is used in the
anne way that one would use Bor-
leaux.
Lime-sulphur Solution.
Lime-sulphur solution is used to
.ontrol plant diseases and sucking
Insects as we'll. This spray mixture
9 not desirable generally in vege-
able growing work, because Of the
tanning of the foliage and the
lwarflng Of the plants In some cases.
one Is planning to use only small
mount Of 1t, 1t may probably be
most cheaply made by buying the
concentrate solutions of drug or
.hemical companies. 1t is made by
most Of the large chemical companies
md by paint manufacturers. The
concentrated solution should be di-
uted according to the formula given |
IN the package. This is usually |
lbout one part Of the solution to 25 |
n 80 parts Of water. If 1t Is used in |
vegetable growing, it should be I'M
iertaken with caution.
For mildew in the hot beds and |
green houses, potassium sulphide is |
,ften used. This is comm nly known |
Is liver of sulphur. This Is made ur |
~ adding one ounce Of the snlphida
% two gallons Of water. The sui
,hide should be kept in tightly |
,toppered bottle.
Spray Mixtures for controlling rlAn'
Diseases. !
The following are the formula
for the leading spray mixtures used
to combat plant diseases.
Bordeaux Mixture.
This Is a standard fungicide 70,
vegetable crop spraying. 1t is made
from copper sulphate, fresh stone !
lime, and water. Use four pounds !
of copper sulphate, four pounds O: |
lime, and SO gallons of water. Dis
solve the copper sulphate and dilute
to 25 gallons Of water. Stake the
lime in small amount Of water and
dilute to rs gallons Pour the two |
solutions together from height Il !
possible 50 as to mix thoroughly !
The mixture should be passed /
through a strainer In filling the spray !
tank in order that the sprayer may !
not become clogged by any small
particles Of lime A slight excess Of
lime in the mixture will do no harm ,
and will be good insurance against
having too much copper sulphate |
which Is harmful.
Where one is to use this mixture
all summer long. 1t is a good plan |
to make stock solutions OF the sui |
phate and Of the lime. This Is done
bv dissolving a number of pounds Of
copper sulphate in the same number
of gallons Of water This places 9
gallon Of sulphate in each gallon OF
the solution. The lime may be
slaked and also placed into as many
gallons Of water as there are pounds
Of lime. To make ND some Of the
mixture. stir the separate solutions ,
thoroughly and dip out as manv gal.
Ions as one wishes pounds. Dilute
each solution snff'ci entlv. then pou,
together TO make the finished pro,
duct. The concentrated solutions
should never be poured together be.
cause thew will fail to stay in sus.
pension when the Bordeaux il made
in that way. A good way to dissolve
the copper sulphate is to suspend the
required amount in a gunnv sack or
cloth bag in the top Of the water in
