Lame Sulphur solution.


a good fungicide. A few years ago
our present lime-sulphur solution
was developed for the purpose of
spraying certain plants that have foli-
age too tender to be successfully
sprayed with Bordeaux Mixture. This
solution has proved so successful in
combating both insects and plant dis
eases that IL is now one OF our stand
ard spray solutions. 1t Is especially
valued as winter spray for killing
scale insects and dormant stages of
fungi that remain over winter on .he
branches and trunks OF trees and as
q summer spray for spraying apples
for scab. roses for mildew, and
peaches and plums for brown rot and
scab.
Idme-sulphur has come into such
general use that IL Is now made and
sold by all of the leading spray
manufacturers I'm the country and Is
handled by druggists everywhere. The
commercial lime-suiphur solution is
n clear. amber colored liquid. contain
ing calcium sulphide i'm solution. 1t
In made from heating lime and sui
phur together. Calcium sulphide Is
the active agent that kills the fungi.
This solution is very caustic ana IL
used I'm too great concentration win
kill the plants. Practically all of the
commercial solutions OF lime-sulphur
on the market are guaranteed to have
n density OF SO degrees Beaume, and
dilutions are recommended on this
basis. When 1-9 Is recommended for
spraying plants that are dormant, we
mean gallon of lime-sulphur with
a density~of 32 degrees Beaumc TO s
gallons OF water. IL IL essential that
the density be known because OF
course the greater the density the
stronger" II Is.
Commercial lime-sulphur 10 used
almost entirely now for winter spray
and Is being used quite largely for
summer spray. 1t is perfectly safe
TO use IL on apples and roses and 9TH
er plants with foliage not especially
sensitive. In such case. use one gal
Ion OF commercial me-sulphur to 35
gallons Of water. With peaches and
plums and some few other plants
that have especially sensitive foliage
commercial lime-sulphur Is not al
ways safe. Under certain conditions
IL seems to injure the foliage. For
peaches and plums. use I gallon OF
commercial lime-sulphur to so gal
Ions OF water. For apples and roses
use I gallon of commercial lime-sul-
phur To 80 gallons OF water. II seems
better and safer. however, to use the
self boiled lime-sulphur for these
tender foliage plants for the present.
IL is just as efficient and never in
jures the foliage.
In making self-boiled lime sui phur
use pounds OF fresh quick lime and
pounds OF sulphur (lour) to so
gallons OF water. Make this up by
placing the eight pounds OF fresa
line I'm n tub or barrel and add Just
enough water TO slake II. An excess
of water seems to drown the line and
rec'rds the shaking process. AS soon
as the lime begins to crumble apart
and violent boiling Is set up, adj
eight pounds of sulphur and stir In
thoroughly. adding enough water TO
keep any part OF the mixture from
becoming dry o. burning. Keep this
wolf stirred and allow the boiling 20
continue for from to 10 minutes.
Special care should be exercised AT
this time TO keep any part OF the mix .
turo from becoming dry. Enough
water should he added i'm fact so that
the paste is thin enough to he easily
stirred. After the boiling mas con-
tinued for or 10 minutes, enough
water should be added to cool the
mixture. IL IN then ready TO apply
a pump with n good agitator should
he used so as to keep any part OF the
mixture from settling out. Lime sui
phur solution should be applied with
force OF about 100 pounds pressure "a
the square inch.
