Spraying Frui. Trees.

70 the importance Ot spraying, Dut among
some there is lack Of knowledge as to
tue best remedies and methods OF apply
ing them, accordingly will give few Of
the points that were brought out at the
meeting last Saturday and some that
were not discussed but that arc OF special
interest to our younger fruit growers.
The Goblin moth 10 our most common
enemy and the one that requires atten-
ton in every orchard 10 the valley where
the apple, pear and ounce trees have
reached the bearing age. The eggs Of
the moth are deposited about the time
the bloom falls from the trees and in
about ten days they begin to hatch ont
and the young worms feed around in the
calyx of the little apple or pear day or
so before they begin to burrow toward
the core. It 10 while feeding about in
the calyx that taste Of the arsenites
that have been used in spraying is taken
with fatal results to the worms- The
proper tino TO spray will therefore be
after the blossoms have fallen and before
the calyx will have closed up, which it
does gradually as the fruit develops, and
then second spraying in about ten days
should be given to insure the feast Of

should occur to wash out the poison, It
will be advisable to give third applica-
ton.
The most common spray for the Goblin
moth is mixture of Paris green, in the
proportion OF I pound to 2OO gallons OF
water, to which about pounds Of quick
lime should be added to prevent tho
caustic properties Of the poison from in
juring the foliage. For the second and
third applications the mixture should be
made less strong, using about 3O0 gallons
Of water. London purple ls used in the
same way but is thought by some to be
more liable to injure the foliage than the
Paris green.
There is much difficulty experienced
by fruit growers In getting the pure ar
ticle in these poisons and to meet this
emergency the remedy which was recent

credit for thnt mixture should be given
TO Prof. r. @. Kedzie Of the Michigan
Agricultural College, as it has only been
introduced into our state aud recon-
mended to our people by Judge Osborn
Of Loveland. The following are the di-
rections for making it: Boil 2 pounds Of
white arsenic aud = pounds OF salsoda for
fifteen minutes in two gallons IT water.
Put into jug, label poison and lock it
mp. When ready to spray slake pounds
OF lime and stir it into 40 gallons OF water
adding a pint OF the mixture from the
jug. II will be observed that the direc-
tions as printed above give 8 pounds Of
the salsoda instead Of 4, as in the direc-
tions published heretofore in this paper
and others, and this correction should be
especially observed as It is an important

The blight is q bacterial disease of the
apple and pear for which there is NO
known remedy except to cut away the
affected parts rs fast as indications of the
disease can be noticed. This treatment
will tend to check the spread Of the dis.
ease and il persevered in will finally over
come it entirely, but to do this requires
the utmost caution on the part Of all
fruit growers, and whenever limb or a
twig is cut of it must be burned or else
the germs may spread as rapidly from
the affected parts as readily us il still on
the tree. The most important time to
keep close watch Of the blight, and the
time when 1t spreads most rapidly, is
spring: At that time the sap will fre-
qnently ooze ont Of the bark Of the trees
affected with the blight, and as there is
little else for the bees to work on at that
time they will carry this diseased sap to
the blossoms of healthy trees and the dis
ease is spread over. vast scope of terri
tory ina short time. Keep the orchard
in as near a normal condition as possible
at all times, allowing it to get neither too
dry 30 us to stunt the tree in it's growth,
nor cause it to grow too rapidly by over
supply of moisture, as either condition
lays the tree liable to the attacks Of
blight.
Keep a sharp look out for the rust of
the black raspberry, which is a fungus
disease, and one that is very hard to get
patch. In the advanced stage of this
disease the best remedy is to dig out the
bush entirely, but 1t can be held in check
and even eradicated il taken in time by
spraying with the dilute Bordeaux mix
ture, which is the greatest spray yet dis
covered for all kinds of fungus diseases,
rots, molds, mildews. etc. The following
are the directions for making it for use in
all ordinary cases: Copper sulphate,
(blue vitroD 6 pounds; quick lime, 4
pounds; water 40 gallons. Dissolve the
copper sulphate by putting in a bag Of
coarse cloth and hanging in vessel con-
tanning at least gallons of water 30 that
it is Just covered. Use an earthen or
wooden vessel. Slake the lime in an
equal amount of water. Then mix the
two and add enough water to make 40
gallons. It is then ready for use but will
keep indefinitely.
For all soft bodied insects that do not
have biting mouths, but suck the sap
from tree or plant through beak, the
kerosene emulsion is most effective and
does its work by coming in contact with
and soaking through the skin OF the in
sects The woody aphis belongs to this
type and to make the treatment effective
the emulsion must be applied as early in
the season as the aphis are found to be
above ground, as they will get such
thick covering of the woody substance
over them later in the season that it is
next to impo ssible to penetrate the COW
ering and get the spray onto the body OF
the insect.
The developement that is now in
progress throughout the Rocky Ford
country is well illustrated by changes
which have taken place on the J. N.
