Gus to go over the same grounds
again. but the numerous errors made
each year by orchardists of some ex.
perience, as well as noviccs, prompts
us to again call attention to a plan
of spraying for the coming season.
First. we should remember that
spraying is only one of the factors
in the production of good fruit. We
must feed the trees or adopt some
system of cultivation; prune inteli-
gently and regularly: thin the fruit
when the crop sets too heavily;
spray promptly and thoroughly; and
pick. pack and market with close at.
tention to details.
FIVE POINTS IN THE STAR or
SUCCESS.
Know the Trouble.
The very first essential in spraying
is to know our troubles and the best
combative measures. Many err at
this point and lose the labor and ex.
pense of applying the spray.
Spray Promptly.
The second cardinal point is
promptness A few days delay NAV
mean that it is too late for certain
spray.
Be Thorough.
Thoroughness is of prime impor-
tance If we raise a high per cent OF
perfect fruit, which should be the
ambition of every fruit grower.
Use Materials In Proper Proportions.
Spray solutions must be made
properly I'm the proportions recon.
mended or the results may be disap-
pointing and oftentimes disastrous.
Use a Good Outfit.
Lastly. good spray outfit will
make this as pleasant as any work
on the farm, but poor outfit will be
the bane Of our existence throughout
the spraying season.
Lime Sulphur For San Jose.
II we have the Sun Jose scale in
the orchard. it must be attacked Wig
orously every year to keep it in sub
lection. We can use the miscible
oils, lime sulphur. or whale oil soap
The lime sulphur solutions are used
more extensively than any other
treatment. This material can be
either prepared at home or pur-
chased ready for use. The latter is
10 be largely recommended, since our
equipment for boiling is usually poor
and the amount of time and labor
involved will scarcely balance the
convenience OF the commercial prod
uct
If we prepare the mixture our
selves, the following formula can De
used Fifteen lbs. flowers OF sulphur
and IS lbs. good stone lime to 80
gals. OF water. Boil the sulphur and
lime in u or 10 gallons OF water for
about an hour, dilute to 30 gallons,
and apply while hot on the same dav
1t is prepared.
If we purchase the material it will
require one gallon of the concen-
trated lime sulphur to nine gallons
OF water Apply while trees are dor
mant. II the infestation is bad, an
application late in the fall and an
The usual time TO apply this solu-
tion Is before the buds open in the
spring This will kill the San Jose
and other scales and destroy the
spores OF fungus diseases. Some or
chardists report good results in de-
stroying the eggs OF the apple
aphides or green lice.
The Summer Spray.
The second spray for apple should
be given just when the blossoms fall
mot while in full bloom) with either
bordeaux mixture or lime sulphur.
II Ben Davis, Gano, or Black Ben
are grown, much better results can
be secured by the use of lime sui
phur than by bordeaux mixture. A
number of other varieties are badly
russeted when sprayed with bordeaux
and the following season should give
summer spray.
The commercial solution should be
diluted, | gallon to 40 gallon of wa
ter including two or three pounds OF
arsenate OF lead to each so gallons OF
spray to control the codling moth,
curculio, and other leaf-eating insects.
II bordeaux mixture is used, a di-
lutte solution OF 2 pounds copper sui
phate (blue vitrioD and pounds OF
good stone lime. to so gallons OF wa
ter, including 3 pounds aTsenate OF
lead, should be effective.
The second spray should be given
two weeks after the blossoms fall
with the same solution used in the
previous one.
About nine weeks after the bios
SONS fall the next spray should be
given. 1t would be preferable at this
time TO use bordeaux mixture, espe-
cially In southern Ohio. II will not
cause much IL any russet at this time
and will be more effective than lime
sulphur in controlling bitter rot, ap-
pie blotch. and frog-eye fungus. The
solution at this time, for the second
brood of the codling moth, can be
mixed to include pounds copper
sulphate, pounds lime to 30 gallons
and 2 pounds arsenate OF lead.
