What To Spray With


mended for this use. but let "The
other Fellow try the New Things"
To supplement the spraying cam
paign for serious infestations it is
wise to band the trees with burlap.
covering a row diagonally through
the orchard each way. and by ex-
! amining and watching the bands
frequently, destroying any cocoons
found, a careful check on the de-
velopment can be made.
Thinning the Fruit
| The process of careful and eff
cient thinning of the fruit is one of
the most essential aids TO moth con-
troll.
All clusters should be broken and
reduced to one apple in a place. The
apples thinned to s to 10 inches space
and all apples removed especially
those containing worms or worm
stings destroyed, by feeding to hogs,
burning or soaking in barrels of
water over which there is a thin COW
ering of kerosene.
Give the thinners a bounty of 5
cents each for every "wormy apple"
they produce and these will be the
most valuable apples you ever grew.
Spraying Equipment.
The best equipment is none too
good. Every grower should own
the best high-powered spray machine
that he can secure. II should be
carefully cared for, pump and engine
kept in good condition, base strong
enough to carry 200 to 300 pounds
pressure, all couplings tight and the
ebst rods or guns, depending upon
the choice of the operator.
With large tall trees it is impossi-
BILE to correctly spray them without
having a tower on the spray outfit
from which the operators can reach
and apply the solution to the tops
of the trees. In serious worm in
festations it has been found that

upper u of the tree.
Time to Spray
The time of the first or CaIyx
spray be determined largely by the
conditions of the center blossoms of
the clusters. The center ones US
ually come out first and are the first
to close. The Calyx spray should
be applied, after the blossoms are all
out but not until after the majority
OF the petals have fallen from the
blossoms. Earlier applications are
fatak to the bees that are working in
the flowers. At this. time the calyx
Cup is open and if the receptacle is
filled with the poison solution, which
thorough spraying will do-you will
get the worm, before it gets the ap-
pie. The open period only lasts
about 10 to II days, hence the spray
ing must be done within that time if
the best results are secured. In Sc
riously infested orchards it may be
advisable to apply a double calyx
spray, the second application follow
ing the first in about a week.
Cover Spray.
Cover sprays are applied to cover
the fruit, and If its is kept properly
coated during the growing period,
worm free fruit can be harvested.
The number OF cover sprays will de-
pend upon thoroughness of opera
lions and weather conditions, which
largely influences the prevalence of
the moth. The longer the periods
of uninterrupted ranges of evening
temperatures of 60 degrees or above
the better the conditions for moth
This condition was
probably responsible in a large de-
gree for the unusual worm infesta-
ton in 1922.
First Cover Spray.
The first cover spray should be
applied about is to 81 days after the
calyx spray, usually this is about the
period of the eggs.
II weather conditions are favor
able for moth development or if the
orchard is seriously infested, a sec
ond cover spray should be applied in
about 10 to IL days.
At this season of the year the fruit
is growing rapidly and the coating
may become thin or broken so that
the small worms may gain an emit
rance into the fruit; hence due pre-
caution should be taken to keep the
fruit thoroughly coated.
II there are distinct intervals be-
tween the broods the third cover
spray should be applied about SO to
