at the Matching period, or il
other words, get the poison OF
the trees just the day before
they hatch as this Matching per
iod covers the time from about
the first of June until the first
of October, thorough, efficient
frequent spraying is the only
control method.
WHAT TO SPRAY WITH
l suggest spraying with arsen-
ate of leads pounds of dry to
200 gallon tank for the calyx
spray to catch the leaf roller,
and A pounds for the cover
spray-because it is the recOg.
nized standard material used for
that purpose. Some growers use
a larger amount, but if this
strength lis thoroughly applied
control is usually secured. Each
year there are other products
recommended for this use, but
let "THE OTHER FELLOW
TRY THE NEW THINGS"
To supplement the spraying
campaign for serious infesta-
ton it is wise to band the trees
with burlap, covering a row d.
agonally through the orchard
each way, and by examining and
watching the bands frequently,
destroying any cocoons found, a
careful check on the development
can be made.
THINNING THE FRUIT
The process of careful and
efficient thinning of the fruit is
one of the most essential aids
to moth control.
All clusters should be broken
and reduced to one apple in a
place. The apples thinned to 8 |
to 10 inches space and all apples
removed, especially those con-
tanning worms or worm stings |
destroyed by feeding to hogs, |
burning or soaking in barrels of |
water over which there is a thin
covering of kerosene.
Give the thinners a bounty of
cents each for every "wormy |
apple" they produce and these
will be the most valuable apples
7ou ever grew.
SPRAYING EQUIPMENT
The best equipment is none
90 good. Every grower should
wn the best high-powered spray

Jump and engine kept in good
onditions, hose strong enough
carry 200 to 300 pounds I

With large tall trees it is i'm

TIME TO SPRAY
The time of the first or Calyx v
Yray should be determined larg t,
7 by the conditions of the center b
ossOms of the clusters. The d
inter- ones usually come out E
st and are the first to close. 81
lie Calyx spray should be ap il
led, after the blossoms are all W
t but not until after the maj ii
lty of the petals have fallen al
,m the blossoms. Earlier ap- ii
cations. are fatal to the bees a.
at are working in the flowers.
this time the calyx cup is

with the poison solution,
itch thorough spraying will do
u will get the worm before
gets the apple. The open per-
only lasts about 10 to IL 4
VS., hence the spraying must
done within that time if the
IT results are secured. In SER ~
