COOLING MOTH CONTROL

Codling moth control by spraying
las been somewhat complicated by
the difficulty encountered in England
last winter owing to the presence OF
Cn alleged damaging spray upon
apples. In order to cope with this
slluat,on spray program has been
constructed by q. T. Clawson, F. II.
Ayres, Leo c. Antics, Charles Rob-
inson, Roy Larsen and Lynn L.
Allyn of the American Fruit grow
ers, Inc, for the benefit of all Skoo-
KUN and Blue Goose growers, ac-
cording to bulletin issued by Myron
S. Foster, president of the Northwes-
tern Fruit Exchange.
Following is the program:
1st. The use of Thermometers to
determine the proper time ior the
application of the first cover sp.ay
as explained by E. J. Newcomer Oh
the United States Department OF Ag-
riculture.
End. That each and every twig and
leaf on every tree be thoroughly wet
with spray.
3rd. That two pounds of dry Arse
nate Of Lead per one hundred gallons
be used in the Calyx Spray.
4th. That four pounds OF dry Ar
senate of Lead per one hundred
gallons be used in the first and second
cover sprays, and that two pounds dry
Arsenate Of Lead per one numbered
gallons be used on all succeeding
cover SPRAYS.
5th. That each apple be kept
thoroughly cove-ed at all times from
the date OF the first cover spray Till
July A. ).
thoroughly that no later sprays be
needed.

also issued bulletin on ea.iy irriga-
! ton as prepared by Leo. c. Antics
O. T. Clawson, Ray Larsen ana
Charles Robinson as follows:
EARLY IRRIGATION
Several years of personal abserva-
tions in various districts and Our owl
experiences. convlnces us that
thorough irrigation prio' to blossom
( ing time tends to strengthen the bios
som buds and increase the per cent ol
/ the fruit set, lessen the June drop ano
increase the wood growth, size OF lea1
and general vigor of the tree.
/ Freezing is drying process. Ar
abundance of moisture in the soil anc
the pant reduces this drying eftec,
at any given temperature. In many
cases a thorough irrigation prior II
blossonaing time has assured trul,
olop in face of frosts which cleaned
out adjoining ttacts. The use Of water
or heaters are the two methods ol
frost control. In the Wenatchee, Okan.
ogan districts the occasions have beer
rare indeed when abundant moistu
would not have assured ample pro-
lection from frost.
early irrigation dissolves the nit
rogen in the soil and makes it avail
able fon the use of the tree at time
when the buds are most needing stirn'
ulat.on.
TREES NEED WATER
apple trees in their normal habitat
are standing il mud at this time Of
year. Here we have protractee
drought each sping from the time t1s
snow melts until irrigation starts.
This year there has been very LITTLE
snow and the soil has had more thar
normal length Of time to dry out
Soil tests made in vaious places in
dicate more than normal lack of mos
ture. The spring is carly and fros
danger is imminent.
I'VE believe it highly importan
that each orchard be thoroughly irri
gated prior to blossoning time thi
spring.
We are now irrigating our own or
chards and the orchard managers o
the American Fruit Growers, Inc
have each been instructed to have thei
properties thoroughly irrigated BY
