DuRDlE ON TIMELY TOPICS

During the past week number
OF trees have been top worked tor
growers in several communities OF
the county for the purpose of i'm
proving the pollination of solid blocks
of apples and pears which lack polli-
nizing varieties. At the T. A. Spratlen
tract at White Bluffs, 10 Winesaps
were grated to Rome Beauties. At the
David Zerwekh pear tract. between
Hanford and White Bluffs,
d'Anjous were top worked to Bart
let's. At the L., A. Codding and
Heideman tracts north Of White
Bluffs, and the Hawthorne tract
north of White Bluffs, Jonathans and
Winter Bananas rs were put in as
pollinizers for Winesaps. At the A.
E. Starkenburg tract east of Prosser,
40 trees are being worked over to
Red Delicious with an occasional tree
grated to Jonathans as pollinizers
for the Red Delicious. This tract
is ten acre tract in which yield has
been running down since the Romes
and Jonathans which were near the
orchard have been removed.

Whether the moth trap can be used
as a direct control measure for the
cooling moth may be a debateable
question, but. there is no question
whatever as to its use as an aid in
determining spray dates. Many farm
ers throughout the county have used
the moth trap for one or two seasons
and have found that it is an excellent
means of determining just when the
spray should be put on. through the
aid OF the moth trap, one could deter
mine just when the moths are begin
ming to fly and then figuring ahead
10 days be sure that sprays are
applied to-. cover this time. Traps
should be placed out over the orchard
and dependence placed upon the moths
caught in these traps rather than
moths caught in traps Immediately
about packing sheds or near brush
piles. Moths emerge from about pack
ing sheds earlier than out in the
open orchards. l~frs;g
Tor few traps, ordinary five
pound lard pals dipped or painted
with aspha1turn paint serve the pur-
pose very well. Where larger number
are used, a granite kettle or pan of
suitable size, depth and diameter can
probably be purchased to good ad-
vantage if purchased in any quantity.
A local dealer at Kennewick was
able to furnish small granite pans
last year at a cost of about 13c to
the grower.
The bait used may be apple cidar,
one gallon; brown sugar, 10 pound;
and one cake of yeast which is diluted
with four gallons of water after fer
mentation begins. Diamalt put out by
the Fleischman's Yeast Co. may be
used according to directions furnished
by the Company. A good grade of
molasses such as the Brer Rabbit or
any other such grade may be used
by diluting and using yeast in it to
start fermentation.
Traps will give much better results
il supported on pole with side arm
placed near the top of the tree. Traps
s.lculd be high and should be on
something rigid to prevent their be-
ing swayed too much by the wind.
A couple Of screw eyes and tied
twisted cotton cord can then be used
to raise and lower the trap. 1t is
very important that the traps be kept
cleaned out and that supply Of
liquid be kept in the trap at all times
during the period of moth flight.
! The County Agents office at Ken
newick has number of copies Of
bulletin No. 214 on the codling moth
trap which we would be glad tc
furnish any grower wishing more
information.
