1T is TIME TO THINK ABOUT
AND BEGIN PEST CONTROL
WORK

1t is time that we were thinking
about and planning for the 1925 fruit
crop. Your pruning should begin ear
iy. Many are of the opinion that prun-
ing early will injure the trees. This
idea is false and as rule results in
throwing all of the spring work to-
gether, and usually results in late
spraying through the season. The
trees should be thinned out enough
(not headed back) to permit easy
and thorough spraying and to permit
plenty of sunlight through the trees.
SCALE CLEANUP
In regard to the scale. past expert
ence has proven that it is not diff
cult insect to control if proper at
tention is given to spraying and the
cleaning up of infested brush and
trees. Now is a good time to cut the
willows and cotton wood trees sur
rounding the orchard. Don't wait I'M
til spring work makes it necessary
to put off cutting down these trees
until some other time.
The Horticultural Office is anxious
to do everything possible to help in
this cleanup work, and it is hoped
that with the closer cooperation Of
everyone concerned that more effect
i've work may be done. 1t is grow
ers civic duty to report any neglect
ed orchard. 1t will cost too much
money to put man in the field to
to ascertain the orchards which are
infested with scale Gan infested or
chard has to be inspected, and we
are compelled to find the live scale
, before the property can be condemn
ed). All property owners must be
given a certain length of time to
clean up, which as rule must be
fifteen or twenty days after the water
is in the canal. Now growers, if
there are any soaley trees near you
which need to be cleaned up, please
notify US in time to get the work
done this spring. might say at this
time that there is no danger of the
spread of scale until the LIST of June.
GOBLIN MOTH CONTROL
Another part of the cleanup cam
paign on orchard pests which might
be proftably started at this time is
the scraping of the trees to remove
the old rough bark, which forms an
ideal wintering place for Goblin moth
larvae. I wish to cite you few fig
urcs which might be interesting. One
female moth will lay about 30 eggs.
We have two broods and big por-
ton of third brood. One moth will
give you 80 worms the LIST brood.
Divide the 80 by 2, to take care of
the males and worms that die nat
urally, which will give you IS female
worms that will produce 80 worms
each for the second brood, or $50
worms. Run this down to the 3rd
brood, and it will amount to $3.50
! worms during the season for each fe-
male worm that gets by you in the
spring Mr. ]. D. Sutton of Prosser
has scraped his trees, and has killed
on the average of twenty-five worms
to the tree. Take half of the twenty
five for the female worms and multi
ply $50 and $3.50 by it, and we get
5.625 second brood worms, or e3,375
third brood worms per tree, Or $685.
$50 second brood worms or 6,536,250
third brood worms per acre, that Mr..
Sutton has rid himself of. Will it
ray2 Yes, 100 times. 1t is the most
effective method of control against
the stings. Referring to the above
figures, it is fair to assume that
wormiEg your trees will raise your
&c" Grades and culls to higher grades
by so per cent.
