RECIN PEST WAR
NOW SAYS HILL
II is Time to Think About
and to Begin Pest Con-
troll Work Now

Realizing this, Edward w. Hill,
a;str;ct horticultural inspector writes
tb;s letter to the grower urging him
g nrotect his fruit by starting the
war on pests early and keeping after
them.
at is time that we were thinking
about the planning for the 1925 fruit
crop. Your pruning should begin ear
,v MANY are of the opinion that prun-
ing early will be injurious to the tree.
This idea is false and as rule results
in throwing all of the spring work to-
pether, and usually results in late
spraying through the season. The
trees should be thinned out enough
(not headed back) to permit easy
and thoro spraying and to permit
plenty of sunlight through the tree.
an regard to the scale, past ex-
perience has proven that it is not a
difficult insect to control if proper at
tention is given to spraying and the
cleaning up of infested brush and
trees. Now is good time to cut the
willows and cotton wood trees sur
rounding the orchard. Don't wait
until 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 effec-
tive work may be done. 1t is grow
ers civic duty to report any neglected
orchard. It will cost too much money
to put man in the field to ascertain

must be fifteen or twenty days after
