3PRAYING APPLE TREES
WITH ARSENATE OF LEAD

WITH ARSENATE OF LEAD
Thurston White, former horticul-
tural inspector of this county, con-
Fibuted the following article to the
last number of the Denver Field and
Farm on the spraying of apple trees
With arsenate of lead that can not fail
to be of interest to local orchardists.
Il think the proper time to spray is
inst as soon as the bees quit work on
the bloom. Spray the second time
In one week and not later than ten
days. The third spraying should be
done from the 1st to the 18th Of July.
L consider three thorough sprayings
at the dates mentioned sufficient to
secure from so to 95 percent of ap-
Piles free from worms. At least 80
per cent of our growers are using ar
senate OF lead and l will give some
results of its use in plain figures:
Some time in October I think it was
Professor c. P. Gillette and 1 spent
1.-TWO days together making investiga-
tons around Canon City as to the
value of arsenate of lead.
~ The first orchard visited, the own
Gsof which did not believe in spray
Ing. was sprayed twice with Paris
nreen and we found 60 per cent OF
tie apples wormy. Just across a wire
feHce T. Watts sprayed three times
With arsenate Of lead and had only
ia per cent Of wormy apples. W.
IA Penney sprayed three times with
afsenate of lead and had only 81 per
totnt Of wormy apples. George Jack
son, used arsenate Of lead, sprayed
three times and had only 3 per cent Of
voTmy apples. James Turnbull used
arsenate with Az per cent Of wormy
apples. This orchard had never been
thoroughly sprayed before George
Broughton used arsenate of lead and
had only two-thirds' of one percent of
w0rmy apples. J. R. Broughton spray
ed three times with arsenate Of lead
and his percentage was about the
same
Frank Linquist used arsenate Of
lead and sprayed part of his orchard
two times and the other three times.
The per cent of wormy apples in that
part sprayed two times was s, while
only 8 Is per cent was found in that
part sprayed fGs1 efmes. He used
paris green the year previous and es-
ltimated that fully so per cent of his
apples were wormy. The best results
were found later by myself in the Or
chard Of G. H. salie. He sprayed three
times using 2h pounds Of arsenate OF
lead to nifty gallons OF water. I made
count of 400 Ben Davis apples-200
from different trees and 200 from the
pile OF apples he had gathered with
out finding a single wormy apple.
b. this time l became more inquis-
tive, and began to look in earnest for
wormy apples. After carefully exam
lining great many trees l failed to
find a single wormy Ben Davis apple.
Furthermore | do not believe he had
two bushels of wormy apples on four
that good results can and are attained
with paris green or arsenate of lime,
but l prefer arsenate of lead to any
other for two reasons: There is no
danger OF burning the fruit or foliage.
In the second place 1t adheres to fruit
better. showing plainly for several
weeks after heavy rains. Get good
spray pump that has plenty of force
SO that 1t will drive a medium fine
spray right into the calyx of the ap-
pie Next get a man and a good one
behind the nozzle-that is, hold Of
the handle, one that is not afraid of
hard work Spray from the four an
giles of the tree and hit every blossom,
using as much as fifty gallons OF spray
to every seven or eight trees twelve
to fifteen years old.
