the breeze the dust is blown away
from them, busting only on one side,
and in case Of large trees waiting
until the breeze has changed to dust
the other side. By so doing little or
no discomfort is experienced from
the dust. If the dust is blown back
on the operator it will cause his eyes
to smart and for this reason it seems
best to wear goggles.
Weight or Outfit
THE dust rig being considerably
lighter than the spray rig. chiefly be-
cause Of the absence of water, it is
often impossible to get buster on
ground in which sprayer would be
mired. Being lighter in weight. it is
much more easily handled through
orchards situated ON hilly ground.
Another advantage is in case of
scarcity of water, none being re-
quired in the use of the duster.
Reasons for Not Spraying
Numerous reasons have been given
by owners Of orchards for not spray
ing, some Of which are: Too much
trouble; too expensive; too busy;
hard. dirty work.
THE latter may be true, especially
IL the work is not done with the
proper equipment. Too busy and too
much trouble seems to be the most
valid reasons why they should not
spray. The busting method will
therefore appeal very strongly to
such people, for the work can be done
very quickly and with very little
trouble and without interfering to
any great extent with other farm
work. The busting method has been
under trial for nine years in various
New York orchards, and comparing
one year with another, the results
thus far have shown that the dust
controls the codling moth even better
than the liquid spray. Up to the
year 1920, no dust had been put on
the market to take the place of the
dormant spray, but experiments are
now being conducted with view to
remedying this deficiency.

using all raw material. The machine
should be in good working order, so
as to be able to shut off the dust in
stantly. In orchards where there are
solid blocks of 20 to 30-year-old trees,
the shut off is not required, for as
soon as one tree is passed, the funnel
should be directed to the next; the
horse continues walking, stopping
only for the hopper to be filled after
busting about 100 trees.
Nhe apple scab. however is not con-
trolled quite as well by dust as. by
liquid. This is accounted for by the
fact that the PARTICLES of sulphur are
! not so fine in the dust as in the liquid,
therefore do not stick on as well.
Application
Tho dust mixture is applied with
an OUTFIT which depends on a rotary
fan to furnish an air current, and
which is provided with hopper and
feeding device with which to drop the
mixture slowly into a tube from which
it is blown onto the trees The dust
may lie applied so rapidly that it is not
necessary to stop the horse as you
! SOAfiS ~ titC tlCc, tHcTclOT6, the time
consumed in busting an acre depends
on how fast the horse travels. BY a
little movement of the dust regulator
one can put on the required amount.
The secret of obtaining apples free
from disease and insect injury lies in
the timeliness of the application of the
proper materials. The materials
should be applied four or five times
I during the season. as experiment after
experiment has shown. These times
are: The dormant: the pink bud: the
| calyx; in about three weeks the fruit
and foliage. and then again four weeks
later. While the last two applica-
tions are necessary for the control of
at the same time protecting the fruit

moth.
prof. Whetzel of New York tells

| ments the average of scah on I'M
sprayed trees was 43 per cent. on
sprayed trees II per cent. and on
busted trees ~ per cent, a difference
OF only l per cent. between the dust
ing, and spraying methods. On the

cent. worms as against, per cent.
| busted, while on unsprayed trees there
| was Fl per cent. In other words, the
| dust gave better results than the spray.
| Three years experiments in Nova SEQ
| tia gives an average of so per cent.
scAb on unsprayed trees. which is re-
| duced TO 10 per cent. on unsprayed
and per cent. on busted
Wishing to demonstrate the effec-
| tiveness of the busting method in or
chards for disease and insect control,
last spring 1 obtained buster and
1.-TWO tons of dust with which to DEM
| onstrate and with the assistance of my
inspectors busted orchards in Gardi-
ner, Augusta. Winthrop. Monmouth,
Greene. Auburn. Mechanic Falls, Po-
land, New Gloucester. Standish, Seba-
go, Jefferson and Union. Several or
chards were busted for the pink bud,
calyx and fruit and foliage spray. This
was after the orchards had received
the dormant spray. The work was
thoroughly done and gave universally
good results.
las time saver there is no COM
parison between the liquid and the
dust. In one orchard we busted 500
trees in 81 minutes. covering six acres
and using 800 pounds Of dust. In an.
other orchard we busted lis trees in %
minutes with 100 pounds of dust.
These trees covered four acres. An
