should be planned so as to make sure that
the first application of arsenate of lead is
completed by the time the peaches have
forced themselves through the shucks. If the
acreage small, this first application may
be delayed somewhat, until the shucks start
to shed, provided the spraying can be COM
pleted by the time the shucks have shed.
Second Application
Two to three weeks after first application:
One pound powdered arsenatc of lead in self
boiled me-sulphur, $3.50.
Third Application
One month before ripening: One pound
, powdered arsenate of lead in self-bOiled lime
sulphur, $500
Fourth Application (optional)
Ten days to two weeks before harvest, II
brown rot is appearing and rains are fire.

Peach foliage and fruit may show injury
from three applications of arsenate of lead.
Injury will be more pronounced on the older
trees, especially those on thin soil, and
making comparatively little annual growth.
Vigorous trees on strong soil are least likely
to suffer. Growers must decide whether, i'll
view of curculio abundance, the three
arsenate Of lead treatments should be given.
If, after the second spraying, much injury
shows up, the third application might be
omitted, or the amount of arsenate of lead
reduced to three quarters of a pound to
fifty gallons of self-boiled lime-sulphur. The
same caution applies to the application Of
dust.
Early varieties should be sprayed two or
three times. Use the materials recon-
mended for first and second, or first, second
and fourth applications above, applying them
at the same time as noted above.
Directions for preparing self-boiled lime
sulphur, $780, follow:
Place eight pounds of unslaked stone
lime in q fifty-gallon barrel, and pour over
the shaking. AS the shaking starts, add
eight pounds of sulphur. Add water from
time to time toe keep the mixture from
becoming dry, but care should be exercised
not to drown the lime, which would cause
the shaking process to stop too soon. After
the mixture has boiled some five minutes,
cool off with water, strain into the spray
tank and dilute to fifty gallons. The mix
ture should be cooled off before the red
| streaks occur in the mixture to any extent
which is an indication of overheating. Avoid
Undertaking, however: Better results will
! be obtained by crushing all Jumps of sui
| phur and mixing it with little water before
adding to the shaking lime.
| The formula may be raised to 1616-1O0 or
used, however, in preparing self-boiled lime
| sulphur with these formulas. Stock, solu-
| tions can, of course, be made up, observing
| the proportions given.
Thorcughness in Spraying
| Without doubt great deal of the curculio
damage to the 1920 peach crop can lie
directly attributed to poor spraying. The
| fruit must be well covered on all sides with
the spray if satisfactory results are to be
obtained. The Importance of thorough
| spraying or busting by capable laborers
| under proper supervision at the right time,
| with sufficient number of outfits to Eandle
the acreage, is particularly emphasized.
| Above all, do this job thoroughly, and not
let it be a practice of merely shooting the
spray out Of the nozzle at the trees.
busting Schedule
AS soon as calyces or ''shucks'' start to
| split. making sure to complete the spraying
| by the time the calyces have shed. Arsen-
ate of lead, per cent; sulphur, so per cent,
| lime Is per cent.
Second Application
Two to three weeks after first applica ton:
Arsenate Of lead, per cent; sulphur, so
| per cent, lime 10 per cent.
Third Application
One month before ripening: Arsenate of
| lead, per cent; sulphur, so per cent, lime,
| 10 per cent.
Fourth Application (optionaD
l. Ten days to two weeks before harvest (if
| foliage and fruit show no important injury
Arsena1e of lead per cent, sulphur so per
| cent, lime IL per cent.
! Thoroughness is the key note of success
with dust as it is with liquid sprays. The
Importance of busting every tree row, in
| stead of every other row, or every third
row, is strongly recommended, and a good
! dosage must be given each tree
| Early varieties shod be busted two or
! three times. Use the same dust formula as
above at the time indicated for the first
| and second busting or for the first. second
| and fourth dustingS.
