the finger nail to a squirrels ear, use
lime. sulphur Ills, l-20, l-25 or l-SO.
Burning Of foliage 10 quickly apparent
ana should such burning occur to any
great extent. 1t is advisable to use
weaker solution Bordeaux, which is
regarded as one of the best funRicides,
may be used IN this spray at the fol.
lowing strengths: $3.50 or 4-4-50.
This spray may not be necessary
every year. However, it is very good
insurance for clean crop even in the
years when fungus infestation does not
begin to appear until later, for the fol-
lowing reason:
lst. In the next spray. the pink
spray, it is difficult, especially in large
orchards, even when beginning early,
TO spray the entire orchard before the
PINK buds have opened out almost in
full bloom.
End. Rain may come and interfere
with the pink spray or delay il, there
fore 1t seems advisable to recommend
this semi-dormant spray, and there is
an additional reason for putting on this
semi-dormant spray, which is, should
your work lack thoroughness in the
semi-dormant, the overlooked limbs will
more than likely be covered in the next
spray following, which is the pink
spray.
.3rd: In the pink spray use lime sui.
phur l-20. l-25, 1-30 or l-35. The good
results in complete spraying program
have been secured with lime sulphur at
strength of lao. II there is any
burning OF foliage, pinching of leaves
or stunting that looks serious, use a
weaker solution. This spray should be
commenced very early when the pink
does not look much larger than a pin
head. especially il the orchard Is one
which is large enough to require sew.
eral days in which to put on this spray.
Bordeaux seems unwise on account of
the russetting produced in 1914 and
1915. Russetting is almost certain to
appear on fruit later if rain follows the
application of Bordeaux at this season
of the year.
Atomic sulphur. from observations
made this year, did not show as high a
percentage free from scab when an.
piled, as lime-sulphur did. In the pink
and calyx sprays growers feel that cool
weather prevents the sulphur in atomic
sulphur from volstilizing. 1t also must
be admitted that when atomic sulphur
was used this year, in most instances it
was applied at 6 or 8 pounds to 100 gal.
Ions. Recommendation call for IL
pounds to the 100 gallons in order to
secure satisfactory results from the use
of atomic sulphur for fungus.
4th: Calyx spray. lime-sulphur 1-30,
1-35 or lao, and arsenate of lead. This
spray should be applied when the calyx
has opened and the lobes upright or at
an angle, both for scab and codling
moth.
Bordeaux is generally liable to rus.
set apples at this time and is almost
sure to do SO if rain follows soon after
application.
| The same remarks apply to the use
of atomic sulphur in this spray, as
have been already made under the head
of the pink spray. However, if'trouble
with powdery mildew should occur, use
atomic sulphur or iron sulphide in this
spray for the control of this disease.
IL the grower feels there is greater
danger of burning in the next spray
from lime-sulphur than from atomic
sulphur. he can use atomic sulphur IL
pounds to 100 gallons. which should be
begun in the calyx spray. or he can
probably use, obtaining satisfactory
results without great risk, lime-sul-
phur 1-35, possibly preferably lao and
atomic sulphur pounds to 100 gallons.
One grower used this cOmbinat ion
last year with good result and no dam
age, FL.
1t is important here to call the grow
er's attention to the fact that il he in
tends to use atomic sulphur in the 10
day spray or later sprays, that unless
he begins the application of Bordeaux
In the calyx, over stimulation may re.
suit from the use of atomic sulphur,
causing shedding of foliage and drop
ping of fruit.
Growers also must not forget that in
using atomic sulphur applications
should be made SO as not to allow q
longer period of time to elapse between
applications than 10 days or two weeks,
for the reason that the shedding of fol.
iage or dropping of fruit may result.
9Th: 10 day spray. lime-sulphur 1-30
1856 or lao or atomic sulphur if used
previously in calyx alone, or combined
with lime-sulphur.
9Th: Second codling moth: Abou,
June 1st to 18th, according to season
use arsenate of lead. The use of fun
gicides at this time will depend largely
. on the amount of infestatOn of fungu:
in the orchard. Atomic sulphur can bs
used If it has been applied previously
for calyx and 10 day sprays. Lime-sul
phur should be used with caution fol
the reason that at this time of year
particularly if the weather is hot, i
has caused baking of the apples il
wears past. If lime-sulphur is used ]
seems advisable at this time to recon-
mend that weaker solutions be used
and even with weaker resolution ther'
may be some baking of the fruit if th'
weather is exceedingly hot. Bordeaux
may be used at this time in the Secont
Coldine Moth spray at $3.50. or 4-4-5O
, possibly as strong as $3.50, but no
until the hair or down on the apple ha
entirely disappeared. and the skin be
comes tough and hard.
7tb: Spray about June goth. Bor
deaux may be used at $3.50 or 4-4-5

( orchard is already infested with fun
