FRUIT GROWERS
ARE GIVEN ADVICE
ABOUT SPRAYING
continued from first mage,

In these spray suggestions of
March rs DR.. Adams recommends
that the delayed dormant for apples
should be completed by the first
week in April, as such varieties as
the Early Ripe, Nero and Dutchess
are showing opening of blossom
buds resulting in their being in a
receptive stage for this particular
spray. The later varieties will fol-
low rapidly under normal weather
conditions. The green aphids have
Matched and are found on the open
ing blossom buds, but not as nu-
merOus as observed the past two
years. Where heavy infestatiOn Of
scale, aphis, and red mite occur it
is advisable to use the miscible oil
or oil emulsions at the recommend
ed strength, and for the control of
scab the commercial lime sulphur
or commercial sulphur compounds
that are recommended by the manu-
facturers must be added, as the oil
sprays alone are of no protection
for apple scab. Where light in
festation of these pests occurs, the
growers are advised to apply the
commercial lime sulphur testing 80
degrees Baume at the rate of 90
gallons to 1SO gallons of water for
a spray tank of 200 gallons capac-
ity,
The early blooming varieties of
peaches are showing pink buds. and
with the temperature ranging above
65 degrees there will be a rapid
opening and development of these
buds within the next few days. In
the event of q continued period of
cool, wet weather at this stage,
blossom blight may become prevail
ent, and the peach trees should be
sprayed with dry-mix at the rate of
so pounds to 200 gallons of water,
or busted with the 1920 sulphur
and lime dust.
The problem of fertilization is of
vital importance to practically every
Orchardist, and this subject should
be considered carefully and COM
pletely analyzed with regard to
growth conditions and requirements
of the individual orchards. Accord

is a lack of available nitrogen in
practically all orchards in the state |
to permit the trees to perform their |
fullest function. If the foliage on |
the trees last season was pale green |
in color. and if the leaves on the |
apple and peach trees dropped early |
in the fall. or if last years twig |
growth was short and the spur |
growth also short and slender, in |
all probability these particular
trees need nitrogen.
In a season when there is a great |
price differential between the cost |
of nitrogen. as between sulphate of |
and fertilizer for apples, |
it must be remembered |
that sulphate of ammonia must be
applied about a week earlier than
nitrate of soda. Sulphate of am
mOnia must be applied about a
week earlier than nitrate of soda.
of ammonia also has the
disadvantage in that it does not
become completely available before
the spur growth has ceased for the
season, consequently it would not
be advisable to use this form of nj
trogen on apples year after year as
a substitute for nitrate of soda. The
sulphate of ammonia, however, is
most likely a safe source of nitrogen
for peaches, and may be used in
stead of the nitrate of soda, but
both of these fertilizers should be
applied as soon as the trees show
Indications of starting activity in
the spring. In those orchards in
which the trees have been bearing
we'll and have good foliage color
with a subsequent good growth, it
IS advisable to use acid phosphate
rather than the nitrogen alone, ac-
