ABOUT SPRAYING.
Provide for a Good Fruit Year BY
Fighting Pests.

The indications are that this year
will be what orchardists call "a good
fruit year" To insure the best yield
spraying should begin early. Spraying
for codling moth is begun when the
petals are fallen, and should be given
as soon as possible after that stage.
The calyx leaves are well open and
are uppermost, and 1t is essential that
poison be deposited there as the great.
er number of the early brood enter
the small apple at the calyx.
The small apple grows rapidly and
the second spraying should follow the
first in at least ten days. The larvae
that escape the first spraying will be
mature insects within short time
after the first apple has dropped, and
a spray should be given to protect the
fruit from the second brood. At in
tervals of about two or three weeks,
spraying for later broods has proved
profitable.
For bitter rot or scab, bordeaux
mixture applied before the buds open
destroy spores upon the bark and
twigs. II should be combined with the
second and fourth sprays for codling
moth, and II the disease has been very
serious, one or two more later spray
ings will be profitable. Other insects
and diseases have not been noted as
serious where spraying for cooling
moth and bitter rot have been applied
In some instances a single spraying
has secured a very great increase In
the quantity of sound fruit, but In most
cases single spray has not been sue
cessful in proportion to repeated
sprayings. The proportion Of sound
fruit on sprayed trees as compared
with unsprayed trees has varied in diff
ferent seasons, but an average for the
past six years in nearly so per cent
number one fruit from sprayed trees
a. less than ten per cent. from un
sprayed trees. The per cent. of mar
ketable fruit, including the second
grade, has shown slightly greater diff
ferences in favor of sprayed trees.
The cumulative effect Of spraying
has been noted in the greater free
dom from insects and diseases of the
experiment station orchards and vine
| yards compared with neighborint
plantations which have not beer
sprayed. The orchards have suffered
no injury from canker worm, leaf
crumpler or tent caterpillar, whicl
have been very numerous in neighbor
ing orchards during several seasons
The protection from fungus has beef
fully as valuable. During the season
1905-1906 practically no loss was occa
stoned by bitter rot, scab or rust
while unsprayed orchards in this lo
cality have suffered seriously.
In spraying peach trees to proven
brown rot and leaf curl the first spra
should be applied before the leaf bud
open. The foliage of the peach is nue.
more easily injured than is that of tn
apple, and after the trees are in lea
the bordeaux mixture should be re
duced to half strength.
AS the fruit reaches maturity tn
use Of bordeaux Is liable to discolo
the fruit. The colorless ammoniaca
solution Of copper carbonate has bee
used during ripening, but has bee
less effective than bordeaux.
The plum varieties differ consider
ably In their liability to spray burr
but as rule the bordeaux should b
diluted half strength for plums.
The spraying of the vineyard to PR
vent mildew has been uniformly su,
cessful The crops from unspraye
vines have in several seasons been a
most total failures when the spraye
vines have given fair crops.-R. !
