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 cooling 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 a short time
after the first apple has dropped, and
a spray should be given to protect the
fruit from the second brood At in
tervaly 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 If 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 codiing
moth and bitter rot have been applied.
In some instances single spraying
has secured very great increase In
the quantity of sound fruit, but In most
cases single spray has not been sue
cessfui 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,
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
t dom from insects and diseases of the
/. experiment station orchards and vine
q yards compared with neighborine
/. plantations which have not been
e sprayed. The orchards have suffered
b no injury from canker worm, leaf
crumpler or tent caterpillar, which
have been very numerous in neighbor
ing orchards during several seasons
| The protection from fungus has beer
| 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 10
/ 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 muc
i more easily injured than is that of tn
/ apple, and after the trees are In lea
| the bordeaux mixture should be RI
| duced to half strength.
/ AS the fruit reaches maturity th
use of bordeaux is liable to discole
the fruit The colorless ammoniae;
solution of copper carbonate has bee
| used during ripening, but has bee
| less effective than bordeaux.
/ The plum varieties differ conside
I'D ably in their liability to spray bur
but as a rule the bordeaux should
diluted half strength for plums.
1g The spraying of the vineyard to pr
In vent mildew has been uniformly su
ge cessful The crops from unspraye
m vines have in several seasons been {
nd most total failures when the spray
vines have given fair crops.-R.
