the mature beetles are the most IN

Control Measures in Stone fruit.
Arsenic spraying is thus far con-
siGeFed the most important means Of
controlling the plum curcullO. All
stone fruit tress are very sensitive
% free arsenic that might be in the
insectlcide. Since Paris green con
tains three to four per cent free or
so!uah!e arsenic, it is better never
TO use this poison on peaches. Ar
senate CT lead is now manufactured
with so little of this dangerous form
CT the arsenic that it rarely burns
the foliage at all, and then only il
wet seasons. The most important ap.
Iiications for this pest are two pounds
CT arsenate of lead paste, or one
pound OF the Vreeland powdered form,
in 30 gallons of water or self-boiled
lime sulphur wash, the first spraying
being done soon after the shucks are
Oft the trees, and the second spray
ing in two or three weeks later with
the same mixture. About four weeks
before the fruit is ripe, spray again
with the self boiled lime sulphur wash
without the arsenate of lead Some
growers have made three full appli-
cations OF arsenate of lead at the
strength above given without any
injury to the foliage or crop. This all
depends on the weather conditions
Such favorable results with arsenate
OF lead on peaches were obtained
when the season was not especially
rainy. 1t is better to be cautious,
particularly in damp seasons Here
is point where the individual or
chardist can we'll afford to experiment.
Better lay Off a portion OF the or
chard for third spraying with the
arsenate OF lead, and keep a writ
ten record OF what trees were actu-
ally SO treated. Then you can CON-
pare these with those that received
only two applications, so as to make
sure whether the third application
caused any injury and had any eff
feet on the last worms that appear IN
ripe peaches.
Seif-boiled lime sulphur wash is
made as follows:
4our sulphur .................S lbs.
Good stone lime ....S lbs.
wafer .............. 80 gal.
First slack the lime with a little
water in a barrel While stacking
add the sulphur and Stir the mixture
well so as to get the lime to cook
the sulphur while it is stacking. Then
add water to stop the heat as soon as
the lime is well dissolved by the pre-
cess OF stacking. If the water is not
added within Is minutes after the
stacking is done, the sulphur VIII
form sulphideS that are injurious to
peach foliage. This is especially
likely to happen, if the lime is extra
good and Stacks fast. 1t is safest to
add plenty OF water just as soon as
the lime is we'll Stacked, and take no
chances. The arsenate of lead will
turn the mixture a sort of brown color
as soon as it is added, but this does
not in any way effect the value OF
either the lime-sulphur wash or the
arsenate. The commercial lime
sulphur wash greatly diluted has vet
been shown to be of the same value
as fungicide to control the peach
rot as the self boiled lime sulphur
wash. We are therefore advising the
use OF the last named wash only for
peaches.
The most important preyentiyes
or methods of caring for an orchard
that effecutally reduce the number OF
curcullos in the immediate vicinity
is yearly pasturing of the orchards
with swine. Hogs are very fond of
fruit, and If enough are allowed TO
run in an orchard while the
falling in April and May and are not
removed until the crop is gathered.
they Will keep the majority of the
Sfubs In the fallen fruit from ma.
turing into beetles. 1t is also neces.
sary to cultivate the orchard several
times during the season six weeks
after the blossoms fall to destroy
many of the tender pupae in the soil.
clean culture in and near the or
chards tends to keep the curcuios
from getting through the winter alive.
