Solution.
Use a bordeaux nozzle, sometimes
called "clppernozzle,' CT the Friend
nozzle. using 80 to f., degree bend
connection to the rod. Cut down the
hcle until it throws a fine but force
full mist four to five feet from the
nozzle Keep the solution well agi-
tated as the sulphur tends to rise to
the top Agitate 10 or II minutes
before starting to spray.
Action of Remedy.
The flowers of sulphur acted upon
by warmth of air oxidizes, giving off
fumes that slowly kill the spiders.
The young ones die in a day or two,
but some of the older ones live a
week or ten days.
The soap is necessary to keep the
sulphur from rising to the top of the
solution and enables you to keep the
mixture at an even consistency. 1t
also Keeps the spray from forming,
so freely, the drops that fall from the
leaves easily. The tendency is rath
er to form a film on the leaves.
The flour paste makes the spray
stick so that it has an action, over
period of three to five weeks or
more, sufficient to kill all the living
spiders and the future young as they
hatch from the eggs that are deposit
ed at the time of spraying.
Caution.
Don't vary, however slightly, this
formula as it's action is easily
changed.
Don't spray this on the ground
in large qualities, or use it in a peri
cd of damp weather on the foliage
without the addition of one and one
half gallons of the commercial lime
sulphur stock solution. Much moist
ure and warmth over a period of
number of days is apt to cause the
formation, from the flowers of sui
phur, of the injurious quantities of
free sulphuric acid. The addition
of the cooked commercial solution
neutralizes this forming acid.
Keep up a pressure so that it is
driving and rather narrow spray
when leaving the nozzle. This is
necessary in order to break the webs
and be sure to thoroughly cover the
leaves under the webs with the solu-
ton. AS most of the webs and mites
are on the under side of the leaves,
the spray must be directed upward
from around the base of the branch
Spray so as to be able to say that
each infected branch has been spray
ed thoroughly from two or more
sides and at such an angle that the
lower leaves do not protect the ones
three years old or older, get the noz-
zle inside the tree and spray the side
opposite you very carefully, as we'll
as the inside limbs of the tree. Just
before moving around to the next
quarter of the tree go carefully but
more quickly over the upper surfaces
of the leaves, that you just treated
from below This advice comes from
California. where the long warm
summer of about six months causes
the spider to thrive and do great
damage. One careful treatment is
sufficient. There they find it the
hardest to effectively reach the pests
by spraying. The usual methods of
going over a tree do little good.
Keep all weeds and vegetation
from under the trees and away from
the fences following late treatment
Of the trees) as they afford a place
for the eggs to hatch the following
spring and a feeding ground in case
Of perenials.
The common orchard grass found
IN our Wenatchee orchards is a
breeding place for the spider, and
unless this grass is kept out of the
orchards it will harbor the red spider
from year to year in infested or
,hards.
During the fall the red spider will /
20 into the ground near the trees.
Some of them are down five inches in
he ground already. l am expert
nenting to get a solution that can
1e put into the ground and kill them
Ill when they go down. Am getting
some gratifying results and hope to
perfect the formula in time to get
hem this fall
1t is clearly evident that this is the
most vulnerable period to attack
hem when they are all gathered into
small space in the ground. If this
an be effectually done there Will be
zone to ascend and repeat their dam
lges. The eggs that winter over on
he trees must be killed in early
pring.
