District Inspector r. q. Morrison Of
the department of State Commissioner
of Horticulture Huntley of Washing
ton, IN a statement to the Herald
makes a number of spray suggestions
which ought to- be helpful at this time
to fruit growers, rose culturists and
others who are engaged in the de-
velopment of plants, trees or veg
etables. Mr.. Morrison says
~ have been getting inquiries in re-
gard to the effectiveness of; different
sprays for peach aphis. rose aphis and
the black aphis of the cherry. The
following will help TO answer some Of
these:
whale oil soap. l believe, is one Of
the necessary constituents of our best
contact sprays, in fact whale oil soap
alone dissolved in water makes A
fairly good spray. A number of very
good sprays can be made by mixing
whale oil soap with either sulphur.
cresol or with black leaf 40. or with
one or more of these materials. which
in the right proportions increases the
effectiveness of the spray. For green
aphis in apple trees spray made bv
mixing three pounds of soap dissolved
In hot water with Is pounds of flowers
of sulphur to each so gallons OF water
makes very efficient spray. This So
luton has been used at the Colorado
experiment station for a number Of
seasons with good results for aphis,
brown mite and red spider.
Another Good Spray
Another good spray can be made
from whale oil soap and cresol as fol-
lows: Soap pounds, cresol 10 to IL
ounces, so gallons of water agitate
thoroughly to keep solution of uniform
density.
The black aphis Of the cherry is
probably most resistant to sprays OF
any of the aphids, and ordinary SPRAYS
which will kill green aphis are not al
ways effective on the black aphis
For the black aphis of the cherry
and also peach aphis the following
spray mixture when properly mixed
and made has given very good results:
Three pounds whale oil soap. ounces
cresol, ounces black leaf 40 and
water to make so gallons of spray So
luton. The mixing of this solution is
important as the effectiveness Of the
material largely depends upon q
thoroughly mixed solution. For a $50
or 200 gallon tank multiply this for
mula by three or four, as the case
may be. and 1t will be a convenient
amount to mix at one time.
How Mixture Is Made
dissolve the soap in four or FIVE
gallons OF hot water, add the cresol
and stir thoroughly, then pour the
mixture into the spray tank and start
the agitator. stir the black leaf 40 In
a few quarts of water preferably
warm and pour into the tank and
have the whole amount well agitated
before spraying.
"a few men have contended that
the vermorel nozzle with high pressure
is more effective than bordeaux
nozzel with coarse spray. for the
reason that the high pressure with the
vermorel nozzle breaks the spray par
ticles into very fine mist which gives
off fumes and acts as a fumigant
rather than as a direct contact spray
In actual test, however, with the same
spray material the bordeaux nozzle
has given better results by forcing tho
spray directly into contact with the
insect. Pressure Is necessary to reach
all the insects, and to get the best re-
suits the applications should be made
before the leaves begin to curl or 1t
will be almost impossible to reach all
the aphs after the leaves have curled
up.
Growers Much Interested
Assistants Hunter Powell anil
w 500 inspections of orchards with
the owners, report an unusual amount
of interest among the growers just
now. Mr.. Powell, who has been work
ing In the vicinity of Sunnyside. Out
look and Grandview, has found The
conditions much improved over what
thy were a year ago. There has been
a fairly heavy crop OF pears in thar
district and a good thinning of the
Stamen Winesaps as well. However
1t is the common opinion that the pear
crop Will be heavy enough.
THE assistants have been very busy
since they began work in April, and it
Is our ann to do the work as syste-
matically as possible and at the same
time answer calls, which amount 20
several hundred each month. After
this month only two assistants will be
! used to comply with my agreement
with the county commissioners. | ap-
preciate very much the assistance and
cooperation we have received on the
part of the fruit growers in general
and still more of it will enable us to
do more and better work for the fruit
growing interests.
