Paul G.. Kruger, who has been
working on the apple rosette in an
orchard near North Yakima, in which
he has met with particular success
has brought to the Herald office re-
Gently, was asked to explain his
method of treatment.
That he has been successful Is
shown by the almost incredible
growth that the trees secured after
treatment, when the trees sent out
their leaves normally, and apparel to
take an entirely new lease on life.
The following is Mr.. Kruger's eA-
PLANTATION of the trouble ao1 MS
method of cure
This subject has been under my
observation during the entire sum-
mer, the same being condition caus.
ed from careless handling of the
orchards. Various causes have
brought about this condition; among
the most prominent are: Too much
water, careless barking of the trees
with the single-tree of cultivator or
pillow; poor pruning, leaving cut
exposed without covering the same;
taking humus and nutrition away
from the land by the crop raised
between the rows of trees thereby de-
priving the trees of the most essen
tial elements.
Thus rosette I would class with
blight conditions. 1t is a condition
or disease which can be overcome by
a strict attention to the trees. How
ever. an orchard may be entirely
ruined by allowing the condition TO
continue.
Examination
After careful examination and
working on trees affected with this
condition, l found several causes ex-
listing in an orchard on Selah extern
sion, Selah r. 2, being IL are
tract l found the owner of this or
chard had used up all the humus
and nutrition of the soil by raising
potatoes. and having made no pro-
vision to reimburse the soil, it could
not feed the tree with sufficient food
for its development.
The disease is more prevalent in
orchards which are rapidly grown
and in a succufent condition.
would advise to reduce irrigation to
a minimum. Authorities say that
there are now within the boundaries
of the irrigated west about 100000
acres of irrigated lands that have
become almost worthless on account
of seepage or what is really the
same thing, by having valuable wa
ter wasted, until now the whole land
has become saturated and useless.
a careful inspection of the trees
showed barking of the trees with the
single-tree while cultivating. Thus
we find the layer of tissue or the Gu
ticle broken.
/ also found cuts made by the
pruning saw not covered with wax
or paint, thereby not giving the
sap the free flow necessary for the
welfare of the trees. With these
conditions confronting me 1 went to
work. On June I Il began spraying
this orchard with self-boiled lime
and sulphur solution and crude car
bolic acid, carefully going over each
tree. making the strength of the So
luton LOIS by hydrometer tests. At
this time the trees in the orchard
looked almost bare of leaves. I also
had the owner begin to cover every
bruise and open cut on the tree with
an especially prepared paint consist
ing of shellack, beeswaX, rosin, lin
seed oil (boiled) and white lead. The
object in this painting was to keep
the sap from oozing out
On July II | again visited this orr
chard with the intention of pruning
the same. The spraying and cover
ing of the cuts had worked satisfac-
tory to me. 1t could hardly he other
wise. When we consider that the
life-gving fluid of the tree was be-
ing wasted by oozing out of the tree
and becoming a harbor for all kinds
of fungi. Is it any wonder that
such trees will not leaf out? How
long do you expect to be healthy with
your blood oozing out, and it being
allowed to become a CONCEALED mass?
Do you think you would be able to
grow very many healthy leaves and
buds in this life? What do you do?
At once you go to a physician and
have your wounds attended to and
an open cut is closed properly. Well
your trees demand the same kind OF
treatment More covering up Of
cuts, cut out the end which you al
lowed to remain by not cutting close
to the limb of the trunk. Give your
orchard a chance and you will be
contented and happy.
As stated above. my second visit

trees. | pruned, thoroughly covering

IN summing up the entire matter
regarding rosette. I would be derelict
