Apple Rust or Cedar Rust is pre-
valent in several sections of this
county. 1t is a fungus diesase that
requires both the apple and cedar
tree for its continuance, and is a
common disease where apple and
cedar trees grow in close proximity
Rust spots appear on the apple
leaves in early summer; at first they
are small and of pale yellow color.

upper and lower surfaces. The coll
or changes in midsummer from
pale yellow to bright orange yell
low, and the spots may develop
CHI 80
mer the spots thicken or puff out
the lower leaf surface and become
studded with minute projections;
these split open and discharge an
abundant supply of spores. These
spores, like seed, will terminate
and grow, but cannot grow on
apple foliage. The only "host'' they
can make use of is cedar tree,
producing brown, corky gals COM
monty known as cedar apples"
These gals are slow in developing
and a cedar tree which becomes in
fected in July or August of one year
does not show any effects until Nav
or June of the following year. At
this time the young gals may be
seen as small green or greenish
brown engagements, and they do
not complet their development un-
til the next spring, when thew pro-
duce spores to infect the apple.
Note that the red cedar is the i'm
portant host plant from the stand
point of the fungus, for il lives
about II months upon the cedars
and only three months on the apple
Variations in the life history of this
fungus have brot about the produc-
lion of some cedar apples every
year, so that on the same tree NAV
sometimes be found cedar apples
which fruited the year before, other
which are then producing spores,
and some which are Just becoming
visible as tiny gals.
ne injury resulting from apple
rust is apparent in three WAYS:
Loss due TO infected and deformed
fruit; Decreased size of fruit; Loss
of vigor of trees.
Orchards can be kept free from
apple rust by first choosing site
where no red cedars exist: second
by cutting down and immediately
burning red cedars where they oc-
cur; third by planting varities that
are resistant to rust.
: Orchards within one mile of red
cedars are in danger of rusl at
lacks. If you have valuable or
chard infected by rust, start cam
paign for the eradication of all the
cedar trees.
Careful observations in various
apple orchards have led to a classi-
iication of the more important w.
