Spraying in the Spring and Summer

dormant spraying of fruit trees, likewise
later spraying for protection and pre-
vention.
The following spraying programmes for
Spring, Summer and Fall, have been
found to be efficient and satisfactory both
in Washington and Oregon and are rec
commended for Western Washington Or
chards.
Apples and Pears.
1. In the Spring just as the tips of the
leaves are emerging or just before. Slight
injury may occur to the tips of the first
leaves but this is not serious.
Lime sulphur, Ito or ~; black leaf,
40, 1900. Dilute lime sulphur and add
black leaf 40 at the rate of / pint to 1870
or 125 gallons of spray. This spray Is
for MOSES, lichens, scale insects, aphis,
pear leaf blister mite and red spider.

arated in the cluster and show pink:
Bordeaux, $3.50 or lime sulphur, 100,
preferably the former.
Lead arsenate, paste form, 2 pounds, or
powdered, l pound to SO gallons of di-
luted spray. Black leaf 40, $1,000 if
aphis is present.
This is the first scab spray and will
control the bud moth If the Fall spray
has not been applied, and also the tent
ca~terpillars and other leaf eating insects.
The lime sulphur will also kill the red
spiders if any are present.
8. Just after the majority OF petals
have fallen:
Lime sulphur, 1870.
Lead arsenate as under No. 2, II bud
moth or leaf-eating insects are present.

If anthracnose Is serious or has pre-
viously affected the fruit, use Bordeaux
at this time. 1t has been found in Oregon
that this is the best time of the year to
kill the bud moth. Lead arsenate should
be applied If it has not been controlled
by other sprayings.
6. After the fruit Is picked:
Bordeaux, $3.50 or lime-sulphur, Lilo.
This spray is for the control Of apple
anthrocnose and should be applied i'm
mediately after the fruit is picked. Lime
sulphur may control it, but Bordeaux is
certain to. If the disease is serious, apply
again in about W weeks.
