SPRAYING— APPLE— CHERRY 
applications it is possible to combat several insect pests and fungous dis- 
eases with each application. Following are outlined complete spraying 
systems which are designed to control the principal pests of the different 
fruits. The four sprayings recommended under apple, as a rule, should 
be made regularly each year. The same is true of the peach. However, 
some of the fruits seldom require all the sprayings outlined in the system. 
For that reason, watch the trees and vines closely, and, where the pests 
are not present, the spraying necessary for the control of that particular 
insect or disease may be omitted. However, it is usually a gOod plan 
to spray with the boiled lime-sulphur in the winter, even though no San 
Jose scale seems to be present. It is very easy to overlook it, and, once 
it gets a start, it spreads rapidly. The lime-sulphur wash is not only good 
for scale, but for destroying a number of insect eggs. (For preparation of 
spray mixtures, see page 77.) 
The different sprayings necessary to control the principal insect and 
fungous diseases of the apple can be combined and applied so that four 
will be all that are necessary. 
First. The first spraying should be done in the winter or late spring, 
when the trees are dormant. Use boiled lime and sulphur. This is effect- 
ive against San Jose scale, oyster-shell scale, blister mite, and scab, and 
also destroys eggs of plant lice. 
Second. The second spraying should be made just as the leaf buds 
open, and before blooming time. This should consist of Bordeau.x 3-3-50 
and 2 pounds of arsenate or lead. It is effective against case-bearers, bud 
moth, and scab, and is especially important in the control of the scab, 
canker, and leaf spot. 
Third. The third spraying should be made just after the petals fsU 
from the blossoms. Use Bordeaux 3-3-50 and 2 pounds of arsenate of lead. 
This is for the scab, leaf spot, ease-bearers, and especially for codling 
moth. The poison should be directed, under high pressure of 100 pounds 
to 200 pounds, into the blossom end of the young fruit. The calyx closes 
shortly after the petals fall. For this reason the third spraying is most 
important for the codling moth and should be done as soon as possible 
after the petals fall. 
Fourth. The fourth spraying should be done ten days to two weeks 
after the third. Use Bordeaux 3-3-50 and 2 pounds of arsenate of lead. 
This is effective against codling moth, apple spot, sooty blotch, and bitter 
Careful spraying should be accompanied by good cultural methods. 
Keep down the weeds. Don't allow any brier patches, foul fence-rows, or 
half-dead, worthless fruit trees in the neighborhood of your orchard. They 
harbor insects and may infect the entire orchard with some disease. Burn 
all trimmings at pruning time. 
Cherry Spraying 
As a rule, the cherry does not require spraying as often as the apple. 
If no rubbish heaps, brush piles, or old dead trees are in the neighbor- 
hood, and ordinary care is given to cultivation, it will not be necessary to 
follow a complete system, except in special cases. 
First. The first spraying should be in the early spring or late winter, 
with boiled lime-sulphur. This is for the San Jose scale, Forbes scale, 
Putnam scale, the lecaniums, etc. The last two are not serious pests, as 
a rule, while the San Jose scale does not attack sour cherries to the same 
extent that it does other fruit trees. It careful examination is made of the 
orchard and none of these are found, the first spraying may be omitted. 
Second. The second spraying should be just before the blossoms 
open, with Bordeaux mixture, 3-3-50 and 2 pounds of lead arsenate. This 
is an important spraying, in the control of the rot, on the sweet cherries of
