serrate, glandless. 1t has been no
ticed that it is especially bad on seed
lings in infested localities. 1t seems
hardly necessary to take out infested
trees as some have recommended,
but no doubt the seedlings above
mentioned could be disposed OF at
little loss to the grower and may
noticably check the spread of the
disease.
No extensive experimental work
has been followed out along the line
of determining remedies for this dis
ease; nevertheless knowing its habit
of growth and the action OF the var
ious sprays upon the peach, no fear
is entertained in recommending a
system OF spraying which will no
doubt prove effective in holding
peach mildew in check.
In his Fruits of California" Wick
son, on the subject of combating
mildew says:
"This has been effectually done by
thorough sulphuring. Mr.. klee ad
vises three applications where mil
dew is apt to be bad; the first one
very early in the season."
Owing to the smooth surface OF
the foliage OF the peach such applica-
tions would necessarily have to be
made early in the morning or after a
rain, while the foliage is damp.
Though the application is generally
a very simple matter when the dust
sprayer is at hand, it will not, as a
rule, prove as satisfactory as other
methods.
Lodeman, in his spraying OF
Plants" says:
at is probable that the disease
can be held in check by spraying the
trees with Bordeaux Mixture as soon
as the fruit has set, and following
this at intervals of two weeks by
two treatments of one ounce of car
Donate of copper dissolved in am
monia and diluted with twelve gal
Ions OF water"
Peach mildew being surface
grower there is no reason why any
of our standard fungicides might not
be employed in fighting it. A thor
ough spraying, before the trees come
into bloom, with formula A or c, is
recommended. After the blossoms
have fallen. an application OF B OF d
should be made. Following this at
intervals of ten days or two weeks
with one or two more applications
OF B or d. While A and E are some
peach while the tree is in full leaf
they are liable to burn the foliage
more or less and though it may not
prove dangerous to the life or health
of the tree, it is well to give up their
use for others that are safe as well
as efficient. Formula b is a modifi-
cation of the regular Bordeaux mix
ture sometimes recommended for the
peach, and can be safely used upon
the peach during the growing period.
Formula f is very safe and effec-
tive spray for the first application
before the leaves come out, but
others given are much more simple
in preparation and just as effective.
Formula A.-Bordeaux Mixture.
Copper sulphate (Blue stone or
Blue vitrioD, pounds. Quick lime,
4pounds. Water, 45 gallons.
Formula B.
Copper sulphate, 2 pounds. Quick
lime, pounds. Water 45 gallons.
Formula c.
Copper sulphate, pound. Water,
% gallons.
Formula D.
Copper sulphate, pound. Water,
400 gallons.
Formula E.
Copper carbonate, ] ounce. Am
monia enough to dissolve copper
carbonate.) Water, II gallons.
The effectiveness OF any OF these
sprays depends upon the thorough
ness with which it is applied, and
pains should be taken to reach all
parts OF the tree. A nozzle that
breaks up the spray well will save
much time. Fresh unslacked lime
only should be used. 1t should be
Stacked in water in a separate ves-
