there are more failures due to un
timeliness and insufficient or poorly
applied sprays than all other com.
bined causes" In order of their i'm.
portance, this beetle expert sum.
med up the most important steps fol-
the property owner to follow in his
plan of checking the beetle and pro-
tecting his plants and trees as fol-
lows:
1-Spray the trees and plants be-
fore the beetle arrives.
2-Put on enough of the spray to
cover all sides of the leaves.
3-More foliage has been ruined
by too little spray than with an
overdose.
In explaining the latest recon-
mendatiOns for spraying against the
beetle, he states that very few
changes have been made in the rec
concentrations from last season. OBJ
servations made in 1929 show that
with but few exceptions it has been
impossible to make any improve
ments on the materials or formulas
that have been recommended in the
past.
Lead arsenate for fruit trees and
the lead oleate coated arsenate OF
lead for shade trees, ornamental and
non-fruiting trees, constitutes the
most important sprays now on the
market. A few minor changes in
the amounts of material to use on
certain kinds of plants have been
recommended for this season, con-
tinued Mr.. Smith.
"Follow the direction on the label
of the can or jar which contains the
spray poison and satisfactory results
can be secured" declared the speak
er. BUY the spray from a reliable
house, follow the directions outlined
which are those recommended by
the Beetle Laboratory and get it on
the. bush. or tree before the beetle
arrives and little trouble need be
| feared this season." said Mr.. Smith,
in summing up the spray program
for the average property owner to
follow. Tell your readers to get the
spray on before the first beetle ar
rives," emphatically states the rep
resentative of the Beetle Laboratory.
"It takes no more material to pro-
| tect a fully foliated tree before the
beetle arrives than afterwards and
in the meantime they will be able to
drive the first beetles away or kill
them in their first feeding"
Beetles attract beetles. The four or
five beetles that may be found on a
tree early in the season may not
cause much injury to the foliage, but
these few beetles are likely to at
tract hundreds of others and before
many days the foliage may be en-
tirely stripped from the tree or
plant.
Flowering plants still continue to
be the one drawback to the general
recommendation for spraying
against the beetle. No spray has as
vet been devised that will keep bee
ties away from the blossoms of our
finest plants. The presence of the
spray on the leaves or the petals is
offensive to the eye and even then
does not fully protect the bloom as
it is continually changing from the
tightly closed bud to the widely
spread petals. Work is being car
ried out on the development of a
repellent for the flower garden
which will drive the beetle away and
not be offensive to the owner or the
neighbors, but that problem still re-
mains unsolved. The entomologists
however, hope to find that solution
in the near future. They have been
working on it for some time and
have found much interesting infor-
nation about the likes and dislikes
of the beetle.
For the home owner who is plan
ming to spray his garden and trees,
the following recommendations are
made by the staff at the Moorestown
Experimental Laboratory:
On all ornamental and shade
trees, including the Chestnut Oak,
Pin Oak, Norway Maple, Japanese
Maple, Sycamore, White Birch, Lom-
hardy Poplar, Willow, Elm, Orna-
mental Plum and Cherry, Linden,
Sassafras, Horse Chestnut, Cypress,
Larch and Copper Beach; Ornamen-
tai Shrubs, FlOwering Ounce, Spir-
ca, Hawthorne, Althea, Hollyhock,
Rose, Virginia Creeper, Aster, Can
ma. Dahlia, Privet and Barberry;
Non-bearing apple and cherry trees,
non-bearing grape vines and nom
bearing Raspberry and Blackberry
bushes,-apply coated lead arsen-
ate, 2 level teaspoOnfuls per quart of
water or two pounds to Is gallons of
water.
Bearing Cherry, Raspberry, and
Blackberries should not be sprayed
until after the fruit is picked. Ap-
ply then coated lead arsenate, 2 lev
ell teaspoonfuls per quart of water
or 2 pounds to 25 gallons of water.
Spraying is not recommended for
varieties of raspberries and black
berries maturing fruit throughout
the beetle feeding period.
Grapes should be sprayed from
top with one level tablespoonful dry
lead arsenate and 2 teaspoonfuls
household wheat -four per quart of
water, or IL pounds of dry lead ar
senate and / pound -four to rs gal
