PETROLEUM AND THE FRUIT
INDUSTRY

The remarkable developments OF
science and industry almost daily,
Furnish unusual and interesting new
contacts in the business world
New products are locating markets
lin unexpected channels, and there
seems no end to the adaptation Of
srltiustry's output to Mans needs.
/ The fruit grower OF thirty years
/ ago never suspected that he or his
;ons would be dependent on the pc
Itroleunl industry for success ir
large orcharding operations. The
laay has arrived when the horticui
tturist would be seriously handicap
Iped ! If all petroleum products were
denied him. Gasoline, lubrieating
oil ard grease for sprayers and trac
Tors; incl oil for orchard heaters ir
sertain spring frost danger zones;
piled paper for prevention Of scald
IN storage apples; and misciDle oil
and emulsions for spraying consti
ute most interesting developments
and adaptions OF one Of natures
lproducts.
Orchard heating as an occasional
protection against late spring frosts
is provided in many sections when
valuable crops are subject to frost
damage. Particularly in the west,
orchard heating with fuel oils or dis
Itillates has been adopted widely and
lprofitably.
| Gasoline, lubricating oils and
greases for power sprayers and dust
srs have become absolute necessities
lin orchard and fruit protection,
without which growers would be ser
liousIy handicapped.
Oiled paper wrappers and packing
i have shown remarkable value in pre-
venting ssscald'' of apples, particu-
| iarly certain tender green and. yellow
varieties under storage conditions
hereby enhancing their market
value and keeping qualities.
4 A half century has elapsed since 9
petroleum product, kerosene einul.
sion, was introduced and recon-
nlended by the entomologist Of the
i u. S. Department Of Agriculture fer
control OF certain scale insects
Since that time remarkable changes
ifhave developed in the manufacture
Of the many derivatives of petroleum
and certain OF these have come into
very general use for the spray ing OF
|trees, shrubs and plants for ady
control of certain pests.
i The rapid and serious spread Of
apple leaf roller into the for western
| orchards soon forced the growers to
use oil sprays at eight to ten per
cent emulsion strength: and fortu-
nately when properly and thorough
i ty emulsified these oil sprays have
caused no cumulative injury
Broken down. or separated oil
| emulsions, often homemade, have
occasionally caused serious damage
i About eight years ago a wide
spread serious infestation of San
lose scale appeared in the MISSISSIPPI
1 oi Valley States which lime-sulful
solution Ii ed to control. Again
the miscibIe oils and oil emulsions
saved the orchards, although thous-
i ands Of trees were on the verge OF
destruction.
i Orchards in the New England
j States, Nova Scotia, Ontario and sew
sral other northeastern states are
| now suffering much injury from at
] ltacks of the European Red Mite,
which damages the foliage causing q
bronzy or sickly condition interior
ing with the usual leaf functions.
i Miscible oils applied in the delay
| cd dormant stage have given better
kill OF the winteYing eggs than
1.-THE lighter ell emulsinos and have
i come into general use at this stage
for control or scale insects and g
heck on aphis as well.
Petroleum miscible sprays seem
destined to supplant the old dis
agreeable caustic lime-suIfur as a
lfungicide are moving efficient
The home-m mixing of oil emulsions
is always attended with uncertain
ties regarding the oil, soap and hard
water difficulties and is not generally
recommended. A miscible oil made
| by a reliable manufacturer is usually
more dependable and uniform in
EQUALITY.
Unless man honestly tries to Inn
rove himself and his work each day
ne does not know what real happi-
ness is.
