SHUN LIQUID SPRAYS FOR ',r:
POISONING BOIL. WEEVIL

A warning against liquid sprayel
attachments; ITO cotton poisoning
machinery is issued by b. R. Coad,
director of, the&boll weevil laboratory
of the United States psHastment OF
*Agriculture. Calcium sassenate ap-.
piled as a dust, he DoinfNlt, is the
only certain means yet hha; for con-
trolling the boil weevils eff;
fort at control by mead8ef liquid
sprays is useless. spraS attach
ments are, therefore, nonay un-
necessary but are an Esad5 burden.
They increase the cos 8he. ma
chinery and make it more conlpli-
Gated and difficult to operate. The
liquid spray, even if itwela. as et-
fective as the dust Msthod Eould be
decidedly more .expensiK# woult,
necessitate the~use Of Xterfarts, te
!, feed the machines, wsu aand an
ample and constant water supply
which is not available on most
farms, and in various ways would in
crease the cost of poisoning opera

fective method Of controlling the boil
weevil is the dust method and they
should not waste times afa money
Mr.. Coad points out,@ exaWiment-
ing with the expensive Fssska@ meth
DDS that farmers in oths. liaes are
so constantly trying toy get M:,awaH
;; from.
In addition to the foregoing spray
ing equipment we also find on the
market many curious. ..deyiees fpr eap-
! ! plying some liauid. prenatMign us
ually containing celeiuh & Fsenate
for the control Of the boil weevil.
Some of these are to be attached to
plows, others to cultivators, while
still others run independtseHe1y. They
are usually proyiasd wlaHome ex-
ceedingly simpleg form of.4aAk with a
gravity flow Of n fa,1lAs Whkh either
dropsTs..on the plants fof, is Swiped on
them by, some, form Of Drushes or
rags. Many such implements are
absolutely comical, and the only sad
feature is the fact that some farmers
are foolish 7eneash, to purchase: them .
The: literatug9 amertising these i'm
splements promises wonderful results
t'and: the j directions given often eHl?
!, for only assmaii fraction o4 pound
of poison per acre, which is dis
tributed over the plants in very
! irregular manner. To expect boil
| weeyil" control from such methods s
absolutely absurd. The Depart
nent specialists have been attempt
. ing boil weevil control with liquid ap.
plicatons for many years. In these
! tests they use the finest aVaila bic
high pressure spraying aachinery
distributing the liquid poison over
the plants in mist form, thus reach
ing absolutely every part !: of the
plant. Furthermore, these applica-
tions are usually: made at: the rate OF
100 gallons of. solution per- acre In
spite of this these spray applications
i 90 not control the boil weevil... and
how can anyone expecta to secure
enefit from the absurd recommends
tions issued with some OF, xthe ma
, chi1res now offered the farners?
