CALCIUM ARSE|NATE
BEST WEEV|L CURE

That it is possible by the proper
use of calcium arsenate to control
the boil weevil and grow cotton sue
cessfully in spite of the boil pest,
although it is impossible to COM
pletely eliminate the weevil, were
points made by DR.. George A. Ma
loney, boil weevil expert for the
United States bureau of entomology,
in an address Wednesday morning at
the annual meeting of the South
ern Fertilizer association at the Pied
mont hotel.
Complete elimination of the boil
weevil," said DR.. Maloney, ''as de-
sirable> as it would be, has been
found to be absolutely impossible.
There is no insect that we know Of
that is so resistant to control meth
DDS as the boil weevil. The United
States chemical warfare bureau, aft
er many exhaustive tests, have been
unable to find a single toxic that
would eradicate the pest without in
JuIing both human beings and
plants.
1.-THE bureau of entomology has
spent many years in experimenting
to devise some efficient and econom-
ical method for controlling the boil
weevil, and today we know that cal
cium arsenate is the only poison
that will do it. 1t is today the last
word in boil weevil control.

How to Apply Remedy
DR.. Maloney went on to say that
it is not advisable to poison the
plants early in the spring for the
reason that all of the weevils that

ments that early poisoning is not
economical"
He cited many instances where
calcium arsenate had been used to
increase production anywhere from
$50 to 1000 pounds per acre, but
said that it was not advisable for a
farmer to use it unless his land was
sufficiently fertile to yield at least
half bale of cotton per acre. He
pointed out that where land was
not naturally fertile it should be
heavily fortified in order to Ing
crease it's normal yield. "Then,S
he said, "the poison can be used
economically to eliminate the weevil,
but unless the normal yield lis suf-
ficiently large to justify it's use the
expense will be too great.
Tribute to Association
j. Russell Porter, president Of the
Porter Fertilizer company, of At
lanta, and president of the Southern
Fertilizer association, presided at the

ment committee.
Other speakers at the meeting were
