FURTHER EVIDENCE ON BOIL
WEEVlL POISONING WITH
CALCIUM ARSENATE-f GLASSES

Test No. 3:Samc mixture was used
on test No. 3, under about the same
conditions, and rs per cent of the wee
wills succumbed.-
rest No. a: In test No. q mix
ture OF five gallons Of molasses, five
gallons Of water and seven and a half
pounds Of calcium arsenate was used
on five hills, Twenty weevils we're
placed on the five hills. At a. M. on
the 18th, no living and for.
lis were found. On the 14th, a shower
having fallen during the night Of the
18th, another search for weeyils was
made and three additional dead and no
live ones were found.
The results of these ewDcriments
seem to show that where q LIQUID con
tanning at least half molasses and at
least thrce-fourts Of pound of cal
c1um arsenate per gallon is used, 100
per cent mortality OCCURS within
four days
The fact that a good many Of the
/ wcevils placed on the plants were un
accounted for does not modify tho
value OF the experiment as our cx-
perimenters observed some weevils to
1y away Immediately on being placed
(, on plant.
! The cotton SUI: ;lnding these cx-
periments had not been treated with
poison OF a"y kind.
| | have two letters from G. M Nor
us Of Vance, Orangeburg county, who
last year applied on or about June
!" = mixture OF one and one-half
i'~"lsis calcium arsenate and one
Qna!t OF hct water mixed with one gal
ION of molasscs. He stirred the water
nd arSeNate for 80 minutes before mix
ing with the mclasses and apDlic;l witn
mop. lic says one man or boy can
2Dply to four acres per day. fIc gath
cred 500 pounds OF Aaa, cotton per
acre and cnly made 200 to 100 round,
per acre on the balance OF tile farm.
llc does not consider this test positive
~ conclusive, owing to tho fact that
Ec had no untreated cotton in the field
with trcatcd cotton. He is confident
that the poison was responsible for his
comparative success in a section which
was almost wiped out by the wceyils
lest year. The cost Of the mixture. Mr..
Norris says, was 20 to 25 cents per
acre.
M the farmers who have reported
on tho use Of the mixture in this sec
tlon asreo that the cost is between
10 ana 20 cents for materials. Mr.. |
Norris reports that most of the farm |
ers IN his section are using tho mo-
las%cs-calcium arsenatc mixture this |
year, and SO far as lie has heard they
are pleased with the results
can not he certain that by the use |
of calcium arsenate molasses treat
mont any farmer will make crop
cS cotton and / can only be sure that
under the weather conditions we have
h2d here since May so that the vast |
majority Of the weevils have been kill
and that few weevils are left in the
treated fields and few punctured
squares are appearing. The cost of
tbe application is SO slight and the
result appears so manifest that feel |
that every farmer can i'll afford not to
invest 20 cents per acre per applica-
tion for this treatment and apply it
several times, at intervals OF week
Or ten days. There is not the slight
ost question that millions OF weevils
have already been killed by this treat
ment during the past ten days, and it
stands to reason that this has done
somo good.
