Protect THE GRAIN FROM
WEEVIL

Whist Il generally known to the farmer
- ~weevfl." Not only Is the actual
feeding value lost in infected grain,
but the presence of weevil, especially
n wheat, regardless Of how little the
1amngs, always cuts the grade one or
Two points.
And now that tho heavy rains OF the
summer have caused much wheat to
sprout in the shock, or mold where 1t
was hauled into the barn too wet or
green, the determination Of the weevi1
IL one other precaution that must
needs be taken to conserve the small
amount thus saved. Weevily wheat Is
not good feed, It is not good for -four.
and II Isn't good for seed.
In the work OF controlling granary
pests Prot. e. N. Cory, Of the Ento-
mology department Of the State AgE-
cultural College has issued a circular
In which the Carbon Bisulphide
Method Of control is thoroughly e1.
planned.
Tue term "weevil." as used, Is a
general name for large number OF
insect pests that attack stored grain
products. But It is probably the
Angoumois moth that does the great
ct damage, often working through IS
much as 80 per cent of the grain IN
tho bin. The eggs of this fawn col
ored moth are deposited in masses be-
tween the kernels of corn or wheat
IN the shock or in the granary and
the larvae or worms Matching there
from enter the grain and feed within.
When ready to pupate, they cut their
way to the outside shell leaving only
the outside membrane over the exit
hole. The moth, when it energies from
he pupa case, easily breaks this
membrane and energies from the
grain to produce another genera
ton Of insects. If conditions are favor
able many generations are produced In
. year.
Fumloation with Carbon Bfsuiphlde
has proved the most effective method
Of control.
Carbon Bisulphide or Disulphide is
Z sdyhtly yellowish liquid having q
very disagreeable odor (about the
same as that OF rotten egg) due to
impurities. It Is highly volatile, that
q, evaporates quickly, and produces q
gas heavier than air and very infann-
mable.
How To Use Carbon BisuIphlde.
Carbon Bfsulphide should be used at
the rate Of to 8 pounds per 1000
cubic feet of space in the granary or
Per every 100 bushels Of grain to be
fumigated. The outside temperature
should be about 70 degrees at the time
Of fumigation for best results.
II the grain Is in room that Is
capable OF being closed tightly, the
liquid may be exposed In shallow pans
above the grain, on saturated pieces
of burlap or It can be poured into the
pile through piece OF pipe.
II . tight room is not available the
grain may be covered with a tarpaulin
or q piece of canvass and the Carbon
Bdsulphide exposed beneath it.
The greatest care should be used In
regard to fire. Never carry Lighted
lantern, pipe or cigar into a barn
where Carbon Bisulphids fumigation
= In progress.
Tho exposure should last for IS
hours. The funigation should be re-
psatsd after an interval Of two weeks.
Shovel the grain over after each
fumigation 50 as to air It and prevent
The collection of moisture and possible
subsequent heating.
Where directions are followed there
= no chance for human poisoning az
The Carbon Bisulphide evaporates COM
pletely.
Carbon BisuIphide can be purchased
from almost any drug store in small
quantities or from any chemical sup
My house. In large amounts 1t may
be secured from E. r. Taylor, Penn
Yam. N. T., or the Independent Chemi'
cal Company, u Front street, New
York City.
