The first step in controlling corn
weevils is to select the seed corn in
the field, paying Especial attention to
the ears that are we'll covered by the
shuck and if possible that hang with
the pointed end downward. This is
an important precaution, although
not sufficient to fully protect the corn
in the cribs.
Treatment of Corn in Cribs.
Carbon bisulphide is a colorless Ii
quid with strong disagreeable odor.
1t vaporizes rapidly at ordinary tenn
peratures, is highly indammable and
when ignited is explosive. 1t is,
therefore, important to keep away fire
of any kind, whether flame, stove, Ian
tern, embers, lighted pipe or cigar.
This chemical is very widely used at
present, and when the above precau-
tions are observed there are no dan
gers from accident. It may be pur-
chased at any drug store or chemical
wholesale house, ranging from ten to
twenty-five cents per round. The
brand that has given the best salts
faction in our experimental work is
named Fuma and costs about ten
cents a pound. The liquid and Vapor
coming from it are heavier than air
and will sink, therefore the applica-
ton is made at the. top of the crib
and not from below. F'umigation
should be done on warm days as vola-
tilization is slower in cold weather
and consequently less effective.
Assuming that the crib is moderate
ly tight, it is used at the rate Of three
pounds to 100 bushels of grain, or ap-
proximately 1000 cubic feet of space,
the latter being for an empty crib. 1t
should be repeated in ten days. 1t
may be distributed in several shallow
vessels, but the simplest way is to
sprinkle it over the top like water
and if blankets are available the. sur
face of the corn should be covered.
Where the bin IS open, the best pos
sible thing to do is to make it tight
In case of log cribs, this may be ac-
complished by means Of canvas tack
ed over the walls.
| Where only a small quantity Of
grain is to be fumigated, such as seed
corn or cowpeas used for seed, it fnay
be accomplished by pouring it in a
coal oil or molasses barrel. Such a
barrel will accommodate about three
bushels. Three to five ounces Of car
bon bisulphide is poured over the sur
face and the barrel tightly closed for
twenty-four to thirty-six hours. The
top Of the barrel may be made per-
fectly tight by covering it with several
/ burlap bags weighted down with
boards. A permanent covering for
this purpose may be made by heavily
painting piece of canvas Of proper
size, which is then laid over the open
ing and a barrel hoop dropped over
the tod to hold it firmly in position.
Carbon bisulphide is not poisonous
nor caustic. It drives the air from
the space to. which it is applied and
cause suffocation. When overcome
by this gas in a building, the symp-
toms consist of a dry feeling Of the
skin and a streaked headache, accom-
panied by dizziness. This will pass
off Immediately after a person reach
es the fresh air. 1t is not advisable
that people affected with heart trou-
Bile handle this gas to any great ez-
tent
among other methods for controll-
ing weevils, lime and sale are some
times recommended. These materials
are ret nearly as effective as fumiga-
ton. while the decrease in the pala-
tahI1itv of the corn, where lime is en-
ploved, makes the use Of this material
Objectionable.
The use of each does not decrease
the palatability but, in order that il
