THE FALL ARMY WORM.
Clemson Bureau OF Entomology Tells
How to Exterminate Pest,

Clemson College, July 26.-Spe-
cial: There is in this State and seve-
raj other Southern States an inva-
sion of the fall army wor.n on corn,
grass and cotton. This caterpillar
Is about one to one and a half inches
long when grown. 1t Is quite diff
ferent from the cotton caterpillar,
although many farmers mistake one
for the other. This insect which is
now in this State Is not the cotton
caterpillar which did so much in
jury to cotton last summer, but Is
the fall army worm, which Is some-
times called the grass worm.
The fall army worm Is usually
present, but in such small numbers
that they do no harm to the crops,
but on the other hand eat the grass
in the fields. 1t is only when this
insect gets abundant that it does
harm by eating grass, corn, peas
and cotton. The weather conditions
this season have been unusually fa-
vorable for it's development. Most
farmers who have seen the work Of
this insect realize that immediate
action is necessary for the control Of
this pest.
Control Measures.
The two poisons that have given
the best satisfaction so far are pow
dered arsenate Of lead and Paris
green. Paris green can usually be
bought at a local drug store, while
as Il rule arsenate OF lead is not han
died by such dealers. The arsenate
OF lead can be secured from whole
sale dealers and most all seed houses
A few such firms are Lamar-Rankin
Of Atlanta, Willett Seed Co., Angus
ta, w. NJ. Bird & Co., Charleston
Murray Drug Co., Columbia, p. J.
Burkmans, Augusta, Sherwin-Wil-
liams Co., Savannah
How to Distribute Poison.
About six inches from each end
of board one inch thick and four
inches wide, and twelve inches Ion
ger than the width of the rows, bore
a hole one inch or more in diameter.
Cut two pieces Of cloth 20 by Ia
inches, the cloth being about the
weight Of S-ounce duck. Make two
bags of these pieces of cloth and
tack one on each end, securely un-
der the hole in the board. The
holes in the boards may be closed
with wooden shoppers made for that
purpose. The bags are about five
inches deep and fifteen inches long.
This arrangement can be carried on
foot or on mule and two rows
treated at the same time. Apply in
the morning while the dew is on the
plants, but do not get the bags wet.
If Paris green is used repeat If rain
washes it off.
Amount OF Poison to Use.
For cotton three feet high use the
following amounts OF which ever
poison is used. The amount varies
according to whether the cotton is
smaller or larger than three feet
high. In the case OF corn and other
plants vary accordingly.
Arscnate Of Lead: Four to five
pounds per acre. No danger Of
burning.
Paris Green: Two to two and a
half pounds per acre. On large
plantations, where quick work is i'm
perative, the Paris green should not
be used in quantities materially eX-
ceeding the dose given above. as
there Is danger Of seriously burning
the foliage.
The second generation will likely
appear in about three or four weeks
after the present generation disap-
pears and will possibly be more
numerous. 1t will be we'll to keep
on the lookout for the second out
break.

ccrning this or any other insects.
