THE CABBAGE WORM


Experiments With Different Remedies for
This Destructive Pest ia So
The last annual report of the Ohio
Agricultural Experiment Station con-
tains the following record of expert
ments with various proposed remedies
for this pest: I't = 81 ST n
Experiments 1-5.--Dry bran,s salt
(both coarse and fine), lime, sulphur
and white hellebore were thoroughly
applied at different times and under
various conditions. None of them
proved effective.
Experiment Cone ponnd of whale
oil soap boiled in one gallon of later
and diluted with three times its bulk Of
water, was applied with a spray pump.
Several applications were made. Many
of the worms were killed, but enough
remained to seriously injure the crop.
This remedy, although safe, can not be-
recommended as a specific. Preparing
the solution some time before using and
allowing it to become more Or less
putrid increases its efficiency.
Experiment z. - Ice water was
thoroughly tested. 1t was applied at
different times, but as rule did little
or no good When applied during the
hottest portion of the day it dislodged
some of the worms that happened to
be on the outer leaves, but failed to
have any lasting effect upon those more
in the center of the plant. Worms
were seen to rapidly recover after being
completely immersed for several sec-Y
onds in ice water.
Experiment 8.-One-half ounce ioi
pyrethrum to fifteen quarts of water,
applied with spray pump, having a
cyclone nozzle, proved an almostper-a
feet remedy, Only, one application
was made. Although a few worms APP
peared subsequently, they were not in
sufficient number to do any special IN
jury.
Experiment. 10.-Used in the form OF
powder, with o small bellows. one
ounce of pyrethrum proved sufficient
for one hundred and fifty cabbages
Twelve hours after the application was
made, careful examination showed
that no live worms could be found
No further application was found nee
essary.
Experiment 11.-One ounce of pyre-
thrum and one ounce of fine air-slacked
lime were. thoroughly mixed. This
mixture was applied in the same man
ner and same quantity as noted in, Ex-a
pertinent 10. The results were equally
satisfactory and the application less ez'

rethrum with four ounces of buck

made and applied with the Woodasor
bellows. The work was done very
rapidly, one man being able to thor.

acres of cabbages per day. This was
the most practical remedy tried, being

parts of fine Stacked lime, was nearly
as effective as pyrethrum. This was

it proved effectual, the danger OF using
