Never use white arsenic on plants, it will burn them. 
(6) An immense amount of good can be accomplished in destroy- 
ing these worms by the use of a poisoned bait which is scattered 
broadcast over the infested fields. Take 50 pounds of bran and mix 
with it either 1 pound of Paris green or 2 pounds of lead arsenate, 
then add 2 gallons of low-grade molasses and 6 finely chopped lemons. 
This is especially recommended for fields containing mixtures of 
grass and cowpeas, cowpeas and sorghum, or fields in which grass 
has been consumed by the caterpillars. 
Caution: Do not pasture stock in fields where the grass or other 
crops have been sprayed with a poison mixture until after heavy 
rains have fallen and not before three weeks after the application of 
the insecticides.
