FROM the time when tobacco was first cultivated 

 in the dark-tobacco regions of Tennessee and 

 Kentucky it has been necessary to combat the horn- 

 worms in order to produce profitable crops. For 

 many years the practice of removing them from the 

 plants by hand was followed. Later Paris green came 

 into general use. This bulletin deals with the use of 

 powdered arsenate of lead, which has been found to 

 be preferable to Paris green in many respects. Full 

 directions for its use under varying conditions are 

 given.
