ETCH, which has become an important forage 
crop throughout the Southeastern States, needs 
protection from the same insect that works such 
havoe on corn and cotton. This corn earworm, or 
cotton bollworm, is the most serious pest that 
growers of vetch have to combat. The caterpillars 
eat both the foliage and the seed pods, and, if 
the infestation is heavy, make the crop practically 
worthless. 
Vetch intended for a hay crop generally escapes 
serious injury, as it is cut before the caterpillars 
are large enough to do much damage. It is recom- 
mended that a crop intended for seed be carefully 
watched and if the insects become numerous an in- 
secticide be applied at once or the vetch cut for hay. 
Spraying, dusting, the use of poisoned-bran bait, 
and other control measures are discussed and sum- 
marized in this bulletin.
