SOME COTTON ' DISEASES * '' 



The Cotton Boll-Worm. Perhaps the earliest 

 insect to do serious damage to the cotton crop 

 was the boll-worm. It also attacks the corn 

 and tomato plant. It is known in corn as 

 the common ear-worm, getting its name from 

 the fact that the moth, laying the eggs, deposits 

 them on the silk of the young ear of the corn. 

 Here they hatch out and go into the ear and 

 feed on the tip end grains as they reach the 

 roasting ear stage. 



The cotton boll- worm is a large green to dark 

 brown worm that destroys the partially grown 

 cotton bolls by eating into them. 



They will invariably attack corn if in reach 

 before going to cotton. The best way to 

 combat this enemy in the cotton plant is to 

 use corn as a catch crop for them. When 

 corn is used for a catch crop, several plantings 

 should be made so that it will give the worm 

 something to feed on continually, without 

 resorting to the cotton patch. This may be done 

 by planting a few rows of corn around the 

 cotton patch, or if preferred, two or three rows 

 may be planted at intervals through the fields. 

 Some good may be done by the use of poison. 

 For poison to be effective it should be applied
