SOME COTTON DISEASES IIJ 



the adult weevils will collect in the windrows 

 or piles and be destroyed when the stalks are 

 burned. 



Another plan practised is to turn cattle in 

 the fields to eat the foliage and immature bolls. 

 This plan, however, should not be followed 

 except by those farmers who can turn in 

 enough cattle to completely clean up the 

 field in a week's time. 



The object in destroying the stalks is a 

 twofold one: (i) To deprive the adult weevil 

 of food and breeding places; (2) to kill the 

 vast numbers of weevil eggs, larvae, and pupae 

 contained in the squares and immature bolls 

 at this time. To make this destruction com- 

 plete, the stalks should be burned as soon as 

 possible after being cut and piled. As soon 

 as the foliage will burn readily fire should be 

 applied, although the main stem and branches 

 may not yet be dry enough to burn. All 

 rubbish in and about the field should also be 

 burned and the field immediately broken. 



If this single instruction to destroy all cotton 

 stalks in the fall while still green could be 

 carried out by every grower, it would practically 

 solve the weevil problem. The difficulty is
