THE COTTON WORM OE COTTON CATEEPILLAK. 



The work of poisoning the insect should be undertaken as soon as 

 injury becomes apparent in any portions of the fields. By this means 

 the expense of control will be greatly reduced. 



In regions where the boll weevil is abundant the planter should 

 take care not to poison the caterpillar too early. If he does so the 

 production will certainly be reduced. Where the weevil occurs in 

 considerable numbers no poisoning for the caterpillar should be done, 

 unless there is considerable ragging of the leaves before the earhest 

 boUs are three-fourths grown.
