established around newly discovered 

 infestations. All material on which 

 the weevil feeds is removed from 

 these zones in an effort to starve the 



weevil. Dieldrin or aldrin is used 

 to kill weevils in this zone before 

 the materials on which they feed 

 are removed. 



Precautions 



Insecticides are poisonous. Handle them 

 with care. Follow the directions and heed 

 all precautions on the container label. 



Dieldrin and heptachlor can be absorbed 

 through the skin. After working with these 

 materials, wash all exposed surfaces of the 

 body with soap and water. Put on clean 

 clothing. 



Vines treated with dieldrin or heptachlor 

 should not be fed to dairy animals or 

 animals being finished for slaughter. 



If you apply DDT to harvested sweetpota- 

 toes, remove the excess residue by thor- 

 oughly washing them before they are sold 

 or eaten. Do not feed DDT-treated pota- 

 toes to dairy animals or animals being 

 finished for slaughter. 



Store insecticides in a dry place out of 

 reach of children and animals.
