 disease occurs, all wilting vines should be removed and 

 destroyed at once and the tubers^ if stored, should be 

 kept cool and dry. The chief remedial measure con- 

 sists in thorough spraying with arsenites, or Bordeaux 

 mixture and arsenites, to keep the vines free from the 

 insects which carry the germs.
