Show Treat Potatoes Before Planting Solution of Corrosive Sublimate Sublimate mate or Formaldehyde e eIs Is Effective Experiments have shown that potatoes pota pots toes can con be treated for disease control In the winter while they are dormant with no delay In germination In the spring according to C.
