Seed Treatment
Disease

Treatment
Scab ...... Soak uncut seed in formalin, I

pound to 30 gallons of water, for two hours; then dry and plant on

scab-free soil. Rosette (Rhizoctonia) . As for scab. Dry Rot. . . . . . Diseased tubers to be destroyed;

those in contact with them to be treated as for scab and sprayed

as for blight. Wet Rot (due to Blight or Bacteria) . . . . Have seed potatoes in such storage

that they can be examined, and these tubers sorted out and destroyed. Do not plant affected tubers. Soaking them in formalin, as for scab, is advisable in some cases, depending on the

cause. Stem Rotor Dry End

Rot (Fusarium oxysporum). ...It attacks the stem-end first; hence,

cutting off this end of suspected tubers will reveal the disease. Discard diseased tubers.
