POTATO SCAB. This wide.spread disease affecting Potato tubers is due to the attack 

 of a parasitic fungus, which causes the skin to become rough and scabby. This disease 

 may be successfully combated by treating the planting stock with German Formalin or 

 the American brand called Formaldehyde; 8 fluid ounces (I pint) of this antiseptic is to be 

 used in 15 gallons of water, which is sufficient to treat 20 to 25 bushels. The Potatoes should 

 be freed from dirt by washing if necessary, then soaked for 1 V2 hours in the dilute solution, 

 after which they are to be dried, cut and planted in the usual way; care being taken that 

 the treated Potatoes do not again become infected by contact with contaminated sacks or 

 other receptacles.
