DITHANE SPRAY OR DUST PROGRAM 
BEGIN applications when plants are 2 to 4 inches high. 
For first spraying—use 50 to 75 gallons of spray per acre. 
For first dusting—use 20 to 25 pounds of dust per acre. 
REPEAT applications at weekly intervals. During periods of cool, wet weather, favorable to the development of late 
blight, spray or dust at 3 to 5 day intervals. 
Increase spray gallonage as plants become larger—125 to 175 gallons per acre may be required to cover mature 
vines. Adjust nozzles to insure maximum coverage. Maintain pressure of from 375 to 450 pounds. 
Increase dust dosage as plants grow. Use 40 to 50 pounds per acre on mature vines. Direct nozzles to get thorough 
coverage of new and older vine growth. 
CONTINUE regular sprays or dusts until the vines are dead from maturity or frost. If earlier digging is desired, kill tops 
with a vine killer (chemical or mechanical) and wait from 7 to 10 days to begin digging. This will give the potato 
skins a chance to set and there will be less tendency to bruising and scuffing during digging. 
. DIG, HANDLE AND STORE= WITH CARE 
Potatoes are relatively tender and damage easily if given rough treatment during harvesting and subsequent handling. 
You can minimize waste and unnecessary loss by adjusting and padding your digger to reduce bruising and by careful 
loading and unloading of field trucks. 
Potatoes like cool, damp storage conditions. Prompt cooling of the storage house after filling helps to reduce weight 
loss and prolong dormancy.
