There are two diseases of potatoes that are commonly called blight: late blight and early blight. The following articles will help you identify them and will give you information on treatment.

If you determine that your potatoes had one of these diseases, the best option for next year is to rotate crops- plant something that's not in the nightshade (Solanaceae) plant family and that therefore won't be susceptible to the same diseases:
