For many potato producers, late blight is a well-known disease – either because they're unfortunate enough to have already experienced it, or they're from a region that has had highly publicized late blight symptoms observed. Late blight requires a fairly specific combination of climate and other external factors.

Potato Board, shares the conditions that result in late blight, what to look for and how to work with agronomists and local labs to learn more about late blight.
