Only very few varieties of potato were brought to Europe from the New World and so the potatoes cultivated in Europe weren't sufficiently robust to offer strong resistance to diseases, since they lacked genetic diversity. The European potato was, therefore, unable to fight the potato blight, or late blight, and many crops were destroyed.
The impact was most felt in Ireland, which had become highly dependent on potatoes: the country lost about a quarter of its population.

Yes, Potato blight is endemic in Ireland and Europe, but today a variety of types of potato are grown some of which are blight resistant and we also have chemical sprays that can kill the fungus. The trouble with the blight in the past was that there were no sprays and only one variety of potato was grown and when a blight evolved to attack this variety, it meant that ALL the Irish crop was hit and this lead to famine.
It rots the potato making it unfit for eating.
