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.
The English, who had no use for the Irish, spread the potato blight germs around on the potato fields so that they could get rid of as many Irish as possible. It largely worked - millions of Irish either starved to death or immigrated to other nations, like Canada and the USA. (That's why my greatgreatgreatgreatgreat grandfather came to America)
The Irish were farmers and relied heavily on potatoes as a food source; when the potato blight struck Ireland people starved.
There was a disease going around called mildew which made the potatoes all black and mushy so nobody could eat them or they would be poisoned The disease was not called Mildew, it was called The Blight (Phytophthora infestans). The potato famine was caused by a fungi called potato blight. after just days from coming out of the ground, the potato's would be slimy, black, and rotten.
"Back then" could refer to any time. If you are referring to the famine times in the second half of the 1840s, the potato was the main element of the diet and its destruction by blight caused the famine. Poor people would not have been able to get much meat or other more nutritious foods and relied on the potato. In modern day Ireland, a wide range of foods are available with Irish cuisine and foods from many other countries all available.
Some potatoes would be more likely to have a genetic resistance to the disease and survive. (Study Island)
Famine could lead to starvation and death. So, if there are no foodstuffs in storage, people will move to an area where food is still available. When wet weather and the potato blight over several seasons caused starvation to many people in Ireland, many Irish emigrated to America.
It is still an important crop and used in many ways for meals, but it could not be said that Ireland is now dependent on it.
The disease blight started in 1845 in Derry witch spread and spread until the whole of Ireland was covered!The Blight was a disease that posioned Potatoes and Potatoes were the only food Irish people could grow in bad ground or bad weather conditions! Many people went to work house!
The blight on the crops devastated the village.His house is a blight against the landscape.
