famine due to plant diseases
The Great Famine or the Great Hunger, was a time in Ireland between 1845 and 1849 of mass deprivation, illness, and movement. It was the most severely affected regions in the west and south of Ireland.
The crop collapses were produced by late disease, a sickness that damages both the leaves and the culinary roots, or tubers, of the vegetable plant particularly potato. The causative factor of late disease is the liquid mold Phytophthora infestans. The Irish hunger was critical to occur in Europe in the 19th century.
