In 1883 late blight of potato was advertently introduced in India from Europe.
Irish famine also known as the Great Irish famine, occurred in Ireland in 1845 - 49 when the potato crop failed in successive years.
The crop failures were caused by late blight, a disease that destroys both the leaves and the edible roots, or tubers, of the potato plant. The causative agent of late blight is the water mold Phytophthora infestans.
