Alternaria solani is a fungal pathogen that produces a disease in tomato and potato plants called early blight. The pathogen produces distinctive "bullseye" patterned leaf spots and can also cause stem lesions and fruit rot on tomato and tuber blight on potato. Despite the name "early", foliar symptoms usually occur on older leaves. [3]
Early blight, caused by Alternaria solani, is also often called "potato blight". Late blight was a major culprit in the 1840s European, the 1845–1852 Irish, and the 1846 Highland potato famines. The organism can also infect some other members of the Solanaceae.

The European potato failure was a food crisis caused by potato blight that struck Northern and Western Europe in the mid-1840s. The time is also known as the Hungry Forties . While the crisis produced excess mortality and suffering across the affected areas, particularly affected were the Scottish Highlands , with the Highland Potato Famine and ...
In the early 1800s, a strain of potato blight (Phytophthora infestans) known as HERB-1 began to spread in the Americas, especially Central and North America, destroying many crops. The blight spread to Europe in the 1840s where, because of an extreme lack of genetic diversity, the potato crops were even more susceptible. In Northern Europe ...

The Highland Potato Famine (Scottish Gaelic: Gaiseadh a' bhuntàta) was a period of 19th-century Highland and Scottish history (1846 to roughly 1856) over which the agricultural communities of the Hebrides and the western Scottish Highlands (Gàidhealtachd) saw their potato crop (upon which they had become over-reliant) repeatedly devastated by potato blight.
