Phytophthora infestans is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight , caused by Alternaria solani , is also often called "potato blight".
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]
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 ...

This variety is a mutation (or sport) of the cultivar 'Burbank's Seedling' that was selected by the plant breeder Luther Burbank in 1873. The known lineage of Russet Burbank began in 1853 when Chauncey E. Goodrich imported the Rough Purple Chili from South America in an attempt to add diversity to American potato stocks which were susceptible to late blight.
