The scientific name of potato blackleg pathogen is Erwinia carotovora.
Blackleg is a plant disease of potatoes caused by pectolytic bacteria that can result in stunting, wilting, chlorosis of leaves, necrosis of several tissues, a decline in yield, and at times the death of the potato plant.
Blackleg in potatoes is most commonly caused by Pectobacterium atrosepticum (older synonym: Erwinia carotovora subsp. astroseptica), a gram-negative, nonsporulating, facultative anaerobe that is also associated with soft rot of potatoes.
