How is Erwinia carotovora treated?
There are no compounds that can rid infected plants of Erwinia; although, bactericides containing copper can help slow the spread of the pathogen. Antibiotics have been recommended, but the bacteria adapt and populations become resistant within a matter of weeks.
How is soft rot spread?
Soft rot can be spread by infected seed, with infection in the next generation of tubers being higher as the percent infected of seed potatoes increases. Soft rot should be controlled throughout the life of a crop to reduce its impact on future generations of potatoes.
What causes Erwinia carotovora?
Soft rots are caused by several bacteria, most commonly Pectobacterium carotovorum (previously called Erwinia carotovora), Dickeya dadantii (previously called Erwinia chrysanthemi), and certain species of Pseudomonas, Bacillus and Clostridium.

Which one is a soft rot causing fungus?
Examples of soft-rot-causing fungi are Chaetomium, Ceratocystis, and Kretzschmaria deusta. Soft-rot fungi are able to colonise conditions that are too hot, cold or wet for brown or white-rot to inhabit. They can also decompose woods with high levels of compounds that are resistant to biological attack.
