Pineapple black rot

Post-harvest disease of pineapple fruit

Pineapple black rot, also known as butt rot, base rot, or white blister, is a disease caused by Ceratocystis paradoxa (teleomorph). C. paradoxa also causes disease in a variety of other tropical plants such as banana, coconut, and sugarcane making it a somewhat dangerous pathogen. Pineapple black rot is the most common and well-known post-harvest disease of the pineapple fruit and is responsible for serious losses in the fresh pineapple fruit world industry. The pathogen is a polyphagous wound parasite and gains entry into the fruit via wounds sustained during and after harvest. The disease only shows up in fresh fruit because the time from harvest to processing it too short for infection occur. Infection can also occur out in the field, but it is not nearly as common as post-harvest infection.
