Pineapple black rot, also known as butt rot, base rot, or white blister, is a disease caused by Ceratocystis paradoxa (teleomorph) (Thielaviopsis paradoxa: [1] anamorph). C. paradoxa also causes disease in a variety of other tropical plants such as banana, coconut, and sugarcane making it a somewhat dangerous pathogen. [2]
If the pathogen infects the plant while fruits are still on it, they will prematurely drop. Other symptoms include discoloration of leaves as well as the seeds. The lesions on the fruit evolve to become soft rot spots that produce a heinous odor. The fruit can even get to the point of breakdown. [3] Known hosts: Ananas comosus (pineapple) Araceae

As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. Powdery mildew grows well in environments with high humidity and moderate temperatures; greenhouses provide an ideal moist, temperate environment for the spread of the disease.
