One of the most well-known diseases caused by Ceratocystis paradoxa is Black rot or stem-end rot of pineapple, but it can also infect tropical fruit plants such as banana and coconuts as well as sugarcane. The pathogen infects the fruits through wounds or other openings after harvest has already happened and the fruit is fresh.
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 ]
Other diseases include citrus pink disease, bacterial heart rot, anthracnose, [83] fungal heart rot, root rot, black rot, butt rot, fruitlet core rot, and yellow spot virus. [84] Pineapple pink disease (not citrus pink disease) is characterized by the fruit developing a brownish to black discoloration when heated during the canning process.
Fruitlet core rot (FCR) is the disease of a pineapple fruit, from the pathogen Penicillium funiculosum that is brown or black in color and rotted in the center. [2] FCR is associated with multiple pathogens, such as Candida guilliermondi in addition to P. funiculosum, however, leathery pocket (LP) and interfruitlet corking (IFC) are only associated with P. funiculosum.

Other species damage sugarcane, grapes, pineapple (Jahn et al. 2003), coffee trees, cassava, ferns, cacti, gardenias, papaya, mulberry, sunflower and orchids. Mealybugs only tend to be serious pests in the presence of ants because the ants protect them from predators and parasites. [ 2 ]
