Sugarcane Pineapple Set Rot is another name of Pineapple Disease.The fungus Ceratocystis paradoxa is responsible for Pineapple disease. The disease derives its name from the scent produced by rotting seed pieces, which is similar to that of ripe pineapples.
Ceratocystis paradoxa produces several types of spores which are important in its survival and spread. Two types of asexual spores (conidia) are produced: brown, thick-walled conidia produced in chains; and hyaline (clear), thin-walled conidia, which are more short-lived. Additionally, ascospores produced by a sexual stage are produced within small, dark-brown to black, vase-like structures called perithecia. All three spore types, produced by the millions on the internal tissues of infected seed pieces, are released into the soil upon seed piece decay. There, the spores may survive for several years, serving as a source of inoculum for the next crop
Pineapple disease is essentially soilborne, being transmitted by the fungal spores present in the soil. The fungus is found mainly in the top 25 cm of the soil profile.
Any factor that delays germination of the buds on the seed piece increases the likelihood of infection. Excessively deep planting, wet or dry soil conditions, and low temperature are all conducive to the development of the disease. Long hot-water treatments used to control other diseases may have a detrimental effect on germination and thus may actually increase susceptibility to pineapple disease. Even short hot-water treatments, which usually stimulate germination, may result in increased susceptibility. In general, rapid germination decreases the impact of the disease.
Infection of standing cane occurs through wind-blown or rain-splashed spores gaining entry through damaged tissue.
