Squirter disease

Nigrospora musae

Nigrospora can cause a dark center in the banana which can eventually lead to a softening of the entire banana pulp. This fungal disease, known as Squirter's (because eventually the soft banana pulp can "squirt" out of the banana skin) is common in tropical areas where bananas are normally grown. The fungal disease develops from infection at the time the bunches are cut into single fruits and develops during transportation and ripening.  Initially, the disease can be seen as a dark core, or a broken line of dark-red gum-like substance along the center core or near the end. The fruit becomes soft, and the flesh is transformed into a mushy liquid which squirts out at the base when slight pressure is applied.
