The symptoms of souring become noticeable only when the fruit ripens and the eye opens.
Infected figs develop a pink color and later become water soaked.
In later stages the pulp disintegrates and usually is covered by a white scum. The affected figs turn soft and black, sag, shrivel, dry up, and either drop or hang on the twig until harvest. A dead spot or eye canker often develops in the bark around the attachment of the stem of the fruit. No chemical controls are suggested. The Regents of the University of California.
