Moldy core is associated with several different fungi. Infection is initiated at the calyx end and the fungi proceed to grow inward into the carpel tissue or locules and cause a core rot. External rot symptoms are rare. Fruits ripen early and decay is only obvious when fruit are cut in half (A, B). Core rot appears similar but occurs after harvest when the fruit are dipped into contaminated water in the packinghouse. A wet rot develops once the fruit are in storage.
