The most destructive fungal spoilage agent of apples and pears is Pen. expansum, which causes a blue rot. Damaged and over mature fruits are the most susceptible. Core rot in apples, is the growth of any variety of molds initially in the seed cavity and then spreading to the mesocarp tissue. Molds that have been associated commonly with this type of spoilage are Alt. alternata, Botrytis cinerea, Penicillium spp., Coniothyrium spp., Pleospora herbarum, and Pestalotia laurocerasi (Combrink et al., 1985). Botrytis cinerea causes grey rot in cold-stored pears and, less commonly in apples (Hall and Scott, 1977). The rot is firmer than blue mould rot, and becomes covered in ash–grey spore masses.
