Diseases of apples in storage
1920

"Storage diseases take a heavy annual toll on the harvested crop of apples, greatly reducing an important food supply and increasing the cost and uncertainty of market operations. The responsibility for this loss may lie with the orchardist, the transportation company, the dealer, or the storage management. Delay in warm packing sheds or cars shortens the natural life of apples and greatly increases their tendency to rots and to scald. Filling the storage rooms so rapidly that cold-storage temperatures can not be maintained has a similar bad effect. Apple rots are slow to start at a temperature of 32° F., but if a beginning has been made at a higher temperature they can proceed much more rapidly. Ventilation of storage rooms is of great value in scald prevention when the air within the package can really be renewed, but this is a difficult thing to accomplish under commercial conditions. Apples scald far less when in boxes, baskets or ventilated barrels than in the usual tight barrel. Wrapping apples in oiled wrappers furnishes the most complete protection against scald."--Page 2.
