. Fig. 15.—Blossom-blight phase of apricot bvoAvn rot. Blossom-End Rot, Internal Rot, Alternaria Rot.—Blossom-end rot is characterized by a firm, black rot, beginning at the blossom end and progressing internally around the pit, which becomes surrounded with a black mold and spores of a species of Alternaria. Some injury prob- ably precedes this. There is no apparent way in which this trouble can be controlled, but it is not of very common occurrence.
