Monilinia oxycocci (Woronin) Honey, (synonym Sclerotinia oxycocci), common names cranberry cottonball, cranberry hard rot, tip blight, is a fungal infection of large cranberry (Vaccinium macrocarpon) and small cranberry (Vaccinium oxycoccos).[1] The tips of young flowering shoots wilt before they flower. Fruit that forms on the plant can then be infected by the asexual spores[2] traveling through the plant, causing the berries to harden, turn cottony on the inside, and dry out instead of maturing.[3] The berries are filled with a cotton-like fungus and are generally yellowish with tan stripes or blotches at maturity, making them unmarketable.[4] It results in important economic impacts on many cranberry marshes, particularly in Wisconsin.
