The major route of entry of the smut fungus (Ustilago scitaminea Sydow) is through the bud (Fawcett, 1944; Bock, 1964; Waller, 1970). Young buds are very susceptible to infection with resistance increasing with bud age (Bock, 1964; Byther and Steiner, 1974). Before infection occurs the spores must germinate on the bud surface.
