English

Subject field(s)
  • Fungi and Myxomycetes
  • Plant Diseases
CONT

Smuts, of the fungus order Ustilaginales, are named for their sooty black spore masses. Like the rusts, they belong to the Basidiomycetes and are all plant parasites, of most economic importance on cereals and grasses, but they differ from rusts in having a less complicated life history and in being able to live part of their lives saprophytically in rich organic matter or in culture media.

CONT

There are three types of infection with smuts ... 1. Infection of seedlings as the seed germinates, from spores adhering to the outside of the seed or present in soil ... 2. Seedling infection by mycelium within the seed as a result of ovary infection from spores germinating on the stigma ... 3. Infection of any actively growing meristematic tissue (roots, shoot, tassels, or young ears) by spores transported by wind from decaying plant material ...
