Smuts and bunts are Monocyclic.
Bunt, also called stinking smut, fungal disease of wheat, rye, and other grasses. Infection by Tilletia tritici causes normal kernels to be replaced by “smut balls” containing powdery masses of brownish black spores characterized by a dead-fish odour.
Bunt and smut fungi can cause the most devastating disease of cereals. The zero or very low tolerance levels at receive centres can make diseased grain only saleable as low value stock feed.
Fortunately, the regular use of seed applied fungicides (pickles) can cheaply and effectively control these diseases.
