Puccinia graminis

Category:

Plant pathogen

Etymology:

Genus name: Possibly named after the Italian opera composer Gioacomo Puccini.
Species epithet: from grass.

Common name:

Cereal, black or stem rust

Significance:

Stem rust is today considered to be the most serious rust disease globally and infestation can cause large crop losses. Significance has declined in recent years, however, as resistant cereals have been developed.
[Important]

Geographic distribution:

Stem rust occurs all over the world.
