Stem rust

Stem rust, also called cereal rust, black rust, red rust or red dust, is a fungal disease of cereal crops caused by the fungus Puccinia graminis. It damages bread wheat, durum wheat, barley and triticale, and has affected cereal farming throughout history. The annual recurrence of wheat stem rust in the North Indian plains was first traced by K. C. Mehta. Since the 1950s, wheat varieties bred for resistance to stem rust have become available, and fungicides effective against the disease also exist.
