Background
Karnal
bunt is a fungal disease of wheat and triticale (a hybrid of wheat and
rye). The disease is caused by the fungus Tilletia indica Mitra,
also known as Neovossia indica. Typically, only a portion of
the wheat kernel is affected; this is why the disease is sometimes called
partial bunt. This disease is influenced by weather and climatic conditions
- the most severe infections occur when there is cool and wet weather
at the time the wheat is heading out. The disease was discovered in
1931 in the city of Karnal in northern India. The disease has been found
in Pakistan, Afghanistan, Iran, Mexico (since the early 1980's), Nepal,
Syria, and a few places in the United States.
