A fungal disease (Tilletia indica) of wheat and triticale that partially replaces infected kernels with a dark, fishy smelling fungal mass, first described near Karnal, India in 1931. It causes only modest yield loss directly, but because infected grain is unmarketable and the disease is subject to strict quarantine in many importing countries, its detection in a region can trigger significant trade restrictions.

Wikimedia FoundationOpening definition paragraph
Karnal bunt is a fungal disease of wheat, durum wheat, and triticale. The smut fungus Tilletia indica, a basidiomycete, invades the kernels and obtains nutrients from the endosperm, leaving behind waste products with a disagreeable odor that makes bunted kernels too unpalatable for use in flour or pasta.
