Karnal bunt is a fungal disease that affects the kernel of wheat and triticale. Climatic conditions play an important role in appearance of the disease. It occurs only when weather is cool and wet at the time wheat is flowering. Infection spreads primarily through infected seed. In India, where Karnal bunt was first discovered, infected seed is planted throughout the country, but the disease occurs only in locations with a suitable climate. In the United States, Karnal bunt has been found in parts of California, Arizona, New Mexico, and Texas.
The disease can be managed by using clean seed. Karnal bunt does not cause significant yield loss. However, its appearance in wheat has serious economic consequences for exporters.
