Wheat kernels that produce vomitoxin are infected with which disease?

Vomitoxin, also known as Deoxynivalenol (DON), is a mycotoxin produced by certain fungi, particularly members of the Fusarium genus. The disease that is primarily associated with the production of this toxin in wheat is Fusarium head blight.

Fusarium head blight primarily affects the heads of wheat plants and is caused by the Fusarium graminearum species. When the fungus infects the wheat kernels, it can lead to the production of vomitoxin, which can have significant implications for grain quality and human health, as it can contaminate flour and other wheat products.

Wheat scab, another name for Fusarium head blight, denotes both the disease and the condition of the crop leading to diminished yield and quality. Because of the direct correlation between this disease and vomitoxin production, identifying and managing Fusarium head blight is crucial for maintaining healthy wheat crops and safe food supplies. The other diseases listed, such as leaf spot and rust, are not associated with vomitoxin production, making them less relevant in the context of this question.
