DistributionWorldwide, where corn is grown[2][3]

Corn smut is a disease that affects corn, which is also called maize. The fungus Ustilago maydis causes corn smut.

Lumps of growing tissue called galls grow on the corn. They can grow on the ears, leaves or stalks. Corn is more likely to have corn smut if it has been cut by machines or hailstones.

Farmers can stop corn smut by using corn that has been bred to be strong against the fungus. Farmers can also stop corn smut by crop rotation. This is because the fungus can wait in the soil over the winter for the next crop. If the corn is not in the same field each year, it is harder for corn smut to reach new corn plants.[4]

Corn smut is safe to eat, and chefs cook it.[5]
