Farmers can do several things to prevent vomitoxin from getting into food. They can use crop rotation, plant seeds that have been checked to have no "Fusarium" in them, plant types of crops that are strong against "Fusarium", and put fungicide on the crops to kill the fungus. Because fungal infections make the crop plants smaller and lighter, sometimes farmers can use combine harvesters to blow air on the crops so that the infected wheat blows away leaving the heavier healthy wheat behind.
