What is vomitoxin in wheat?
Deoxynivalenol (DON), commonly referred to as vomitoxin, is a mycotoxin that may be produced in wheat and barley grain infected by Fusarium head blight (FHB) or scab. FHB may infect grain heads when wet weather occurs during the flowering and grain filling stages of plant development.
What crops are eligible for crop insurance?

Losses must be due to things which are unavoidable or beyond the insured’s control such as drought, freeze and disease.
Where is vomitoxin found?
Vomitoxin, also known as deoxynivalenol (DON), is a type B trichothecene, an epoxy-sesquiterpenoid. This mycotoxin occurs predominantly in grains such as wheat, barley, oats, rye, and corn, and less often in rice, sorghum, and triticale.
Why is it called vomitoxin?
From samples of infected corn they ground, extracted, separated and identified the culprit. They named it vomitoxin, because it caused pigs to, you know, vomit.

What fungus produces vomitoxin?
Deoxynivalenol (also known as vomitoxin or VOM) is a mycotoxin produced by the fungus Fusarium graminearum, which causes Fusarium head blight (FHB), or scab, of small grains. DON can cause feed refusal in livestock and vomiting in humans and animals.
