Trichothecenes

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. The occurrence of deoxynivalenol is associated primarily with Fusarium graminearum (Gibberella zeae) and F. culmorum, both of which are important plant pathogens which cause fusarium head blight in wheat and gibberella or fusarium ear blight in corn. The incidence of fusarium head blight is strongly associated with moisture at the time of flowering (anthesis),

class=skin-invert-image|thumb|right|180px|Chemical structure of the trichothecene core Trichothecenes constitute a large group of chemically related mycotoxins. They are produced by fungi of the genera Fusarium, Myrothecium, Trichoderma, Podostroma, Trichothecium, Cephalosporium, '' and Stachybotrys''. Chemically, trichothecenes are a class of sesquiterpenes.

Satratoxin-H, a trichothecene mycotoxin, is a naturally occurring toxin produced by the ascomycetes Stachybotrys chartarum and Trichoderma cornu-damae which is highly toxic and potentially fatal to humans and other animals. The clinical condition it causes is known as Stachybotrotoxicosis. It is related to the mycotoxin T-2, but unlike T-2 has not been reported to have been used as a chemical weapon.

Trichodermin is a trichothecene. It inhibits protein formation in Euchariotes.

Diacetoxyscirpenol (DAS), also called anguidine, is a mycotoxin from the group of type A trichothecenes. It is a secondary metabolite product of fungi of the genus Fusarium and may cause toxicosis in farm animals. The US Health and Human Services agency considers it a select agent for research purposes.
