High Quality Content by WIKIPEDIA articles! Crown Rot of Wheat is caused by the fungal pathogen Fusarium pseudograminearum . F. pseudograminearum is a member of the fungal phylum Ascomycota and is also known as Gibberella coronicola (teleomorph). It is a monoecious fungus, being that it does not require another host other than wheat to complete its life cycle. Although F. pseudograminearum can produce both anamorphic and teleomorphic states, the teleomorph is usually not present for Crown Rot of Wheat. This Fusarium species has, until recently, been considered to be the same as the species known as F. graminearum (Head Blight of Wheat) due to many similar characteristics. One of the only differences between the two species would be that F. pseudograminearum lacks the presence of its sexual stage on the wheat host.
