| Etymology:
|
Genus name: spindle.
Species epithet: of grass. |
|---|
| Alternative Species Name(s): | Gibberella zeae, which is the name of the fungus in the teleomorphic stage. |
|---|
| Significance: | This fungus is of great economic importance due to reduced crop yields and contamination of mycotoxins.

| Disease/effect:
| | Hosts/substrate | Disease/effect | Clinical picture or result |
|---|
| Barley, maize, rice and wheat. | Fusarium head blight (FHB) which is a devastating disease on wheat and barley. | Infected grains become wrinkled and the remains will contain mycotoxins, which can poison livestock and humans. | | Maize | Stalk and ear rot | Discolouration and rotting of stem and ear | | Cattle | Deoxydivalenol toxicosis | Feed refusal, vomiting, poor growth and liver damage. | | Cattle | Zearalenone toxicosis. | Reproductive defects (including abortion) | | Humans | See cattle | See cattle |
|
|---|
| Virulence Factors:
| The mycotoxins deoxydivalenol (inhibits protein biosynthesis) and zearalenone (estrogenic mycotoxin). These mycotoxins can cause vomiting, liver damage and reproductive disorders in livestock, but are also dangerous to humans. |
