Healthy and diseased wheat. Healthy wheat (Triticum sp.) head (left) compared to one infected with Fusarium graminearum fungus. The infected head shows severe symptoms of scab. Fusarium graminearum, also known as Gibberella zeae, is a plant pathogen and agricultural pest that causes wheat head blight disease. Fusarium head blight devastates wheat and barley (Hordeum vulgare) crops causing billions of dollars of losses worldwide each year. Infection causes the kernels to shrivel and contaminates the remaining grain with mycotoxins. These toxins cause vomiting, liver damage, and reproductive defects in livestock and are harmful to humans through contaminated food.
