Ergot Alkaloid Contents in Hybrid Rye are Reduced by Breeding
Agriculture, 2021 Contamination by ergot caused by the phytopathogenic fungus Claviceps purpurea is a constant threat to the whole rye value chain. Ergot alkaloids (EA) produced within the fungal sclerotia are toxic for humans and animals and are subjected to strict ...

Immersion of grains in a liquid along an inclined plane [PDF]
E3S Web of Conferences, 2021 Grain material delivered from combine harvesters to post-harvest processing points is a mixture of grain, weed and harmful impurities. Toxic ergot sclerotia are among the harmful impurities. Modern grain cleaning machines do not provide the separation of

Ergochromes: Heretofore Neglected Side of Ergot Toxicity
Toxins, 2019 Ergot, fungal genus Claviceps, are worldwide distributed grass pathogens known for their production of toxic ergot alkaloids (EAs) and the great agricultural impact they have on both cereal crop and farm animal production.

Effect of Field-applied Fungicides on Claviceps purpurea Sclerotia and Associated Toxins in Wheat
Journal of Food Protection, 2023 Claviceps purpurea (Fr.) Tul is the causal organism for ergot impacting grass hosts, including wheat. The pathogen produces ergot alkaloids (EAs) during the development of mature sclerotia leading to potential wheat quality discounts or rejection at the ...

Vasoactive Effects of Acute Ergot Exposure in Sheep
Toxins, 2021 Ergotism is a common and increasing problem in Saskatchewan’s livestock. Chronic exposure to low concentrations of ergot alkaloids is known to cause severe arterial vasoconstriction and gangrene through the activation of adrenergic and serotonergic ...
