Ergot is a fungal disease caused by fungi of the genus Claviceps. Species in this genus are unique in that they only infect ovaries of the host plants; no other part of the plant is infected. There are approximately 40 species of Claviceps with C. purpurea (Fries ex Fries) Tulasne being the species of greatest concern.

How do you treat ergot plants?

Management of ergot should include rotation with at least one year between small grain crops. Use crops that are not susceptible to ergot (e.g., soybeans, alfalfa, corn) in years when small grains are not grown. Plant seed that is free of ergot sclerotia.

Does ergotism still exist?

In less wealthy countries, ergotism still occurs; an outbreak in Ethiopia occurred in mid-2001 from contaminated barley. Whenever there is a combination of moist weather, cool temperatures, delayed harvest in lowland crops and rye consumption, an outbreak is possible.

What is ergot How does it grow and where?

This fungus grows on rye and related plants, and produces alkaloids that can cause ergotism in humans and other mammals who consume grains contaminated with its fruiting structure (called ergot sclerotium). Claviceps includes about 50 known species, mostly in the tropical regions.

Did ergot cause the Salem witch trials?

Ergot sclerotia are purple-black growths that contain lysergic acid and ergotamine. According to this theory, the abrupt end of the witch trials in May 1693 happened, quite simply, because Salem ran out of ergot-contaminated grain.

Why is ergotism called St Anthony’s fire?

The frequent epidemics of ergotism were called Holy Fire or st-Antony’s Fire in the Middle Ages, because of the burning sensations resulting in gangrene of limbs. It was caused by eating rye bread contaminated with the fungus Claviceps purpurea.

Can ergotism be cured?

There is no antidote, so treatment involves removing the animals from the source of the ergot and alleviating the symptoms. If found early enough and before severe clinical signs develop, animals can recover, but once gangrene has started, there is little treatment.

How do I know if my ergot has fungus?

Early ergot fungus symptoms in grains and grasses are very hard to detect, but if you look at their flowering heads closely, you may notice an unusual shimmering or sheen caused by a sticky substance coming from infected flowers. This honeydew contains a huge number of spores ready to spread.

How does ergot disease of bajra affect plants?

Primary infection on healthy crop plants is brought into being after the sclerotia germinate in about a month’s time. The sclerotia germinate producing stripes, which bear perithecial heads that contain many perithecia embedded in them. Perithecia represent the fruiting bodies of the fungus and produce many asci inside.

How does ergot affect the production of Rye?

The disease decreases the production of viable grains by infected plants and can contaminate harvests. Ergot is commonly associated with rye infected by C. purpurea, but other economically important cereals are also susceptible to the disease by other fungal species.
