Abstract

Procédé pour la production agricole de l'ergot par infection d'une graminée à l'aide de spores d'ergot et récolte du sclérotium de l'ergot mûr. On applique à la graminée, avant infection par les spores de l'ergot, un gamétocide chimique en quantité suffisante pour provoquer une stérilité appréciable de la plante. On a constaté que le traitement par le gamétocide conduisait à une production d'ergot à des rendements élevés. On sait que les alcaloïdes de l'ergot ont des usages médicinaux.A method for the agricultural production of ergot by infecting a grass with ergot spores and harvesting sclerotium from mature ergot. Before infection with ergot spores, a chemical gametocide is applied to the grass in an amount sufficient to cause appreciable sterility of the plant. Gametocide treatment has been found to lead to ergot production in high yields. Ergot alkaloids are known to have medicinal uses.
