Studies on Claviceps parasitic on Panicum species in India.

Panicum repens and P. antidotale were found to be infected with Claviceps sp. This is the first report of ergot on P. repens. The pyrenomycete produced abundant sclerotia on the host plants. The sclerotia contained 0.71 and 0.68% alkaloids, respectively, which predominantly consisted of chanoclavine, festuclavine and agroclavine. The infected grasses were possibly mycotoxic. Submerged cultures of Claviceps strain isolated from Panicum spp. produced significant amount of chanoclavine, festuclavine and agroclavine. No pharmaceutically important alkaloid was found in sclerotia or in submerged culture.
