Sorghum Ergot: Distinguishing Sphacelia and Sclerotia of Claviceps africana in Seed
MetadataShow full item record
The field symptoms of sorghum ergot are familiar to anyone involved in sorghum production. It is more difficult to identify the fungal pathogen in seed because there is a lack of understanding about the structure and function of sphacelia and sclerotia. This publication uses color photographs to differentiate between sphacelia and sclerotia and immature, cracked and moldy seed and other foreign objects.
