Overview

This 4-page publication uses color photographs to differentiate between sphacelia and sclerotia and immature, cracked, and moldy seeds and other foreign objects.

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 seeds and other foreign objects. (4 pages)
