Abstract

Sclerotia of the cotton root rot fungus, Phymatotrichum omnivorum, have been consistently obtained in sterile-soil cultures with a nutrient added, such as seeds of sorghum, cotton, bean, or cowpea. This method has been found effective under a wide range of moisture, nutrient, temperature, and soil conditions. Variations in size of sclerotial masses were noted with different types of nutrients and when sand was used in place of soil.
