The disease is caused by soil bacteria, including Actinomyces scabies, Actinomyces cretaceus, Actinomyces nigrificans, and Bacillus scabiegenum. The pathogens infect the epidermis of the root crop, leading to the formation of characteristic lesions.
Three forms of the disease are distinguished in sugar beet. Common scab is characterized by scab-like cracks and corky outgrowths. Girdle scab manifests as specific annular constrictions in the middle part of the root, often following blackleg infection. The pustular form appears as warty brown outgrowths in the upper part of the root, which can develop into ulcers.
