Advancements in Spongospora subterranea: Current Knowledge, Management Strategies, and Research Gaps

Potato Research
Powdery scab was first documented on locally sampled potatoes in Braunschweig, Germany. A hundred and eighty-one years later, the disease has spread globally to most potato-producing regions and is considered one of the most destructive potato diseases ...

Pest categorisation of Thecaphora solani

EFSA Journal, Volume 16, Issue 10, October 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of the fungus Thecaphora solani, the causal agent of smut of potato, for the EU. The identity of the pest is well established and reliable methods exist for its detection and identification. T.

Pest categorisation of Synchytrium endobioticum

EFSA Journal, Volume 16, Issue 7, July 2018., 2018
Abstract The Panel on Plant Health performed a pest categorisation of the fungus Synchytrium endobioticum, the causal agent of potato wart disease, for the European Union (EU). The identity of the pest is well established and reliable methods exist for its detection and identification. S. endobioticum is present in most continents.

Establishing the Host Status of Various Cover and Rotation Crop Species to the Soil-Borne Pathogen, Spongospora subterranea f. sp. subterranea, in South Africa

Potato Research
Spongospora subterranea f. sp. subterranea (Sss) is the causal agent of the potato tuber disease, powdery scab. Sss infects a wide range of species, often used for cover cropping or as rotation crops.

Recent Advances in Biology, Epidemiology and Host Resistance to Potato Powdery Scab

Plant Pathology, Volume 75, Issue 3, May–June 2026.
This review highlights recent advances in understanding powdery scab and potato resistance, providing new perspectives for developing durable and integrated strategies to manage the disease. ABSTRACT Powdery scab of potatoes (Solanum tuberosum) is caused by the soil‐borne protist Spongospora subterranea f. sp. subterranea (Sss).

Resistance to Multiple Tuber Diseases Expressed in Somaclonal Variants of the Potato Cultivar Russet Burbank

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Multiple disease resistance is an aim of many plant breeding programs. Previously, novel somatic cell selection was used to generate potato variants of “Russet Burbank” with resistance to common scab caused by infection with an actinomycete pathogen. Coexpression of resistance to powdery scab caused by a protozoan pathogen was subsequently shown.
