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).

Single Cystosorus Isolate Production and Restriction Fragment Length Polymorphism Characterization of the Obligate Biotroph Spongospora subterranea f. sp. subterranea [PDF]

Phytopathology®, 2006
Spongospora subterranea f. sp. subterranea causes powdery scab in potatoes and is distributed worldwide. Genetic studies of this pathogen have been hampered due, in part, to its obligate parasitism and the lack of molecular markers for this pathogen.

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

First Confirmed Report of Powdery Scab Caused by Spongospora subterranea f. sp. subterranea on Potato in Sri Lanka

Plant Disease, 2011
White, wart-like outgrowths on roots and stolons – root galls – and blisters and pustules on tubers (lesions) are characteristic symptoms of the potato powdery scab disease caused by Spongospora subterranea (Wallr.) f. sp. subterranea. In Sri Lanka, potato is a major cash crop primarily in two agroecological zones of higher altitude, Nuwara Eliya and ...

First Report of Potato Powdery Scab, Caused by Spongospora subterranea f. sp. subterranea, in North Dakota

Plant Disease, 1997
Powdery scab is a serious disease of potatoes (Solanum tuberosum L.) that can cause extensive surface defects on susceptible potato cultivars. The pathogen, Spongospora subterranea (Wallr.) Lagerh. f. sp. subterranea J. A. Tomlinson, is an important concern in seed potato production because current seed certification standards in North Dakota have a ...

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

First Report of Powdery Scab, Caused by Spongospora subterranea f. sp. subterranea, on Potatoes in Crete, Greece

Plant Disease, 2014
In February 2013, severe symptoms of the powdery scab canker type were observed during harvesting at the Mallia area of Heraklio, Crete, Greece, on approximately 20% of the tubers of two commercial smooth skinned potato (Solanum tuberosum L.) field crops (cv. Spunta), of which the seeds had been imported from the Netherlands. Initially, small (up to 2
