Pest categorisation of non‐EU viruses and viroids of potato

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract Following a request from the EU Commission, the Panel on Plant Health has addressed the pest categorisation of those viruses and viroids (hereafter referred to as viruses) of Solanum tuberosum and other tuber‐forming Solanum spp. (hereafter referred to as potato) which are considered to be either non‐EU or of undetermined standing based on a ...

Powdery Scab of Potato Etiology, its Management through Chemical and Biological Methods [PDF]

Phytopathogenomics and Disease Control
Potato (Solanum tuberosum) production is significantly constrained by powdery scab, caused by Spongospora subterranea f. sp. subterranea (Sss), a soil-borne pathogen that also transmits Potato mop-top virus (PMTV).

Susceptibility of Solanum curtilobum to Spongospora subterranea (Wallr.) Johnson [PDF]

Nature, 1951
IT has been stated by Dorojkin1 that Solanum curtilobum and eight other South American species and varieties of Solanum are immune from Spongospora subterranea, the causal agent of powdery scab of potatoes; in this paper the number 8008 is linked with S.

Microscopical observations of the primary zoospores of Spongospora subterranea f.sp. subterranea [PDF]

Plant Pathology, 1997
A solution culture test system with Spongospora subterranea f.sp. subterranea spore ball inoculum and tomato bait plants was used to create a pulse of primary zoospore production and subsequent host‐root infection.

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.

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 ...

Long‐Read Metabarcoding With Optimized Bioinformatic Analysis Outperforms Short‐Read Metabarcoding for Assessing Soil Protist Diversity and Ecology

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Comparing 18S metabarcoding of protist cultures and environmental samples with short and long read sequencing highlighted the advantages of each method. In particular, the study of 26 vineyard soil samples with long reads showed high potential and reliability for ecological research with an increased sensitivity to environmental patterns.

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.

Occurrence of Zoosporangia in Spongospora subterranea, (Wallroth) Lagerheim [PDF]

Nature, 1935
ALTHOUGH powdery scab disease of potatoes has been known and studied for nearly one hundred years, zoosporangia have never been described in the life-history of the causal organism, Spongospora subterranea. Zoosporangia have, however, been observed in other genera of the Plasmodiophorales by Cook1 and by me2.

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.
