Resistance to powdery scab inSolanum tuberosum L.
American Potato Journal, 1964Seedlings and named varieties of potatoes were planted in five-hill lots in soil infested with the powdery scab organism. Over a three year period, the incidence of powdery scab varied considerably. In all three years, however, the Kennebec variety, used as a check, showed considerable infection indicating it to be very susceptible to this disease. The

Powdery Scab of Potato: A Diagnostic Guide
Plant Health ProgressPowdery scab, caused by Spongospora subterranea, is a soil- and tuber-borne disease of potato. The fungus-like protozoan pathogen can be found around the world and in almost every large potato-producing state across the United States. Initial signs of infection in the eyes and lenticels of tubers are slightly sunken, purple-brown lesions. When a tuber

Control of powdery scab of potatoes with chemical seed tuber treatments
New Zealand Journal of Crop and Horticultural Science, 1994Abstract Powdery scab, caused by Spongospora subterranea (Wallr.) Lagerh. f. sp. subterranea Tomlinson, has become an increasingly important problem on potatoes grown in New Zealand in recent seasons. During the 1992/93 season, the efficacy of 25 chemical seed tuber treatments against tuber‐borne inoculum of S.

Phytocytokine StPep1-Secreting Bacteria Suppress Potato Powdery Scab Disease
Phytopathology®Powdery scab is an important potato disease caused by the soilborne pathogen Spongospora subterranea f. sp. subterranea. Currently, reliable chemical control and resistant cultivars for powdery scab are unavailable. As an alternative control strategy, we propose a novel approach involving the effective delivery of a phytocytokine to plant roots by the

Incidence and severity of powdery scab on potatoes in Pennsylvania
American Potato Journal, 1988Studies were conducted in Potter Co., Pennsylvania to investigate the effect of powdery scab (Spongospora subterranea) on five potato cultivars (Norchip, Rosa, Kennebec, Katahdin, and Monona) at two planting dates. Soil temperature was within the range of 15–18 C and soil moisture was within 15–19% based on dry weight throughout the season.

Effect of 6-azauracil against apple powdery mildew and apple scab
Netherlands Journal of Plant Pathology, 1968In 1964 and 1965 trials were made with 6-azauracil (AzU) against powdery mildew and scab in an apple orchard at Kloetinge (Zeeland) and at Wageningen. The activity against scab was moderate, but against powdery mildew the results were better than those obtained with Karathane. The activity against mildew is ascribed to the systemic action of AzU, which

Resistance to powdery scab of seedling progenies ofSolanum tuberosum
Potato Research, 1991Tubers from individual seedlings of nineteen progenies involving eleven parental cultivars were tested for resistance to powdery scab over 2 years in artificially infested soil beds. There was a significant correlation between the mean resistance of a progeny and the phenotypic resistance of its parents.

Mitochondrial genome sequence of the potato powdery scab pathogen Spongospora subterranea
Mitochondrial DNA Part A, 2014Spongospora subterranea is a soil-borne obligate parasite responsible for potato powdery scab disease. S. subterranea is a member of the order Plasmodiophorida, a protist taxa that is related to Cercozoa and Foraminifera but the fine details of these relationships remain unresolved.
