Resistance to powdery scab inSolanum tuberosum L.

American Potato Journal, 1964
Seedlings 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

2022
Because there are very few effective ways to manage the disease, it’s crucial to know how to minimize the risk of an outbreak. This five-page bulletin discusses the signs and symptoms, the pathogen’s disease cycle and the management options available.

Incidence and severity of powdery scab on potatoes in Pennsylvania

American Potato Journal, 1988
Studies 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.

Screening for resistance to powdery scab disease of potatoes.

Australian Journal of Experimental Agriculture, 1986
Powdery scab disease of potatoes, caused by the fungus Spongospora subterranea, has developed as an important disease of potatoes in Victoria because of changes in agronomic practices, such as increased supplementary irrigation, earlier planting and increased use of the highly susceptible cultivar Kennebec.

Resistance to powdery scab of seedling progenies ofSolanum tuberosum

Potato Research, 1991
Tubers 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.

The effect of irrigation and nitrogen on powdery scab and yield of potatoes

Potato Research, 2002
Powdery scab, caused by the fungusSpongospora subterranea, has developed in the Cappodocia region of Turkey because of changes in agronomic practices, such as excessive irrigation and nitrogen fertilizer use and growth of highly susceptible cultivars. The most suitable irrigation and nitrogen application levels were established to maintain powdery scab

The Control of Scab and Powdery Mildew of Apple with a Reduced Number of Sprays

Plant Pathology, 1975
SUMMARY Apple scab was effectively controlled with either benomyl (0·025 per cent a.i.), thiophanate‐methyl (0·05 per cent a.i.) or carbendazim (0·025 per cent a.i.) applied at 21‐day intervals. Where powdery mildew was a problem, it was necessary to interject into this programme additional sprays of either binapacryl (0·05 per cent a.
