Towards biological control of Spongospora subterranea f. sp. subterranea, the causal agent of powdery scab in potato [PDF]

Australasian Plant Pathology, 2017
Powdery scab of potato, caused by the obligate biotrophic protozoan pathogen Spongospora subterranea f.sp. subterranea (Sss), is a major problem in potato growing areas throughout the world. It results in lesions (scabs) on the surface of the tubers which renders them unmarketable.

Foliar treatments of 2,4-dichlorophenoxyacetic acid for control of common scab in potato have beneficial effects on powdery scab control. [PDF]

ScientificWorldJournal, 2014
Prior studies have shown that applications of the synthetic auxin 2,4‐dichlorophenoxyacetic acid (2,4‐D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4‐D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab.

Effects of Different Soil Treatments on the Development of Spongospora subterranea f. sp. subterranea in Potato Roots and Tubers in the Greenhouse [PDF]

Potato Research, 2017
Powdery scab caused by Spongospora subterranea f. sp. subterranea (Sss) causes extensive losses in potato production systems globally. Two pot experiments were established in the greenhouse in summer 2013 and winter 2014 to evaluate the effectiveness of different soil chemicals, fumigant, amendments and biological control agents (BCAs) against Sss in ...

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 ...
