Exploring Spongospora suppressive soils in potato production


Project Number:


Project Status:


Update Date:



This work is being done in collaboration with Plant Health Australia and is examining field soils to determine if they suppress or encourage the quality- and yield-limiting potato diseases caused by Spongospora subterranean. These diseases include tuber powdery scab, root malfunction and root galling. Biological, chemical and physical soil factors are being measured in potato-growing field soils, and potential mechanisms for disease suppression are being assessed. The transferability of specific characteristics tonon-suppressive soils will be evaluated, to determine the potential for manipulating soil factors as a management strategy for Spongospora diseases.
