Powdery and Common scab both are potato blemish diseases that cause unsightly scab like blemishes on the tubers which in turn result in the tubers being rejected or downgraded.

These diseases share a range of symptoms which are solely applicable to the potato tubers themselves. There are no above ground symptoms.

This can cause significant financial implications for growers. Effective and timely identification of these diseases is critical as a result.

Common scab caused by the bacteria Streptomyces scabiei is prevalent across a range of potato varieties and can prove extremely costly to growers.

Powdery scab is a fungal blemish disease caused by Spongospora subterranea.

This test uses a visual exam to accurately identify which scab disease may be affecting your tubers.

If there are multiple scabs, the test will be performed on the predominant symptom unless instructed otherwise.

When sending plant pathogens and invertebrate samples from outside England and Wales for testing please email the Crop health team (crophealth@fera.co.uk) who will issue you with the relevant Letter of Authority to ensure your samples are not delayed upon entry to the UK.
