Blackleg is consistently the major cause of downgrading and rejections in the Scottish Seed Potato Classification Scheme. It has a direct impact on the quality of the potato crop and can have severe financial implications for growers if not adequately managed.
It is one of the earliest potato diseases to appear, especially in wet years. Fera's high quality testing can ensure that you receive an accurate identification.
It is important to maintain the high quality crop valued by your customers. This can also help you maintain yield and therefore reduce any financial implications as a result of this disease.
When sending plant pathogens and invertebrate samples from outside England and Wales for testing please email the Crop health team (firstname.lastname@example.org) who will issue you with the relevant Letter of Authority to ensure your samples are not delayed upon entry to the UK.
A number of bacterial pathogens are capable of causing rots of potato tubers, most importantly during storage of the crop. The pathogen found most frequently in the UK is Pectobacterium carotovorum , but Pectobacterium atrosepticum and Dickeya species may also be involved.Tuber rotting can also develop following infection by the quarantine organisms Ralstonia solanacearum (brown rot) and Clavibacter michiganensis subsp. sepedonicus (ring rot). The majority of growers will, hopefully, never see either of these diseases, but should be aware of their symptoms.
