  1. Potato brown rot & ring rot (Official EU Protocol) - Ralstonia solanacearum & Clavibacter michiganensis subsp. sepedonicus
    This test is to detect the presence of Ring Rot and Brown Rot in potato tubers.
  2. Diagnose My Crop Problem
    We understand that every case is different and often you may not know the likely cause of the problem. For these cases we offer an examination of your sample by our crop health experts to assess the most probable cause.
  3. Tuber blemish diseases: visual assessment (% coverage)
    Our experts undertake a detailed visual assessment of your samples to report a percentage coverage of various tuber blemish diseases including: silver scurf, black scurf, skin spot, scab and black dot
  4. DNA sequencing of 16S rDNA or housekeeping genes
    DNA sequencing of 16S rDNA or housekeeping genes can be performed to identify bacterial isolates to a species or pathovar level. Testing can be performed on fresh isolates sent in to our labs or as an additional service to identify bacteria isolated from a sample sent in for testing.
  5. Soft rotting bacteria (Total count and Identification of Pectobacterium / Dickeya species)
    Blackleg is caused by a number of pectolytic bacteria, including Pectobacterium and Dickeya species, that have the ability to breakdown plant cell walls. It is a disease which affects all sectors of the UK potato industry.
  6. Soft Rotting Bacteria (average tuber inoculum load)
    This test provides a total count of soft rotting bacteria in potato tubers.
  7. Potato wash water test - Total count of soft rotting bacteria (Pectobacterium and Dickeya spp.)
    An overall count of soft rotting bacteria in potato wash water.
  8. Scab testing: powdery (Spongospora) & common (Streptomyces) - visual exam
    This combines a visual diagnosis with a molecular confirmation test.
  9. Fatty Acid Profiling
    Fatty Acid Profiling (FAP) is used to identify bacterial isolates and is accredited to UKAS ISO17025 standards. The profiles generated are compared against commercially available FAP libraries as well as our own in-house libraries generated using isolates from the National Collection of Plant Pathogenic Bacteria (NCPPB).
