  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. 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).
  3. Soft Rotting Bacteria (average tuber inoculum load)
    This test provides a total count of soft rotting bacteria in potato tubers.
  4. 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.
  5. Potato spindle tuber viroid by TaqMan® - Seeds

    The common symptoms of Potato spindle tuber viroid (PSTVd) can include stunted growth and changes in the foliage colour in extensively affected crops.

  6. Potato & Beet Cyst Nematodes (PCN & BCN): extraction from soil

    An ISO accredited test for the extraction and identification of potato cyst nematode (PCN) species Globodera rostochiensis and Globodera pallida from soil.

  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. Spraing test for symptomatic tubers (tobacco rattle virus & potato mop top virus)

    Tests for the 2 viruses responsible for spraing, the nematode transmitted Tobacco rattle virus (TRV) and the Powdery scab transmitted Potato mop top virus (PMTV)

  9. Standard growing on test for virus
    This growing on test takes six to eight weeks where tubers are grown on in the glasshouse and subsequently tested for various PVY strains and any specific viruses as requested using ELISA.
  10. Rapid direct tuber test for virus
    This rapid direct tuber test includes Potato virus Y (PVY) as standard.

    Further viruses are available for an additional fee. These are Potato leaf roll virus (PLRV) and potato viruses PVA, PVV and PVX.

  11. 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
  12. Scab testing: powdery (Spongospora) & common (Streptomyces) - visual exam
    This combines a visual diagnosis with a molecular confirmation test.
