  1. Pea bacterial blight - Pseudomonas syringae pv. pisi - Pea seed
    Test for Pseudomonas syringae pv. pisi, more commonly known as pea bacterial blight. Infection causes water-soaked spots which may coalesce into larger lesions.
  2. 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.
  3. 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).
  4. Tomato mosaic virus by ELISA - Seeds
    Tomato mosaic virus (TMV), is an infection that can cause yellowing and stunting of tomato plants, resulting in reduced yield and may cause uneven ripening of fruit.
  5. Pepino mosaic virus in seed by ELISA
    Pepino mosaic virus (PepMV) affected tomatoes show distorted leaf development, with bubbling of the leaf surface and chlorosis.
  6. Black Rot - Xanthomonas campestris pv. campestris - Brassica
    Xanthomonas campestris pv. campestris, more commonly known as black rot, can be found across a range of host plants, infecting all cultivated Brassicas. This includes cabbage, cauliflower and mustard varieties.
  7. Strawberry tarsonemid mite (Phytonemus pallidus subsp. fragariae)
    Rapid identification of strawberry Tarsonemid Mites (Phytonemus pallidus fragariae) within your plant samples.
  8. Xanthomonas hortorum pv. carotae - Carrot seed
    Xanthomonas hortorum pv. carotae, more commonly known as the bacterial blight of carrot.
  9. Standard growing on test for virus in Potato
    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 in Potato
    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)
    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.
