  1. 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.
  2. 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.

  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. 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.
  5. Gangrene Latent Test
    A latent test for gangrene, a slow growing fungal disease of stored potatoes, caused by Boeremia foveata.
  6. 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.
  7. Additional pospiviroid seed testing (1500 seeds)

    Pospiviroid positives detected by real time RT-PCR (TaqMan) are tested by RT-PCR and sequencing to try to identify and confirm the pospiviroid - this is a supplementary test to our standard Pospiviroid seed testing package.
