    Many plant species are susceptible to infection by foliar parasitic nematodes, leaf and bulb nematodes (Aphelenchoides spp.) and stem nematode (Ditylenchus dipsaci).

  6. Tomato root mat disease (Root-inducing plasmid) testing
    A test for Tomato Root Mat Disease caused by Rhizobium rhizogenes, a gram-negative soil bacterium that contains root-inducing (Ri) plasmids which can lead to over-abundant growth of roots in tomatoes and cucumbers.
  7. Identification of Trichoderma aggressivum on compost
    Test for Trichoderma aggressivum, which can infect and colonise healthy, productive mushroom compost. It causes compost green mould in Agaricus.
  8. Standard growing on test for virus in Potato (PVY)
    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.
  9. Rapid direct tuber test for virus in Potato (PVY)
    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.

  10. 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
