  1. Pospiviroid seed testing package (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.

  2. Potato spindle tuber viroid (PSTVd) seed testing package (1500 seeds)

    Potato spindle tuber viroid (PSTVd) effects tomato, pepper and other solanaceous hosts. Symptoms include stunting, severe yellowing and distortion of the leaves. PSTVd is seed transmitted. 1500 seeds are tested for Potato spindle tuber viroid (PSTVd) by real time RT-PCR (TaqMan). However, this TaqMan assay also detects Tomato chlorotic dwarf viroid (TCDVd), Mexican papita viroid (MPVd) and Tomato planta macho viroid (TPMVd).

  3. Standard growing on test for virus in Potato (PVY + 3 viruses)
    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.
  4. Identification and confirmation of pospiviroid seed positive

    Pospiviroid positives detected by real time RT-PCR (TaqMan) are tested by RT-PCR and sequencing to try to identify and confirm the pospiviroid.

  5. Rapid direct tuber test for virus in Potato (PVY + 3 Viruses)

  10. Standard growing on test for virus in Potato (PVY + 6 viruses)
    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.
  11. Standard growing on test for virus in Potato (PVY + 8 viruses)
    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.
  12. Rapid direct tuber test for virus in Potato (PVY + 2 Viruses)
