  1. Alternaria spp. Seed Test

    Test to detect the presence or absence of the genus Alternaria in Seeds.

    A quantitative test is available on request.

  2. 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.

  3. 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.

  4. 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).

  5. 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.

  6. Angular leaf spot (Xanthomonas fragariae) - Option 2
    Angular leaf spot is a disease in strawberries caused by the bacterial pathogen Xanthomonas fragariae.
  7. Angular leaf spot (Xanthomonas fragariae) - Option 1

    A latent test for a bacterial disease affecting strawberries caused by Xanthomonas fragariae.

  8. Barley yellow dwarf virus and Soil borne cereal mosaic virus

    This testing for cereal crops covers both Barley yellow dwarf virus (BYDV) and Soil-borne cereal mosaic virus.

  9. Cereals: Barley mild mosaic virus and Barley yellow mosaic virus
    Barley yellow mosaic virus and Barley mild mosaic virus are pathogenic viruses which cause yellow mosaic disease of winter barley.
  10. Crown Gall Disease (Tumor-Inducing Plasmid) Testing
    A test for Rhizobium radiobacter (formerly known as Agrobacterium tumefaciens), which is responsible for crown gall disease in plants. The bacterium enters the plant through wounds in roots or stems and stimulates disorganised tissue growth, producing swollen galls.
  11. Pospiviroid screen
    A PCR screen to identify the presence of a number of popsiviroids in symptomatic plants/leaves including Potato spindle tuber viroid, Tomato chlorotic dwarf viroid, and Columnea latent viroid.
  12. Soft Rotting Bacteria (average tuber inoculum load)
    This test provides a total count of soft rotting bacteria in potato tubers.
