What test do I need?

If you are unsure what kind of tests you need, we can help you diagnose your crop using our plant diagnosis techniques.

  1. 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.
  2. 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.
  3. Tomato virus diagnosis screening
    Screen for a range of tomato viruses on symptomatic plant material via ELISA.
  4. 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.
  5. Blackcurrant reversion virus
    A test for blackcurrant reversion disease which is caused by a virus transmitted by the mite Cecidophyopsis ribis (blackcurrant gall mite or big bud mite).
  6. Strawberry tarsonemid mite (Phytonemus pallidus subsp. fragariae)
    Rapid identification of strawberry Tarsonemid Mites (Phytonemus pallidus fragariae) within your plant samples.
  7. Diagnose My Crop Problem
    We understand that every case is different and often you may not know the likely cause of the problem. For these cases we offer an examination of your sample by our crop health experts to assess the most probable cause.
  8. 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).
  9. 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.
