PreDicta pt

PreDicta Pt (Pt = potato) is a DNA-based soil testing service.

It identifies whether certain soilborne pathogens pose a significant risk to potato crops prior to planting.

PreDicta Pt tests provide you with an indication of the risk of:

  • Powdery scab (Spongospora subterranea)
  • Black dot (Colletotrichum coccodes)
  • Root knot nematode (Meloidogyne fallax).

They also provide indications of DNA level research results for:

  • Streptomyces txtA gene
  • Rhizoctonia solani AG3
  • Rhizoctonia solani AG2.1
  • Meloidogyne hapla
  • Verticillium dahliae
  • Pratylenchus penetrans
  • Pratylenchus neglectus
  • Pratylenchus crenatus.

The results are for information only. Sensitivity and risk categories are not available for these tests.
