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.
