Crown Analytical Services partnered with SARDI in 2011 to service their PREDICTA® B soil and stubble borne disease DNA test in the northern growing region. Dr Alan McKay and his team at SARDI have been at the forefront of this development, the test being the result of 30 years of research.

It provides a simple and efficient testing process, where one soil sample can be analysed for multiple diseases. The list of diseases available for testing continues to expand, with yield risk ratings being developed through research. You can access the latest yield loss risk categories here.
