DPIRD research scientists Esther Walker and Dr Amanuel Bekuma examine a specimen for a new  qPCR test to identify and quantify ice nucleating bacteria, which elevate the frost risk to plants.

The Department of Primary Industries and Regional Development (DPIRD) developed the test, based on the discovery of a molecular marker to identify and quantify ice nucleating bacteria (INB) that elevate the risk of frost damage.  DPIRD research scientist Esther Walker said the great advantage of the INB qPCR test was that it could be undertaken in the paddock in just 40 minutes, compared with the conventional process that takes at least a week.  Read more in 10 June 2022 DPIRD Media Release COOL NEW FROST TEST
