Enzyme enters the fight to keep run-off water herbicide free

Atrazine is a widely used and useful herbicide used to stop broadleaf and grassy weeds in major crops. The downside, depending on its use, is that residue can make its way into run-off water. This has been a particular problem overseas, and in some cases, it’s led to restrictions being placed on the use of atrazine in the EU and USA.
This situation is set to change thanks to a research team from CSIRO Entomology, and farmers around the world are expected to benefit from the successful trial of an enzyme that breaks down atrazine, in run-off water.
In this Podcast, Cameron Begley, General Manager, Business Development and Commercialisation at CSIRO Entomology explains how the enzyme works in breaking down residual atrazine, and how the search for the enzyme began with a hunt for bacteria that ‘fed’ on atrazine.
