Microbial degradation of propyzamide – will we have a problem?

Mon, 31 Jul 2017

Some excellent research conducted by Stephen Hole, under the watchful eye of Professor Steve Powles at the University of Adelaide in the mid-1990’s investigated the microbial degradation of propyzamide and another similar herbicide, carbetamide. Enhanced microbial degradation is where the soil bacteria that can eat a particular herbicide build up to very high levels so when the herbicide is applied it is broken down very quickly, effectively reducing the half-life of the herbicide.

Publications High levels of adoption indicate that harvest weed seed control is now an established weed control practice in Australian cropping

Not so long ago, harvest weed seed control (HWSC) was only used by a minority of early adopting grain growers. Now it has gone mainstream and pretty soon just about everyone will be doing it.

This is the result from a national Australian GRDC grower survey reported in a recent scientific publication by Michael Walsh from University of Sydney. Every few years GRDC fund a large grower practices telephone survey. The most recent survey was conducted by CSIRO in 2014, and they collaborated with Michael to design the HWSC questions.
