Welcome to the latest NGA Newsletter and a snapshot of our 2016/2017 Summer Trials. Our program focuses on a broad range of topics, details can be found by selectingView our Trial Snapshots.

There are also links to information on:
  • Preliminary results from Fallow Water Efficiency activity;
  • Why is Herbicide Resistance slower to develop in Wild Oats?
  • GRDC Opportunities.
In addition, there is a request for help to find suitable sites for Sowthistle management trials.

We hope you will find the information useful and welcome any feedback.

Desperately Seeking Sowthistle

Sowthistle is a weed of increasing concern in the northern grains region due to a combination of:
  • Widespread distribution and nearly year round habit;
  • Wind-borne seed spread; 
  • Increasing levels of glyphosate resistance. 
NGA has a large sowthistle management focus this summer.  Sites are currently being sought in the Moree/Goondiwindi and Darling Downs regions to assess residual and knockdown control in fallow.

Impacting Fallow Water Efficiency

At a recent Mungindi Cropping Group Field Day, Rachel & Denielle presented soil moisture data from a trial which commenced at “Bullawarrie’’ in November 2015.  

Push probe results in June showed an extra 6-8cm of moist soil under all treatments where stubble had been added to provide additional groundcover.

However, capacitance probe findings, comparing standing stubble to the 40 t/ha added groundcover treatment, provided the most dramatic results.  Read more to see what was found.

Herbicide Resistance in Wild Oats

AHRI researchers have gathered more information which explains why wild oats appear slower to develop herbicide resistance.  

GRDC Opportunities

GRDC is currently offering three opportunities for grains industry development:
  • Support for group study tours, both domestically and internationally;
  • Support for short courses or attendance at industry training or conferences; 
  • Investment in two types of scholarships to drive innovation in the grains industry.  Applications close on 31 October.
