eNews - October 2014


Welcome to the latest NGA newsletter and a snapshot of our Summer 2014/2015 trial plans. The Summer program covers a range of themes in weed and disease management together with general agronomy projects.

A comparison of harvest weed seed management options, prepared by the Australian Herbicide Resistance Initiative (AHRI) is also included together with information on two root-lesion nematode topics. The first highlights the recent updates to wheat variety resistance ratings and the second details the results from our recently completed survey on Pratylenchus thornei management and needs.

We hope you find the information useful. Once again, if you have any feedback (positive or negative) we would be glad to hear from you.

2014/2015 Summer Trial Projects

     Summer Fallow

2.  Residual Herbicides Plantback
3.  Knockdown of Grass Weeds
4.  Nitrogen Mineralisation and Fallow
     Water Efficiency
5.  Sorghum Herbicides
6.  Common Sowthistle Survey
7.  Scurvy Weed Management
8.  Root-lesion Nematode Management

Updated Wheat Resistance ratings to Pratylenchus thornei

In April, we sent out a document highlighting the tolerance and resistance ratings of key northern region wheat varieties to the root-lesion nematode Pratylenchus thornei.

Variety resistance ratings were updated in April 2014 and may differ from the ratings in current sowing guides. Where Pratylenchus thornei is of management concern, it is vital to avoid varieties classed as 'high risk' for either tolerance or resistance.

We have included another link to this document as it may be timely to assist with variety choices for seed retention.

AHRI: Spoiled Rotten 


Farmers these days are spoilt for choice when it comes to harvest weed seed control options. There are now five commercially available tools to remove weed seeds at harvest with a sixth in development. Luxury!

So if these systems all result in the same level of weed control, how do growers decide which is right for them?

2014 Root-Lesion Nematode Survey Results

NGA recently conducted an RLN survey as a follow-up to our 2010 baseline study. The aims were to assess the impact of project activity and to help identify industry needs for future research or extension focus.

Thank you to all who responded. The response rate exceeded 50% with a total of 79 individual responses.

If you are interested to participate in these ‘once a year’ surveys, please contact us at NGA Surveys.

The Challenge Continues

In 2013, NGA's Goondiwindi based Trials Agronomist Rachel Norton successfully completed the Sunshine Coast Tough Mudder fitness challenge. After much teasing - and the odd bit of coercion - it was decided to enter an NGA team in the 2014 event.

Unfortunately a remote wedding and a 'sniffle or two' meant only half the team participated with the photo below showing Linda Bailey, NGA's Darling Downs based Trials Agronomist, Nicole Carrigan, NSW DPI and Richard at the end of their extremely muddy ordeal.
To make up for their non-attendance, NGA's Brendan Burton together with Rachel and her husband Leigh, participated in the 21km Spartan Beast at Ipswich. They claim it made Tough Mudder look like a walk in the park ! Not to be outdone, Brendan's young daughters, Matilda and Lila, completed the Kids Spartan race.
