Welcome to a new format for NGA communication.

We hope to utilize this style of approach for future Newsletters and also Project Reports to improve both our efficiency but also timeliness of communication. The appointment of Kim Thomas (see side article) will greatly improve our ability to manage these regular communications whilst also responding to an apparently ever increasing need for technical project activity!

We would greatly appreciate any feedback (positive or negative) on this approach as we strive to make the project outcomes easier for you to access whilst also simpler for us to administer.

  2011 Winter Trials Snapshots

A site has been established in the Weemelah area to evaluate the impact of Pratylenchus thornei on the yield of a wide range of winter crop species and varieties.  All varieties are being evaluated under both high and low P thornei pressure.  The crop and variety impact on P thornei multiplication will also be assessed together with the combined impact of crown rot and P thornei

Two trials will be conducted in the Moree/Narrabri and Walgett areas to compare disease development and yield impact from a range of fungicide strategies.  Strategies will be benchmarked against a standard mancozeb approach. Key disease targets are rust and chocolate spot.

Six trials will be conducted to evaluate disease development, yield and grain quality impact from a range of fungicide strategies. Trials are expected to be conducted in commercial paddocks of Grout to limit other disease interactions. Trials will include single and multiple spray regimes.  

Three trials are planned to compare a range of products which will be applied ~ 3 weeks prior to harvest. Product choice, rate and water volume will be the key focus in determining whether these products have a fit to reduce shattering losses and possibly allow more direct heading. 

Three trials are planned to investigate product rate and water volume with aim of reducing grain quality losses due to weather damage and potentially lowering shattering losses.  Intention is to conduct trials in commercial paddocks but induce weather damage under controlled conditions on samples taken from the paddock. 

Four trials are planned to screen a range of winter crop grass selective herbicides for activity against feathertop Rhodes grass. Trials are likely to be conducted in fallow situations on early spring germinations. A range of group A and B chemistry is being evaluated.   

Four trials are planned to compare a range of in-crop herbicide approaches to assist in the management of fleabane. Growers and agronomist are keen to examine alternative programs that can help reduce the issues, cost and difficulty of controlling fleabane in the summer fallow. Three trials have already commenced with PSPE applications. 

Three trials are planned to determine the impact of water bicarbonate and hardness levels on the control of fleabane with glyphosate/ 2,4 D amine treatments.  Trials will also examine the fit of ammonium sulphate to assist in improving fleabane control reliability.  

Three trials are being conducted in collaboration with Dr Kevin Moore (NSW DPI). A range of seed treatments are being compared for the control of seed-borne Botrytis seedling blight. Planting seed has been sourced from paddocks badly infected with Botrytis grey mould in 2010.  Exciting results have already been found. 

Five trials are planned to complete a project commenced in 2009. Pathology results have consistently shown some promising impacts on stem browning and crown rot incidence. Plan is to gather more information on pathology, yield and grain quality to help determine whether these approaches are economic.

NGA Staff Changes

We are very pleased to announce two new staff members have recently joined the NGA  team -
RACHEL HERRON is the new Trials Agronomist who will be based at Goondiwindi and will cover the Goondiwindi and Mungindi/ Balonne areas. Rachel comes from a rural background with her parents on a property near Crow’s Nest. She had 4 years’ experience in seed production with Pacific Seeds as well as roles in both cotton and horticulture. She was most recently working as a Seeds Analyst with SGS Australia.  Rachel ‘s contact details are listed below –
PO Box 124
Mobile:  0447 924 917


KIM THOMAS is our new Office Administrator, who works out of the Toowoomba office one day per week.  Kim is certainly handling a considerable amount of our administration workload and should also help to improve our efficiency and the timeliness of communcation.  Kim has extensive experience in office administration with most of her background in legal firms and with almost 10 years’ experience with United Graziers’ Association and AgForce Queensland.    Kim can be contacted on –

Office: (07) 4639 5344

 NGA Wedding Bells

 Congratulations are in order for NGA Trials Agronomist, Anthony Mitchell, who was married on the 9thof April.  He and his wife, Sarah, have had little time to settle into married life as Sarah has had a very busy few months, having recently been elected to the NSW Parliament as a Member of the Legislative Council - the Upper House in NSW.

The Hon. Sarah Mitchell MLC and Anthony are a couple who don’t do things by halves. Whilst balancing wedding preparations, elections and trial commitments they also managed to relocate from Moree to Gunnedah to start their married life. We wish them well


Trials Agronomist Territories

With Ant’s relocation and the appointment of Rachel, we have realigned Trials Agronomist territories.

Ant will cover the Liverpool Plains and areas south of the Gwydir Highway from Narrabri out to Walgett.

Rachel will cover north of the Gwydir highway and include Mungindi/ St George and the Westmar / Moonie areas.

Rob will continue to cover the Darling Downs and areas west of Dalby.
