" Goondiwindi GRDC Grains Research Update Day 1 - Tuesday 4 th March Time Topic Speaker (s) 10:00 AM James Clark (Chair Northern Welcome Panel GRDC) 10:10 AM General plenary (Supported by North West Local Land Services) 10:10 AM 10:40 AM.. Overall, both models are acceptable for modelling soil evaporation over a range of soils and seasons provided accurate soil physical properties and starting water states are known... Overall, populations increased five times compared to before planting the summer crops, but remained below 250/kg soil (Figure 4)...

Weed seeds will most likely absorb herbicide if the herbicide is at or below the seed in the soil profile... Triallate needs to be situated at or above the weed seed to be effective... It is c4 u recommended that a preliminary compatibility test (jar d3 e 0 Tordon* ^^ R test) be carried out prior to the use of any tank mix t 20 with AXIAL n Velocity* e1 Please refer to the label of the product being tank c 0 r e mixed for rates and constraints P 0 GS39 GS47 - 49 GS61 - 65 Product labels and usage directions should be followed for the application of any product referred to in this Avena Growth Stage at Application publication...

Disc seeding system design and settings, including operating and sowing depths and travel speed, all appear to influence behaviour of pre-emergence herbicides and can play a critical role in minimising crop damage... The use of residue managers ahead of single disc blade openers has shown to significantly improve the level of crop safety... Preliminary results from trials undertaken last year showed that disc seeding system setup also has a critical role in the level of wheat crop damage from pre-emergence herbicides...

Pre-emergent herbicides typically have more variables that can affect efficacy than post-emergent chemistries and if not applied strategically, can result in poor crop emergence... Knife-point and press wheel seeders have been widely adopted and more recently, disc seeders have also been utilised... Research associate from the University of Adelaide's School of Agriculture, Food and Wine, Dr Sam Kleemann told advisors and growers attending the recent GRDC Grain Research Updates in Coonabarabran and Warren that the physical separation of crop seed and herbicide was imperative if crop damage was to be avoided...

No pre-emergent herbicide in Australia has on-label recommendations for disc seeders.. The study, conducted by the University of Adelaide and University of South Australia with support from the Grains Research and Development Corporation (GRDC), aims to refine the industry's understanding of the use of disc seeders in conjunction with pre-emergent herbicides and inform future on-label advice... University of Adelaide researcher Sam Kleemann said although growers increasingly recognised the advantages of disc seeders, many pre-emergent herbicides' on-label advice forbids use alongside disc seeders, and chemical companies often won't support the use of disc seeders because of a lack of information around the machinery's impact on crop safety...

A submission has been made to the APVMA for registration of Roundup Attack with IQ inside used pre-harvest in canola - a new use pattern for Australian canola growers... A submission was made to the APVMA in June 2012 to register Roundup Attack with IQ inside for pre-harvest use in canola... We are hoping to provide growers with the flexibility to control weed seed set in canola with robust rates of Roundup Attack with IQ inside...

1. The use of a disc planter for incorporation by sowing (IBS) of residual herbicides resulted in significantly reduced wheat emergence for all four herbicides evaluated.. The approach helps to ensure sufficient soil is thrown across the inter-row space to effectively 'incorporate' the herbicide, plus it removes most of the herbicide treated soil from the planting furrow to improve crop safety... An unregistered PSPE application of Boxer Gold was also evaluated in both trials...
