GRDC Grains Research Update Wagga Wagga
Presented at:
The GRDC Updates deliver research direct to growers, agronomists and industry. This year the Updates will offer information from the latest research and development from short- and medium term investments that address on-farm priority issues from farming systems, agronomy, soils, weeds to pests and diseases.

Stress in not the problem, the problem is lack of recovery. Advisers will benefit from setting firm boundaries with their clients. Implementing ‘Go, Slow and No Zones’ may assist in boosting performance and preventing adrenal fatigue....

For pulses to play a role in sustainable and healthy food systems, key constraints through innovations in pulse-based food processing need to be addressed. • Research into material properties of pulses may reduce costly trial-and-error product development for ready to eat products. • Current research focus is to quantify how pre-treatment, formin...

Significant levels of resistance in ryegrass to post-emergent herbicides are present across all regions of New South Wales (NSW). • No resistance has been found to the newer ryegrass pre-emergent herbicides, Boxer® Gold and Sakura®, in the surveys carried out. • All weed species tested have some populations with resistance. • Despite significant le...

The frequency of winter cereals in a rotation impacts on the build-up of crown rot inoculum within paddocks. • Risk of losses can be minimised by monitoring inoculum levels over time and implementing management strategies to reduce them. • Crown rot can have negative impacts on grain quality and gross margins even without observing obvious symptoms...

Matching the supply of nitrogen (N) with crop demand is critical to optimising nutrient use and profitability of grain production. Defining the ability of a soil to deliver available N both prior to and within the grain growing season is required to help optimise N fertiliser application rates. • The amount of N delivered to crops from soil will be...

The global landscape for acceptable chemical use and residues is an increasing challenge which requires planning by industry, government and the commercial sector to meet future industry needs. • The Australian grains industry will need to consider adoption of more sophisticated chemical stewardship programs to increase access to crop protection t...

Inoculation of faba bean, lentil and field pea with rhizobia (Rhizobium leguminosarum bv. viciae) is critical on acid soils. Nodulation is improved by increased application rate of inoculation products. •The lower limit of pH(Ca) for reliable nodulation with the commercial strains of faba bean and field pea rhizobia is 5.0. • Liming to increase so...

Heading and flowering are considered the most sensitive stages for frost damage in cereals, however, damage can still occur from the onset of stem elongation and this can be reduced through management and variety selection. • Winter varieties have a long vegetative phase so have the lowest risk of damage from stem frost and although are not always ...

Rapid decision-support: CropScout is a new smartphone app which automates the sequential sampling process for cabbage and turnip aphids in winter/spring canola and maps results relative to the spray threshold, as a targeted sampling and spray decision tool. • This field intelligence can be used to optimise spray timing and, where possible, to targe...

How residual herbicide products react with soil, water, temperature, light, organic matter and microbes determine their potential for plant-back risk. • Drivers for pre-emergent residual herbicide breakdown are set by a product’s physical and chemical properties. • Labels are legal documents that provide guidelines and key conditions that when met ...
