AIMS:
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.
Trials demonstrate good levels of annual ryegrass seed set control – providing growers with another tool for weed seed management.
Application can be made over the top of standing canola (prior to direct harvest) or applied under the windrower/swather with specialized spray equipment.

Climate data and weather forecasts are both valuable in informing grain growers of system status (e.g. soil water, heat sum) and probabilities of future events (e.g. rainfall, temperature extremes).
Analyses are now available in an iPhone/iPad App, CliMate, and web based tools, providing ready access to site specific climate information.

Low protein in cereal grains is indicative of poor nitrogen supply to the grain during the grain fill period. This is influenced by factors such as the location and concentrations of mineral nitrogen resulting from fallows and application of fertilisers, fallow soil moisture amount and soil profile distribution, seasonal rainfall and temperature patterns, and crop species and varietal genetics. Contributing factors in the 2012 crop included:
• Long term loss of soil nitrogen supply elasticity as a result of organic matter decline
• General lack of legumes in rotations
• Record wet summers prior to the 2012 winter crop
• High yields in crop preceding 2012 winter crop
• Summer 2011/12 denitrification events
• Fertiliser N management strategies – quantity and timing
• Dry spring – subsoil finish - moisture and available nitrogen dislocation
Does the 2012 outcome mean that we have the foundations of N nutrition wrong? No, the soil N cycle is still the same, but we need to heed the low protein warnings. These warnings suggest that “set and forget” nitrogen management of the past was a legacy of the fortunate combination of soil organic N reserves and climate and this may need to change. With increasing impact of factors such as declining N reserves and apparent increasing varietal difference in N use, nitrogen management especially for high grain protein may well need more considered in-season management oversight and different N management options for the future.

If you do not want to be concerned by yellow spot in 2013 (including at seedling stages) then:
1. DO NOT sow wheat-on-wheat
2. If you are going to sow wheat-on-wheat consider a late (autumn) stubble burn and/or
3. Select a wheat variety with some level of resistance to yellow spot (note tolerance/resistance to other diseases though).
Primary management decisions for yellow spot need to be made prior to and/or at sowing. Fungicides are a poor last resort for controlling yellow spot as they have reduced efficacy. This IS NOT stripe rust!
