Grain drying and aeration to manage wet grain... Glyphosate is widely used for fallow weed control, particularly on farms using reduced tillage practices... Computer simulations, using a glyphosate resistance model developed by the WAHRI group at UWA, predicted that the probability for ryegrass to develop resistance increased from 0% for conventional wheat system using glyphosate once in fallow to 82% for zero tillage systems with RR crops and greater use of glyphosate...

Biopesticides offer an innovative approach to the management of pests in farming systems using formulated microbial agents as the active ingredient... Microbes that have been used in this approach include fungi, bacteria, viruses and nematodes... From initial surveys, a number of species of Trichoderma not previously recorded from Australia have been identified and their interaction with the organism responsible for crown rot and RLN are being evaluated in laboratory and glasshouse trials...

In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... Delaying any action that has the potential to cease grain fill will see more seeds achieve their maximum size and improve yield... In summary there was no 'concerning' level of seed loss observed at any trial or timing, correlating well with the yield data...
