• We know that ryegrass and other weeds can be beaten by ‘driving down’ the seed bank using a diverse range of tools. Many growers who have been on this program for a decade or more are having a win. It is not easy, but we can win, however, it takes more than herbicides alone....

• Intensive monitoring of soils and crops over a rotation sequence has identified why crops do not achieve their potential yield. • Reviewing paddock performance at the end of the season and using paddock records are essential for sustained improvement in agronomic performance. The average yield gap of wheat and barley over four years of monitoring...
-
• Green on green camera technologies is now used on farms. This will lead to important financial benefits for growers but will also have impacts on farm management. • Growers need to understand the benefits but also the limitations of these new technologies. This is the only way it will bring real benefits....

• Selecting mid-fast canola hybrid varieties with flexible phenology in the Wimmera manages risk and captures great upside when seasonal conditions are favourable. • Fast hybrids have performed well but avoid the temptation to plant these early if an early break eventuates. • Selecting slow developing varieties comes with the added risk of requir...
-
• Proactive disease management can minimise losses associated with root and foliar diseases. • Avoiding highly susceptible varieties where possible provides effective disease control. • Identifying paddocks at risk of root disease prior to sowing using PREDICTA® B testing enables strategies to minimise yield loss to be implemented....
-
• Damaged lentils retain high concentrations of protein and fibre. • Dietary fibres can act as prebiotics which enhance digestive function. • Flour produced from frost damaged lentils can be successfully incorporated into wheat-based food products adding value to the crop and providing many benefits as a novel food alternative for consumers....
-
• Research results from the GRDC Stubbles Initiative and the preceding GRDC Water Use Efficiency (WUE) project have discovered several management challenges in a no-till environment where stubble loads often exceed 8t/ha. • Triazole fungicides give relatively poor control (25%-50%) of yellow leaf spot, Pyrenophora tritici-repentis, in a wheat-on-w...
-
• Forecasting tools for crop pests and beneficials increase confidence in when intervention is or is not needed. • Risk factors associated with the continued spread of redlegged earth mite (RLEM) resistance (besides high pesticide usage) include high winter rainfall, low summer rainfall, low temperature variability (e.g. coastal) and a longer growi...

• After several seasons of growth, the area sown to pulses in Victoria stabilised in 2018 in response to challenging climatic conditions and lower yields in 2017. Unfortunately, 2018 again proved to be challenging in many regions, particularly the Mallee and Wimmera, with extremely dry conditions and very low yields. High prices with faba beans hav...

• The Mallee experienced an above average number of frost days during 2018, where the trial site (12km north west of Ouyen) recorded 37 mornings below 0⁰C between August and October. • Lentils were most susceptible to frost during the flowering and pod filling stage, where temperatures below 0⁰C at canopy height decrease grain yield and quality. • ...
