By 2030 Asia’s demand for wheat will increase by a further 8 million tonnes and that offers Australia’s wheat industry real opportunities. Speaking at the Perth Grains Research Update the CEO of the Australian Export Grains Innovation Centre, Richard Simonaitis told delegates, Australia is well placed to win a share of the forecast increase in demand.

While the topic for Richard’s Update presentation was ‘A glimpse into the future for the Western Australian Wheat Industry’, the podcast contains information highly relevant to wheat growers and industry stakeholders across Australia.

A new resource is available to help grain growers make proactive integrated pest management (IPM) decisions to control diamondback moth (DBM) in canola. It’s called the DBM best management practice guide, and in this podcast, entomologist Dr Kym Perry from the South Australian Research and Development Institute (SARDI) the research division of Primary Industries and Regions South Australia, explores the contents of this guide.

He covers the key information growers need to know when implementing IPM strategies, including the factors of DBM outbreaks, effective monitoring techniques and taking an economic threshold-based approach to chemical use.

This podcast has been developed as part of the investment, "Supporting the sustainable use of insecticides and local on-farm implementation of IPM strategies in the GRDC southern region”. The investment aims to provide knowledge and skills to growers so they are equipped with a range of appropriate IPM strategies for their situations. It is being delivered by Birchip Cropping Group, cesar, SARDI, C-Qual Agritelligence, and Queensland Department of Agriculture and Fisheries (QDAF). There are also best management practice guides, and accompanying podcasts, available for redlegged earth mite and green peach aphid.

The overuse of insecticides and evolution of resistance in redlegged earth mite (RLEM) is a significant issue for southern and western grain growers. But a new snapshot-style resource is available to help growers make sustainable integrated pest management (IPM) decisions to deal with this pest in canola. It’s called the RLEM best management practice guide, and in this podcast, entomologist Dr Paul Umina talks through the guide in more detail, including factors that influence RLEM numbers in canola and the proactive management strategies.

This podcast has been developed as part of the investment, "Supporting the sustainable use of insecticides and local on-farm implementation of IPM strategies in the GRDC southern region”.

There has been some conjecture in the grains industry as to whether Yellow Leaf Spot is simply a cosmetic disease that has little impact on yield and the contrary view that yield loss can be significant. New research has found that in wet winters the disease does indeed lead to reduced tonnages.

On this podcast, Agriculture Victoria plant pathologist, Grant Hollaway talks about what his research found and also some options for growers who would like to avoid the problem in the first place.

The past can teach us many valuable lessons, particularly when it comes to nature. Scientists around the world are going back in time to capture valuable new traits for modern day chickpeas. Australian scientists are using chickpea varieties collected from the harshest environments to capture strong traits for properties such as increased drought tolerance.

On this podcast, Lars Kamphuis from the Centre for and Disease Management in Perth explains the Australian context of this exciting research.

New research by CSIRO has revealed that grazing crops can add up to $1000 per hectare to a farm’s bottom line. With high livestock prices, dual purpose cropping has many advantages, both direct and indirect, including filling the winter feed gap and allowing extra spring pasture growth.

On this podcast, CSIRO’s Lindsay Bell outlines those benefits.

Understanding the amount of nitrogen already available in the soil prior to developing a nutrient budget will help growers to optimise yield and maximise profit for the season ahead. That is one of the key themes discussed in a new Grain Research and Development Corporation (GRDC) podcast on nutrient budgeting by Cropfacts consultant Harm van Rees, Norton Agronomic director Robert Norton and Agronomy Solutions director Sean Mason.

The podcast discusses research findings arising out of the GRDC investment ‘Using soil and plant testing data to better inform nutrient management and optimise fertiliser investments for grain growers in the southern region’, which is focused on increasing growers’ use of soil and plant testing data to better inform their fertiliser decision-making.
