GRDC Podcast

With water such a valuable commodity nowadays, it’s little wonder that irrigators ask themselves whether they are better off selling their water or using it to grow out a crop. It’s a tough question.

So GRDC last year asked the Irrigated Cropping Council to see if they could come up with some answers.

Blackleg is a common yet economically serious canola disease in Western Australia (WA). While it has the potential to cause severe yield loss, the good news is that it can be successfully managed.

Dr Ravjit Khangura from the Department of Primary Industries and Regional Development (DPIRD) is an expert in this area, and advocates an integrated disease management approach.

Dr Khangura joins Deb Bishop to discuss blackleg management tactics and GRDC resources that are available to help WA growers combat the disease.

Diamondback Moth is an occasional pest of canola, but severe infestations of adults and/or caterpillars can cause up to 80 per cent yield losses in canola and other brassica crops.

This pest can also rapidly develop insecticide resistance and an integrated pest management plan is advised for sustainable control.

A research effort led by CSIRO, with GRDC investment, has developed a modeling tool that could in future years help growers rapidly understand the extent of crop damage following a frost event to aid with timely decision-making post-frost.

The Frost Mapping project is one of a number of projects related to GRDC’s key investment target strategy for frost.

This episode is focussed on the second research component of the Frost Mapping project, assessing frost damage before its visible to the naked eye, using the Electromagnetic spectrum.

This is a collaborative project involving Mick Faulkner, the University of Western Australia, Agriculture Victoria and grain growers, including David Mitchell from Mintaro in South Australia’s north eastern grain growing zone.

The Frost Mapping project is one of a number of projects related to GRDC’s key investment target strategy for frost.

Using a GRDC/RCSN ‘local project’ investment into tactical fungicide use involving a local western region farm adviser is addressing the issue of managing spot form of net blotch (SFNB) in barley crops.

This disease is a R&D priority for the Regional Cropping Solutions Network Kwinana West (RCSN) group and for the GRDC Western Regional Panel. This podcast highlights how local research results are providing solutions for this disease, especially the economics of fungicide use.

Glyphosate resistance is on the rise in Australia’s grain growing regions. With 17 key weed species already identified as resistant, sustainable herbicide practices have never been so important.

In this podcast Andrew Storrie from AGRONOMO discusses what herbicide resistance (or susceptibility) testing options are available to WA growers.

Grain growers in Tasmania could be averaging cereal yields of 7 tonnes per hectare. The top 10 percent of those growers could be doing double that tonnage.

This is a major outcome the Hyper Yielding Cereals project wants to see after 5 years of Research, Development and Extension.

This podcast will take you to Hagley in northern Tasmania where the GRDC has invested in a major trial to lift feed wheat and barley yields, as well as improve grain quality and reduce the need for the island state to import cereals.

Leading the Hyper Yielding Cereals R&D team is Nick Poole from FAR Australia.

Researchers at the Queensland Department of Agriculture and Fisheries are testing the law of unintended consequences – in this case whether wheat varieties that stay greener longer are also prolonging the feeding of aphids on wheat plants.

On this podcast, Entomologist, Melina Miles and her team take us into the tiny world of aphids.
