Ep 67Tips On Monitoring For Insects In Early Season Canola
Monitoring a crop is an integral part of a growers integrated pest management (IPM) strategy. Not only does it reveal if any damage is occurring, it also helps in determining pest and beneficial presence and abundance. In this podcast, agronomist Phil Bowden explores these insect monitoring methods in detail, to help growers and advisors make an informed risk assessment and to decide if chemical control is warranted. It’s also detailed in the publication Insect Pests Of Establishing Canola In NSW guide developed by cesar (developer of Pestfacts) and the GRDC.

Ep 62Mechanical Weeder Marks A New Era In Tactical Tillage
Managing herbicide resistant weeds has become a major concern for grain growers, especially in the northern region which has the highest number of glyphosate resistant weed species. These are mainly summer weed species. It was for this reason that GRDC invested in the tactical tillage project and called for a non-chemical means of weed control for use in an integrated weed management system. Answering the call, the University of Western Australia proposed it would engineer a machine that could see weeds and chip them out of the soil.

Ep 50Soil Compaction
Soil is made up of organic and mineral particles and in between these particles are tiny air pockets containing water, soil microbes and fauna. These are essential components for healthy soil and root and crop development. When soil is compacted, the air pockets are squeezed out, compressing the particles closer together making it firmer and more difficult to penetrate. This in turn creates a hostile environment for roots and soil fauna. In this podcast, Wayne Parker, from Western Australia’s Department of Primary Industries and Regional Development and Soil Compaction project leader, talks to Lucinda Jose about the causes of soil compaction and the outcomes from the Soil Constraints West project that growers can adopt to improve their soils.

Ep 36AEGIC - Indonesian Market
Indonesia is, by far, Australia’s biggest single wheat customer. Each year, on average, Indonesia buys 4.2 million tonnes of Australian wheat, worth 1.2 billion dollars. That’s nearly one quarter of all Australian wheat exports. But the threat from low-cost wheat producers, such as Russia and Ukraine – as well as ongoing competition from premium suppliers like Canada and the US – is putting the squeeze on Australian exports to Indonesia. AEGIC, the Australian Export Grains Innovation Centre, is an initiative of GRDC and the WA State Government that exists to increase the value of Australian grain. In this podcast AEGIC CEO Richard Simonaitis talks about the opportunities and challenges facing Australian wheat exports to Indonesia.

Ep 34Optimising weed control with crop row spacing
As a form of weed control in crops reducing row spacing can have a significant impact on weed populations. By reducing crop row spacing the biomass of the weed are reduced but what’s even more important is weed seed numbers are dramatically reduced. These were key messages delivered to grain growers at a Weedsmart conference where Paul McIntosh from the Australian Herbicide Resistance Initiative was a speaker. Also addressing the growers was a farmer from NSW who told of his experience with overcoming a serious weed issue on his property by reducing crop row spacing. Chris Roche and Paul McIntosh pass on their experiences in this podcast.

Ep 33Crop Establishment - WA
Changing weather patterns mean WA growers are often attempting to sow and get crops established in a warming and dry period. Although, there is often a reasonable level of subsoil moisture from summer rains, which are more common than in the past, to help boost establishment if accessed by roots. Geraldton and Kwinana East port zone growers are particularly interested in examining the factors that could be impacting on crop emergence. Most of these involve deeper seed placement for access to subsoil moisture, although crops vary in their ability to handle deeper sowing. GRDC has invested in a case study/booklet project aiming to provide an overview of the latest research into crop establishment for these regions - as well as examples of the successful management practices/tactics being used by growers in the regions. Seeing what others are doing should help growers to make informed decisions to achieve improved crop germination and establishment in a drying soil profile, lessening the risk of crop failure and reduced returns.

Ep 31Soil Amelioration - WA
WA’s sand plain soils feature multiple constraints including water repellence, acidity and compaction, all focus points of GRDC’s $33-million-dollar investment in the Soil Constraints West Project. Soil constraints result in lost grain production worth more than $4 billion annually, just in WA. A key project outcome is that growers should consider treating multiple constraints over smaller areas, rather than working on one constraint at a time. The 'ranking options for soil amendments' (ROSA) tool provides a cost-effectiveness ranking of soil amendment options to address one or more soil constraints within a farm business.

Ep 32Soil Constraints - WA
Soil constraints are reducing grain grower profitability in Western Australia. Soil compaction, low pH and water repellence are estimated to cost the state’s grains industry a billion dollars annually in lost productivity. That is why the GRDC invested in a multi-organisation 5 year R&D program called the Soil Constraints West Initiative. Now in its final year and with up to $33 million invested, changes are happening on farm. Chris Gazey from the Department of Primary Industries and Regional Development is Soils and Nutrition portfolio manager with the Department and oversees the Soil Constraints West projects.

Ep 25Lifting High Rainfall Zone Cereal Yields
Despite having a better climate for grain production than most of mainland Australia, the average cereal yield in Tasmania is still considered to be well below its potential. In this podcast you’ll hear from GRDC’s MD Dr Steve Jefferies talk about two GRDC investments that are working to address this challenge, to help Tasmanian, and high rainfall zone cereal growers on the mainland, close the yield gap and develop new fungicide management strategies. Both areas of research are part of The Hyper Yielding Cereals project and the project’s annual field day at Hagley in northern Tasmania attracted grain growers from as far away as South Australia’s York Peninsular. GRDC’s Managing Director, Dr Steve Jefferies, was at the field day.

Ep 23Weed Management Via Crop Competition
Home gardeners know the benefits of mulch in suppressing weeds, but researchers are also encouraging broadacre grain producers to deprive weeds of sunlight and space and take the pressure off herbicides as the ‘heavy lifters’ of in-crop weed control. While defeating weeds through crop competition isn’t new, Queensland trials have shown that crop density and narrow row spacing have significantly suppressed the prevalent weeds common sowthistle and fleabane in the northern region. The Queensland Department of Agriculture and Fisheries (QDAF) and the University of Queensland (UQ) are currently testing other non-chemical controls such as varietal differences and fertiliser placement for their impact on weed growth and seed production. QDAF project leader Dr Michael Widderick says narrow row spacing has so far shown the clearest benefit in limiting weeds. The tactic suppressed sowthistle and fleabane quite dramatically, but in trials testing control of feathertop Rhodes grass and awnless barnyard grass, the feathertop was quick growing and competed very well against sorghum and mung beans which didn’t suppress it as much as barnyard grass, which isn’t as robust a plant. Both awnless barnyard grass and common sowthistle no have glyphosate resistant populations and sowthistle is becoming an all year round weed issue. The trials showed that: Growing a competitive crop can significantly reduce weed numbers, biomass and seed production in crop while providing increases in grain yield. Growing faba beans and chickpea at a narrow row spacing of 25cm and a high plant density of 70 and 80 plants/m2 respectively significantly reduced sowthistle biomass and seed production while increasing crop yield. Growing wheat at narrow row spacing of 25cm and a high density of 120 plants/m2 significantly reduced awnless barnyard grass density, biomass and seed production while increasing crop yield. Narrow row spacing (25cm) in mung bean and soybean can reduce weed growth and increased crop yield. The critical time of weed removal in mung bean and soybean occurs at later stages of crop growth in narrow (25cm) compared to wide rows (75cm). Michael says these key weeds are increasingly emerging later and affecting winter crops at a growth stage when residual chemistries are no longer persistent in the soil and when in‐crop herbicides are either unavailable or can no longer be applied. But by purposefully using crop competition alongside in-crop residual and knockdown herbicides, producers can delay herbicide resistance and limit future weed populations by reducing seed set.

Ep 22Root Lesion Nematodes - Kirsty Owen
Can you explain the difference between crop varieties that are tolerant, resistant and susceptible to a particular pest? Researcher Kirsty Owen from the University of Southern Queensland (USQ) says knowing the difference is critical for producers responding to one of the northern wheat industry’s thorniest problems. The root lesion nematode, Pratylenchus thornei reduces the ability of crop roots to take up water and nutrients, leaving a sickly plant with yellowing lower leaves and poor tillering. Populations build in susceptible crops, can survive fallow periods and have the ability to carry over between cropping seasons, and there are no registered chemical control methods. Tolerance is the ability of a plant to produce good yields in the presence of P. thornei and its opposite is intolerance, while resistance is the ability of the plant to prevent nematode reproduction. Its opposite is susceptibility. Kirsty says crop varieties may be tolerant but susceptible, that is, they produce good yields but allow the nematode to increase in population. The ideal combinations for management of P. thornei are varieties that are both tolerant and resistant. In USQ’s study of chickpeas, wheat and the build-up and decline of P. thornei in the farming system, researchers found that while chickpea varieties may not suffer yield loss, the crop’s tolerance may lead to a build-up of nematodes that affects the following crop. When P. thornei was present in paddocks at damaging populations (greater than 2/g soil), management relied on growing tolerant crop varieties that don’t suffer yield loss and increasing the number of resistant crops in the cropping sequence to reduce populations. Trials showed that: Chickpeas generally have a good level of tolerance to P. thornei but because most varieties are susceptible, populations of the nematode will increase to attack future crops The tolerance of a wheat variety and the populations of P. thornei at the time of planting will determine the degree of yield loss at the end of the season Intolerant wheat varieties should be avoided when P. thornei populations are at damaging levels, but even moderately tolerant varieties may suffer yield loss. Growers and agronomists can learn how to sample for root lesion nematodes and interpret the results by taking part in PreDicta®B courses run by SARDI; download an app that has ratings for resistance; use the NVT site comparison tool to find tolerance ratings; and tap into their local crop variety guides for more information.

Ep 20ROSA
According to WA’s Department of Primary Industries and Regional Development that estimate of $4.3 Billion in lost production is nearly equal to half the value of the state’s annual grain production, so soil constraint issues are significant. The type of constraints common to the West include water repellency, acidity, subsoil compaction and soil structure decline and the Grains Research & Development Corporation has invested in the development of an analytical tool called ROSA. ROSA stands for Ranking Options for Soil Amelioration and its purpose is to help grain growers rank their soils and prioritise soil amelioration options.

Ep 19RWA & Green Bridge Surveillance
To aid Russian Wheat Aphid management planning and development of cultural controls, there is a need to know what role green bridges play in supporting RWA populations. This information will be used to develop predictive models that will estimate seasonal aphid risk within each affected region. Findings by cesar and SARDI will enable researchers to better inform advisers and grain growers about how to best manage this new pest. Additionally, determining what beneficial insects are best placed to manage RWA is another big question that will be investigated.
