Guest Speakers: DPIRD Research Scientist Dr Dustin SevertsonIn this episode of Grains Convo we talk about a serious pest of canola, and all brassica crops, the diamondback moth. 

Diamondback moths lay eggs on canola plants and the emerging larvae feed on plants. In addition to damaging canola crops the diamondback moth is renowned to develop insecticide resistance, so it important that growers apply an integrated pest management strategy if numbers are high.

DPIRD, with investment from GRDC, is working with WA grower groups and surveying all port zones for diamondback moths and larvae activity with manual and automated traps.

In this episode of Grains Convo we speak with DPIRD Research Scientist, Dr Yong Han about gene editing technology and  how it will influence the future of plant breeding in Australia.

Gene editing technology is different to genetic modification. If you have been interested to understand how scientists are developing the next generation of crop varieties with this technology.

This technology is revolutionary and was awarded a Nobel prize in 2020. Dr Han is adopting this technology for crop genetic improvements, that will influence yield, quality and many other agronomist traits.

Guest Speaker: DPIRD Senior Plant Pathologist, Manisha Shankar

Western Australian grains researchers have wrapped up a ground-breaking project resulting in 11 new wheat lines with very high levels of resistance to yellow spot.

In this podcast, DPIRD Senior Plant Pathologist and Project Leader ManishaShankar discusses the project undertaken to get these wheat lines and how they could make future wheat varieties less susceptible to yellow spot.

In Australia, yellow spot is estimated to cause losses totalling $212 million per annum.

The lines developed by the research project have now been delivered to various breeding companies and are crucial genetic stocks for future breeding.

Manisha explains plant genetics and how it relates to disease resistance. She also explains the interests that led her into the exciting field of genetics.

Interviewee: DPIRD Research Scientist, Tom Edwards

Interviewer: Grains Research, Development and Extension Communications Manager, Amber Atkinson

In this episode DPIRD Research Scientist Tom Edwards explains the research he is undertaking in soil management to boost grains productivity.

Tom is assisting with a series of trials to help growers manage soil constraints like acidity, compaction, water repellence and herbicide-resistant weeds.

His focus is on mechanical soil amelioration, which includes common techniques include soil mixing, (e.g. ripping and spading), soil inversion (e.g. mouldboarding or one-way plough) and deep ripping, all of which lead to various degrees of soil mixing, creating a changed soil profile.

Tom explains some of the main barriers to adoption and what he is aiming to achieve in his trials.

In this episode of Grains Convo we discuss oat diseases in WA - particularly Red leather leaf (RLL) and oat leaf rust.

Plant pathologist Geoff Thomas summarises the main oat diseases found by DPIRD when conducting widespread surveillance of WA cereal crops over the past few years.

The presence of RLL in WA was only recently confirmed from three oat samples from Pingelly, Narrogin and Piesseville that were collected in 2021 as part of general disease surveillance. DPIRD is surveying for RLL this season and growers and consultants can submit suspected RLL samples to DPIRD

Plant pathologist Dr Kylie Chambers discusses oat leaf rust and its impact on grain and hay yield and quality and management recommendations – based on 2020 and 2021 trial findings.

In this episode of Grains Convo we focus on blackleg in canola and blackspot in field peas.

You'll learn about the disease risk forecasts, now available on the DPIRD website, for blackleg in canola and blackspot in field peas. Risk forecasts provide a sowing guide to avoid early disease infection in seedling crops. Growers and consultants can subscribe to receive a weekly sms identifying the Blackspot disease risk for their location.

The free app, BlacklegCM, is a tool designed to assist growers and consultants to determine the probability of an economic return from fungicide management for the control of blackleg disease.

BlacklegCM accounts for the major factors that influence blackleg severity. The user can specify factors relating to paddock selection, seasonal conditions, prices and management options so that the output relates to their own cropping circumstance.

In spring 2021 there were widespread areas of bare, or low groundcover, sandy soils in the West Midlands region of WA. This was unusual due to the favourable growing conditions experienced in the previous year. Investigations by DPIRD and the West Midlands Group found that high grasshopper numbers, along with other contributing factors like a false break, over-grazing or a low pasture seed bank resulted in these conditions.

In this podcast DPIRD Research Scientist Geoff Moore discusses the findings from investigations by DPIRD and the West Midlands Group, what growers needs to watch out for in 2022 and how to manage low groundcover.

DPIRD Research Scientist Svetlana Micic advises how to identify and manage sand grasshoppers.

Pre-harvest sprouting (PHS) is a common quality constraint of wheat that can result in downgrading of grain quality upon receival. In WA, the falling number test is conducted at receival sites where suspected pre-harvest sprouting damage has occurred, determined by detection of visually sprouted grains. In this episode DPIRD research scientist Jeremy Curry explains pre harvest sprouting and discusses the research he is doing in this area. Learn about his findings to date and the advice he has for WA growers.

It is easy to focus on understanding and implementing weed control tactics. However, it is also important to consider aspects of weed biology and ecology. Ongoing weed control cannot be successful until we understand how weeds grow and interact with other species, including crops, management practices and the environment.

Join Alex and Catherine to learn more about the valuable new publication, Emerging weeds – seed bank ecology of emerging weeds. By being aware of weedecology, the likely weed-related implications of changing farming practices such as new crops, earlier sowing, or soil amelioration can be understood.

Turnip yellows virus (TuYV, formerly known as beet western yellows virus) is an obligate plant parasite transmitted exclusively by aphids, specifically the Green peach aphid. TuYV systemically infects canola plants and cannot be sprayed-out post-infection like a fungal disease.

DPIRD research scientist Dr Ben Congdon, in collaboration with Cesar Australia, is testing an early warning system for TuYV epidemics in Australian canola crops. By detecting migrating aphids carrying TuYV using yellow sticky traps and a rapid and sensitive RNA detection technique, this system may provide virus risk information to growers that enables proactive TuYV control strategies and prevent widespread TuYV infection and damage in canola crops.

Sclerotinia stem rot is a fungal disease of canola and lupin that can cause significant yield loss. Yield losses can be severe in years of higher moisture and cooler conditions which favours disease development. With foliar fungicide applications not always economical, the decision to spray or not to spray is complex. DPIRD (with co-investment from GRDC) has developed the SclerotiniaCM decision support tool to assist in this process.
