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.

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.

In this episode of Grains Convo we talk about frost, which in WA refers to an event when the screen temperature at a local weather station falls below 2°C.

Dr Brenton Leske discusses the impact frost damage can have on crops, how to diagnose frost damage, options available for frosted crops and how growers can minimise frost risk before sowing next season. 

DPIRD, with investment from GRDC, is leading a frost research project exploring the management of ice nucleating bacteria in wheat, barley and canola. This work will explore the use of bactericides and cryoprotectants to inhibit the ice nucleation process on plants and reduce frost damage.

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 podcast, DPIRD research scientist Svetlana Micic discusses how to identify APLs and native grasshoppers, why it’s important to correctly distinguish the two and the best control methods for these pests.

For more information refer to DPIRD’s Australian plague locust page.

DPIRD (with co-investment from GRDC and other funding bodies) conducts invertebrate trapping surveillance each year to monitor the potential risk of destructive pests to WA crops. One of pests surveyed is the native budworm (Helicoverpa punctigera).

DPIRD carries out both manual and automated pheromone native budworm trapping in WA each year. In this podcast. we focus on the manual pheromone moth trapping program and the benefits it provides to the WA grains industry.

For more information refer to DPIRD’s Native budworm moth trapping in WA page.

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. 

For more information refer to DPIRD’s Turnip yellows virus early warning system page.

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.

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.

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.
