A national #biosecurity initiative announced by GRDC Chair John Woods at the #GRDCUpdates in Perth today is set to transform the effectiveness and responsiveness of Australia’s grains biosecurity system: bit.ly/3wDMZoH @nswdpi DPIRD Broadacre - WA Grains & Livestock PIRSA DEECA Victoria Department of Agriculture and Fisheries Queensland

In this project - we are applying the latest molecular diagnostic tech to give us deeper and more comprehensive insights into virus and vector risk to grains crops GRDC DPIRD Broadacre - WA Grains & Livestock

GPA+TuYV are most damaging to canola early in the season when virus-carrying GPA migrate from volunteer canola or brassica weeds. Going to spray green bridge out? Try and do it >2 weeks before sowing canola. Monitor crops early! DPIRD Broadacre - WA Grains & Livestock GRDC West

Growers across the southern region are encouraged to eliminate volunteer canola, which is currently widespread, to reduce the risk green peach aphid & turnip yellows virus. 👉 bit.ly/43gmYbj AgCommunicators DPIRD Broadacre - WA Grains & Livestock Macquarie University Agriculture Victoria Marcroft Grains Pathology

Super excited to share our new Plant Biosecurity Bioinformatics pipeline, sangerFlow! biorxiv.org/content/10.110… sangerFlow automates the analysis of the diagnostic PCR Sanger sequencing data and produces a species ID leveraging Nextflow and Singularity containers

New study led by Cesar Australia's Dr. Samantha Ward reveals low-level resistance to sulfoxaflor in green peach aphids across Australia. Read the story here: buff.ly/4dXhIOJ

Reports of aphid infestations have been common. Early virus infections may be responsible for some of the discolouration & mottling symptoms seen in canola & pulse crops. FREE testing for virus diseases is available. Joop van Leur @NSWDPI_AGRONOMY GRDC North

Green peach aphid sightings in New South Wales have farmers on alert. With early canola growth at risk and concerns of a repeat of the 2014 turnip yellow virus outbreaks, decisions on insecticide use are crucial. Read more here: buff.ly/3KwhZe7

🪲GPA-known as vectors of TuYV, have been abundant this season.🧐Inspect your crops for GPA and look for virus symptoms. We can assist with both aphid ID and plant testing services to confirm TuYV presence. Joop van Leur @NSWDPI_AGRONOMY GRDC North GRDC

From 2nd April to 29th May - No green peach aphid detected at any of our monitoring sites. Plenty of other species caught around Northam and Esperance, and cabbage aphid moving out of dual-purpose canola around Kendenup. No TuYV detected yet. GRDC West DPIRD Broadacre - WA Grains & Livestock The UWA Institute of Agriculture

UPDATE - TuYV detected in cabbage aphid at 5 sites on the south-coast. Without GPA the risk is still low but virus is present. Dual-purpose or volunteer canola, and wild radish are likely sources. Keep an eye out for GPA in young spring canola DPIRD Broadacre - WA Grains & Livestock GRDC West GRDC

⚠️Alert for NSW canola growers⚠️ An outbreak of green peach aphid has been reported with an increase risk of turnip yellows virus. Monitor aphid activity, esp. along field edges & correctly ID green peach aphids before spraying. 👉 bit.ly/3yXF2fv Cesar Australia

DPIRD's aphid surveillance program has detected turnip yellows virus in migrating cabbage aphids in southern WA 🔍 Read about other aphid activity in the latest #PestFactsWA newsletter 👉 agric.wa.gov.au/newsletters/pe…

Green peach aphid found around Northam but #TuYV not detected in this region yet. Winter canola still a cabbage aphid factory in the south. Thanks to Amber BC for the GPA spot! DPIRD Broadacre - WA Grains & Livestock GRDC

Inoculating our final trial in a series of trials examining management of green peach aphid and #TuYV in canola - foliar insecticides, seed treatments, host resistance - alone and in combo. Which is most effective? So far - host resistance! GRDC DPIRD Broadacre - WA Grains & Livestock

Contrast in growth across the same canola crop. Healthy & budding prior to flowering whilst TuYV takes hold in affected patches. Green peach aphids have been sprayed with Transform but the damage is done with yield potential unknown in affected areas.

APHID TRAPPING UPDATE 10th JULY - Green peach aphid and/or turnip yellows virus detected at various locations - when both GPA and TuYV is present = disease risk is considered elevated in pre-flowering canola. More info: shorturl.at/OfAWU GRDC GRDC West DPIRD Broadacre - WA Grains & Livestock

We have detected high levels of turnip yellows virus in diseased canola crops in the Geraldton region. Green peach aphid, the vector, was first found in early July and conditions have proven conducive forTuYV spread. Images - Peter Norris. DPIRD Broadacre - WA Grains & Livestock GRDC West GRDC

Turnip yellows virus infection levels in 23 canola crops. Testing done at ~early flowering (between 9th July to 23rd August) because TuYV can have significant seed yield and quality impact when transmission occurs prior to flowering DPIRD Broadacre - WA Grains & Livestock GRDC West #NationalVirusProject
