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

Growers, keep an eye out for green peach aphid (GPA) in canola this season! Even if seed is treated with insecticide, regular monitoring is required, especially if foliar sprays are needed to manage GPA & turnip yellows virus. agric.wa.gov.au/newsletters/pe… #PestFactsWA GRDC West

Seed treatments cannot be solely relied upon to control green peach aphid and turnip yellows virus. Foliar insecticide may be required. Regular monitoring of plants, esp. from emergence until the 5-leaf stage, is crucial to effective foliar spray. DPIRD Broadacre - WA Grains & Livestock GRDC

🪲Aphids have been active in canola this autumn. Despite the wet season in NNSW, warm conditions are driving aphid spread, and rain won't suppress their numbers. Monitor paddocks closely and act early! Don’t wait for purple leaves or signs of TuYV. NSW Agronomy GRDC North

Green peach aphid (GPA) detected on traps near Amelup and turnip yellows virus (TuYV) detected in non-GPA aphids caught at South Stirlings. Found nothing in crops yet but won't be long DPIRD Broadacre - WA Grains & Livestock GRDC West Latest TuYV management research - shorturl.at/GgR1N

We're monitoring green peach aphids (GPA) & testing for turnip yellows virus (TuYV) in canola from April to Aug 2025. After the #PestFactsWA article was published, GPA was found at Amelup & TuYV was detected in non-GPA aphids at South Stirlings. GRDC West dpird.wa.gov.au/siteassets/doc…

First detection of Green peach aphid in 3 leaf canola crop near York. <10% plants infested. Continuing to monitor with suction, sticky and pan traps. #virusproject DPIRD Broadacre - WA Grains & Livestock GRDC West GRDC

Canola aphid & virus update at 29 May: Green peach aphid (GPA) found in canola near York - no Turnip yellows virus (TuYV) detected. GPA also trapped near Amelup (not in crop), also TuYV-negative. TuYV detected in trapped non-GPA aphids at South Stirlings. dpird.wa.gov.au/siteassets/doc…

🎧PODCAST: Aphids & viruses in broadleaf crops🎧 We talk to NSW DPIRD's aphid & virus experts, Joop van Leur, Zorica Duric & Solomon Maina on: -Viruses: the basics & why they mutate & how they are transmitted. -Aphids: which ones are an issue to us in winter cropping.

Green peach aphid and virus update 26 June Low level GPA infestations at Amelup, Cranbrook, Kendenup. No Turnip yellows virus detected in aphids or crops. GPA also found near Tenterden, Albany, York, Northam, Cunderdin, Meckering. #PestFactsWA GRDC West dpird.wa.gov.au/siteassets/doc…

I'd like to go on the record to say the Mukinbudin Hotel is WA's best pub. Great parmi, local beer made with local grains, chatty staff, fun vibe. 10/10 no notes.

And you may even have your Farmers Lager or Sump Oil Stout poured by the Dandanning Brewer himself!
