Green peach aphids carrying turnip yellows virus (TuYV) detected in Kwinana port zones; TuYV also found in Albany. Growers should monitor canola crops closely.

Will TuYV-resistant canola varieties provide an economic benefit in an epidemic? Inoculating 10 canola varieties with multiple TuYV strains to answer this. We need non-insecticide tools ASAP due to resistance in the green peach aphid @theGRDC @DPIRDbroadacre .

[Ben Congdon @bcong11]

Our GPA/TuYV monitoring continues in 2026, supported by @theGRDC - if you find GPA infesting canola during the early growth stages, get in touch and we will test for virus.

We're monitoring green peach aphid (GPA) & testing aphids for turnip yellows virus (TuYV) across the WA grainbelt. GPA found at Northam (TuYV‑negative) & Dalyup (testing underway). TuYV detected in another aphid species at Woogenellup #PestFactsWA

[PestFactsSA @PestFactsSARDI]

PestFacts SA team has received reports of green peach aphid activity across several regions. With early-sown canola, now’s the time to keep a close eye on crops and watch for Turnip yellows virus symptoms. Please monitor paddocks and share any observations with our team.

[Field Crop Diseases Victoria @VicCropDiseases]

Aphids are being reported as crops are sown in western Victoria. While aphids don’t automatically mean virus, higher numbers increase the risk of TuYV in canola, particularly early. As part of monitoring, we are testing samples to check for potential virus.

A great day out yesterday with our local grower group! Canola virology, wheat and barley varieties, oats cropping challenge, new hervidice option in cereals and Lupins, alternative knockdown strategies and fertility legumes! Thanks to everyone that contributed!

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.

🎧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.
-Insecticide resistance.
-Management options.

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.

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 @DPIRDbroadacre @GRDCWest @theGRDC

[DPIRD Broadacre - WA Grains & Livestock @DPIRDbroadacre]

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. @GRDCWest

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 @DPIRDbroadacre @GRDCWest Latest TuYV management research - https://t.co/ZFHaAPYYgn

[Zorica Duric @ZoricaDuric]

🪲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.

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.

[Ben Congdon @bcong11]

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.
