Protecting Pulse Crops: A Call to Action for Western Australian Growers
Western Australia's pulse growers face a critical decision to safeguard their 2026 harvests. The Department of Primary Industries and Regional Development (DPIRD) is offering a unique opportunity: free seed testing to identify high-risk viruses that threaten yields, seed quality, and profits. But will growers seize this chance?
Here's the catch: The offer is limited, focusing on cucumber mosaic virus (CMV) in lupins or lentils and pea seed-borne mosaic virus (PSbMV). Growers can test up to two 400-gram seed lots for these viruses, which can cause devastating damage. And this is just the tip of the iceberg.
The initiative's benefits are twofold: First, it alerts growers to potential virus risks, empowering them to make informed decisions. Second, the collected data will fuel a national research project, enhancing our understanding of these viruses and their impact on crops.
But here's where it gets controversial: Sowing infected seeds can lead to random infected seedlings within the crop. Aphids, those tiny pests, can then spread the virus to healthy plants, reducing yields and further infecting the harvested seed. It's a silent threat that can go unnoticed until it's too late.
DPIRD trials reveal that CMV and PSbMV can cause yield losses of over 50%, a staggering figure. Even more intriguing, research shows that PSbMV can affect field peas without any visible symptoms, making it a stealthy adversary.
Dr. Congdon emphasizes the importance of sowing clean seed, as managing these viruses post-sowing is nearly impossible. Testing allows growers to assess infection levels and make strategic choices. This project also aims to study virus prevalence and diversity across regions, crops, and seasons, providing valuable insights for future management.
The project's scope is impressive, including research on various viruses and the development of improved management strategies. But the real question is, will growers embrace this opportunity? And what other challenges might they face in the battle against these invisible threats?
For those ready to take action, submitting samples for testing is simple. Growers can email DPIRD's research scientist for a seed testing form, ensuring confidentiality. This small step could be a giant leap in protecting Western Australia's pulse crops.
