A new web-based service has been launched to help wheat growers and agronomists stay a step ahead of unpredictable yellow rust outbreaks.
Rust locator 2021 – available at www.syngenta.co.uk/rust-locator-2021 – uses an interactive map to record the locations of yellow rust infections. It highlights the variety affected, its yellow rust resistance rating and drilling date.
Having a regional picture of where infections are appearing gives growers and agronomists added information to help head off outbreaks before they become more damaging, says Syngenta disease control specialist David Ranner (left).
“Information for Rust Locator 2021 is provided by Syngenta field staff. But we’re also encouraging growers and agronomists around the country to submit their own yellow rust sightings, with a chance to win a branded Elatus Era tube scarf for those who do.”
Yellow rust can cause yield losses of up to 50%. Mr Ranner says by having more people uploading ‘eyes-on-the-ground’ sightings, Syngenta wants Rust Locator 2021 to be for everyone’s benefit – helping protect yields.
“Like Septoria tritici, it is a disease that is better prevented, rather than trying to cure it once established. But we have seen over recent years how quickly infections can escalate, and how quickly variety resistance can decline.”
Many varieties don’t have juvenile plant resistance to yellow rust, and adult plant resistance may not take effect until the middle of the season, says Mr Ranner.
“Having an early warning that yellow rust is active underlines the need to manage it appropriately in your own crops.”
