Bayer has received regulatory authorisation for Plaxium, its first three-way formulation fungicide containing Iblon (isoflucypram). The news means Plaxium will be available to growers for use across a range of winter and spring sown cereals this season.

In a mixture with fluopyram and prothioconazole, Plaxium offers robust broad-spectrum activity in the convenience of a co-formulation.

“Plaxium is the latest fungicide from Bayer to contain Iblon, the proven and highly effective active substance that has shown dependable broad-spectrum activity against the principal foliar threats of cereal crops,” Greg Hanna, Fungicide Market Development for Bayer, says.

“Following the testing 2024 season, Iblon, commercially available as Vimoy, has earned the trust of growers and advisers delivering reliable control of Septoria, yellow and brown rust among other disease threats. Plaxium builds on this trusted performance with the simplicity and convenience of an emulsifiable concentrate formulation containing fluopyram and prothioconazole,” he adds.

Plaxium can be applied once per season to wheat, barley, oats, rye, triticale and spelt up to the start of flowering (growth stage 61) at a maximum rate of 1.5 Litres/hectare meaning growers have the flexibility to apply at either the T1 or T2 timing depending on the seasonal disease pressure and other modes of action used in the programme.

“Iblon has shown itself to be an effective fungicide across multiple disease targets and application timings. In Plaxium, this flexibility has been retained meaning growers, and their agronomists can choose to position Iblon at the timing that best meets their objectives,” Mr Hanna says.
