Clayton Canyon SC™ – Versatile multi-site fungicide, offering reliability, added efficacy, and the ideal partner choice for disease control in cereals.

Posted on 26 March 2025

Making disease control decisions easier this season with CLAYTON CANYON, a multi-site fungicide which adds flexibility, efficacy and value into your fungicide programme. Offering real versatility at early T1 timings to keep protection levels high, it can be a perfect partner product to use alongside other triazole fungicides or new chemistry in all spray timings. As a multi-site protectant fungicide, it adds to control of Septoria and a range of other cereal diseases, and with an alternative mode of action it is useful in fungicide resistance management strategies and stewardship programmes.

In Velcourt trials conducted in 2024, the addition of CLAYTON CANYON @1.0L resulted in significant yield increases for many T1 treatments tested compared to the same base treatment without folpet. When folpet was added at T1, the highest performing generic treatment in the trials (Clayton Tendril) outyielded the trial standard (AscraXpro) by 0.23 t/ha, highlighting the positive impact of partnering with folpet at this timing for yield gain. CLAYTON CANYON consistently improved yields across treatments by 0.2-0.4 t/ha, in line with other recently conducted industry trials work.
