Clayton Tendril™ – High efficacy, dual active co-formulation for control of a broad range of diseases in cereals.

Posted on 26 March 2025

Making disease control decisions easier this season with CLAYTON TENDRIL, a robust, dual-formulation fungicide designed to add real value and very high disease control efficacy into your fungicide programme.

With outright yield in mind, CLAYTON TENDRIL was the highest-performing generic treatment at T1 across Velcourt trials conducted for Clayton in 2024. When boosted with multisite folpet added, its performance improved even further, and outyielded newer chemistry (AscraXpro®) used as the trial standard by 0.23 t/ha at T1, with exceptional product performance. With a broad disease control spectrum, it also has good versatility and is a perfect partner product alongside other fungicides at all spray timings.
