Clayton offers a wide range of leading fungicides for cereal crops this spring. Achieving good crop growth to maximise yields relies on effective, early control of damaging fungal diseases. Careful planning in terms of product choice for contact and protective fungicides will help growers achieve the best results at key application timings. Our cost-effective products can help put in place the right building blocks for successful disease control.

The benefits of early disease control

Early disease onset in crops varies each season. If cereal crops are not protected at key timings and at early stages of disease development, crop yield potential can be severely impacted.

Many fungicide active ingredients rely on protectant activity and therefore must be applied before disease becomes established. With an expanding range of proven, cost-effective fungicide formulations, Clayton provides valuable choice, flexibility and ideal baseline products for tackling cereal diseases this spring.
