Cereal disease

Cost-effective fungicide planning for individual field, variety and weather risks

Adaptive Disease Management (ADM) is a new initiative being developed by Syngenta. Drawing on combined experience of how varieties behave, and how fungicides interact, it is based on the principle of using known disease risk factors to plan a fungicide programme at the start of the season, and adapting this to evolving disease risks as the season unfolds.

Winter Wheat Fungicide Strategy

Adopt a preventative approach

"With reduced sensitivity to triazole fungicides, ‘curing’ Septoria tritici successfully can no longer be relied on. Similarly, the appearance of new yellow rust races has made this disease more unpredictable. Disease can be quietly gaining a foothold and impacting yield potential even before symptoms become visible. Fungicides, in general, give better results if applied preventatively."

T0 fungicide strategy

An effective T0 provides a sound foundation to protect against key cereal diseases and any delays when spraying your T1. In consultation with your agronomist, use the decision tree below to help decide on an effective T0 strategy for your crop.

T1 fungicide strategy

A timely and persistant T1 spray is essential for staying on the front foot against disease, reducing the likelihood of entering into a curative T2 situation. Use the principles from the brochure to plan your fungicide strategy based on your location, drilling dates and varieties, then monitor disease levels and weather forecast and adapt your strategy based on risk. At Innovation Centres across the UK, Syngenta are tailoring fungicide programmes to varieties to get the best disease control and return on investment. They are also comparing a ‘programmed’ approach to adapting the programmes in-season based on the current disease levels and forecast weather.

T2 fungicide strategy

T2 remains the most important fungicide timing in winter wheat, protecting the flag leaf, which contributes most yield. A persistent product is required to provide long-lasting protection against Septoria tritici and rusts. In 2017, we launched our new SDHI ELATUS™ ERA, which delivers powerful, long-lasting disease control; consistent performance across years, regions, conditions; and complete leaf protection. This makes it a perfect fit at the T2 timing.

Winter Barley Fungicide Strategy

With barley acreage increasing in recent years, it is important to ensure maximum finanical contribution to the rotation. Barley varieties (both conventional and hybrid) have historically been treated the same when it comes to fungicides, however, just like wheat, varieties vary enormously in their susceptibility to different pathogens, so need treating accordingly.
