Ergot (Claviceps purpurea) remains a significant concern for arable growers due to its toxic impact on the food and feed chain.
The presence of ergot alkaloids fungus in grain can pose serious health risks, and as a result, most processors will reject contaminated loads. While post-harvest cleaning can physically remove the visible sclerotia (ergot bodies), it comes at a cost, typically borne by the grower, and is not always fully effective in eliminating the associated toxins.
The challenges of ergot management span the entire crop production cycle.
Tolerance of ergot in seed, a lack of approved agronomic treatments, and wider industry shifts, such as increased adoption of minimum tillage, direct drilling, and the use of wildflower margins, can all contribute to the persistence of ergot, particularly from grass hosts. Unpredictable weather further complicates control efforts.
To address this, Red Tractor has been actively involved in the Ergot Working Group, which is collaborating with AHDB to revise and improve current guidance. This work is now underway, following a decision by the group last year to commission the AHDB to lead the review.
This work is intended to equip the industry with clearer, more practical guidance on how to manage ergot risk effectively. Red Tractor will continue to engage in this process and will share updates as the review progresses.
