Fungicide performance in cereals and oilseed rape

Our fungicide performance work provides high-quality, independent information on the efficacy of fungicides against key diseases in wheat, barley and oilseed rape.

Why is fungicide efficacy data important?

Knowledge of the potential power of an active ingredient (or product) is essential in disease management. First and foremost, it will help you gauge the potential return on your spray investments. Critically, it can be used to develop effective fungicide programmes that balance the need to control disease with the need to protect chemistry from fungicide resistance.

How to use fungicide performance information

Integrated pest management (IPM) is at the heart of disease management. A well-designed rotation (to minimise disease pressure) and an appropriate variety (to resist the main diseases present) will lay a solid foundation and reduce the requirement for chemistry. Where sprays are necessary, our efficacy results can be used to help build fungicide programmes – based on mixtures of active ingredients and products – appropriate to the local disease-threat profile and in keeping with best practice anti-resistance guidelines.

About our fungicide performance trials

Fungicide performance information has been generated for many years – wheat since 1994, barley since 2002 and oilseed rape since 2006. Trials are located in areas most likely to produce high pressure for the target disease(s). Varieties that are highly susceptible to the target disease(s) are grown. Generally, when more fungicide is applied, less disease will be present in a crop. The visible disease present at a range of doses can be shown as a dose-response graph (see example). Curves are published for ‘protectant’ and ‘eradicant’ situations, where applicable.
