Latest News
New Guidelines:
- Potato late blight: Guidelines for managing fungicides resistance - updated March 2009
- General guideline and list of resistance problems known in the UK - updated January 2009
- Fungicide Resistance Management in Cereals
- Fungicide Resistance in Potato Pathogens; Potato Tuber Diseases
Aims and Objectives
- To gather and interpret information on fungicide resistance and its management and arrive at a United Kingdom (UK) consensus view.
- To promote practical guidance on the status and management of fungicide resistance in the UK.
- To indicate areas where Research and Development are required.
- To provide an interface between industry's Fungicide Resistance Action Committee (FRAC) official bodies and independent research organisations.
- To produce, publish and promote educational material that will assist in the understanding of and reduce the incidence of resistance in plant pathogens.

Reporting Incidences of Fungicide Resistance
FRAG are collating reports of fungicide resistance in the UK. This is both to monitor the extent of know resistance problems and to detect possible new occurrences.
If you are aware of a possible case of fungicide resistance please print out and complete one of the forms available below.
Please remember that there may be other reasons why fungicides fail to control a disease to the extent expected. These include using too low a dose, applying the fungicide at the wrong time and adverse weather conditions during or after application. Please consider whether factors such as these may account for the poor performance of a fungicide before making a report.
Please print out and complete page 1 of one of the forms below before returning to the address at the end of the form.
Guidelines and other Publications
Fungicide Resistance Leaflet
General guideline and list of resistance problems known in the UK includes
- Guidance on strategies against resistance
- Glossary of resistance terms
- List of known and potential resistance problems in the UK
- Interactive lists of fungicide groups and market leading products available on different crops Acrobat pdf version / Online version (includes interactive database of fungicide groups
Guidelines for Preventing and Managing Resistance in Cereal Pathogens
- The new updated 2008 version of the Fungicides Resistance Management in Cereals is now available
Older information still available
Information and guidance for Septoria tritici resistance management in cereals (Jan 2004)
Original Jan 2003 Statement on resistance in Septoria to QoI fungicides
- Further guidance on wheat disease management and fungicide strategies is available from the HGCA.
Possible resistance in Tan Spot:
Although sporadic in the UK, Tan spot (Pyrenophora tritici-repentis) has been known to cause occasional serious problems in wheat. Although no resistance has been found in the UK, the genes conferring resistance to QoI fungicides have been identified elsewhere in Europe. FRAG-UK will keep the issue under review, in the meantime further information and advice may be available from the FRAC QoI working group.

Latest late blight situation
There have been recent changes in the proportions of different strains of Potato Blight present in the UK which appear to be linked to an increase in resistance to phenylamides. While the current levels of phenylamide resistance are high, they are not unprecedented. It remains vital that phenylamides are used as part of a resistance management strategy and due to the current situation the number of sprays should be restricted. Refer to the manufacturer for the latest advice.
