The Fungicide Resistance Action Group (FRAG) produces guidance on pesticide resistance issues. Hosted by AHDB, this information can be used to help protect crops and the long-term efficacy of fungicides.

The AHDB-supported Resistance Action Groups (RAGs) are informal, UK-based groups consisting of experts from the Crop Protection Association (CPA) member companies, other representatives from the agrochemical industry, a range of independent organisations, including public-sector research institutes, and the Chemicals Regulation Directorate (CRD).

Integrated Pest Management (IPM) is based on a diversity of pest management measures (prevention, non-chemical control, best practices for optimizing pesticide efficiency, etc.). These are combined at the farm level to enable reduced reliance on pesticides, and therefore a decrease in the exposure of the environment and people to pesticides.

We deliver transformational projects to drive productivity and boost farming and supply chain businesses. We want the industry to thrive in a rapidly changing world and continue to produce high quality food, maintain our beautiful landscape and leave a legacy for generations to come. 

Crop protection refers to practices and measures employed in agriculture to safeguard crops from both biotic (pests, diseases and weeds) and abiotic (environmental factors) stresses. They key goal of crop production is to maintain crop productivity, health and quality whilst minimising yield losses.

Diseases infect susceptible plant hosts, where environmental conditions favor disease development. Infected crops achieve lower yields and the quality of the produce can also be affected.

Fungicides are a type of agrochemical used specifically to kill fungal pathogens or inhibit the growth of fungi and the spores that they produce. They full under the umbrella of plant protection products (PPPs), also referred to as pesticides, along with other agrochemicals such as herbicides and insecticides that target weeds and insect pests respectively.  Prior to the development of fungicides, there are many historic cases of pathogenic fungi devastating crop yields - one of the most famous being the Irish Potato famine of 1845-52. This was caused by the potato late blight fungal pathogen Phytophthora infestans which today still causes massive losses to agriculture globally, although management by fungicides is now an important component of control.  A wide variety of fungicides exist with various modes of action (MOAs) to effectively control many fungal diseases including mildews, rusts, blights and leaf spots. A threat to modern agriculture is the development and spread of resistance to such fungicides amongst fungal populations.

Antimicrobial resistance (AMR) in agriculture is a pressing global concern that arises when microorganisms, including bacteria, develop resistance to antimicrobial agents such as antibiotics and antifungals commonly used in agricultural practices. This resistance can have far-reaching consequences for both agriculture and public health.
