Fungicides have become an integral part of efficient food production. The loss of a fungicide to agriculture through resistance is a problem that affects us all. FRAC works to prolong the effectiveness of fungicides liable to encounter resistance problems and to limit crop losses should resistance occur.
The FRAC Mode of Action (MoA) classification provides growers, advisors, extension staff, consultants and crop protection professionals with a guide to the selection of fungicides for use in an effective and sustainable fungicide resistance management strategy.
The following table lists commercial fungicides, mainly for use in plant protection, according to their mode of action and resistance risk. The most important bactericides are also included. Grouping is considering the biochemical mode of action, but a main driver is to identify cross- resistance patterns between chemistries.
Fungicides are classified according to their mode of action, or numeric FRAC code. The list of FRAC codes was developed by the Fungicide Resistance Action Committee and is a technical classification of fungicide modes of action according to scientific data.
This guide addresses management of pesticide resistance and describes the Fungicide Resistance Action Committee’s (FRAC) classification of fungicides and bactericides registered for agricultural and non-agricultural use in Florida by their modes of action.
Take Action Fungicide Classification Chart. Repeated use of fungicides with the same mode of action can result in the selection of fungicide-resistant strains of plant pathogens. This chart groups fungicides and fungicide premixes by their mode of action to assist in the selection of fungicides 1) to maintain greater diversity in fungicide use and 2) to rotate among effective fungicides with.
This effect is very quick and has not been observed with other Oomycete fungicides. Interacts with key steps of fungus life cycle. Strong and quick effect on zoospores having curative and anti-sporulant activity. Fungicide Resistance Action Committee (FRAC) Classification No.Fluopicolide 43 (low risk resistance not known); Fosetyl 33.
Modes of action are colour-coded according to the physiological functions affected. This informs the symptomology, speed of action and other properties of the actives therein and not for any resistance management purpose. Base rotations for resistance management on the mode of action number only.
FRAC - Fungicide Resistance Action Committee FRAC is a Specialist Technical Group of CropLife International FRAC Code: Numbers and letters are used to distinguish the fungicide groups according to their cross resistance behavior. The numbers were assigned according to the time of product introduction to the market.
Monceren (pencycuron) is a non-systemic, protective fungicide with long lasting activity. The ingredient is characterized by specific activity against Rhizoctonia Solani.When used as a seed treatment, the product exhibits excellent efficacy against potato black scurf disease.

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).
Effective insecticide resistance management (IRM) is essential if the utility of current and future insecticides is to be preserved. Established in 1984, the Insecticide Resistance Action Committee.
The following table lists commercial fungicides according to their mode of action and resistance risk. The most important bactericides are also included. The Table headings are defined as: MOA Code Different letters (A to I, with added numbers) are used to distinguish fungicide groups according to their biochemical mode of action (MOA) in the biosynthetic pathways of plant pathogens. The.
Fungicide Resistance Action Committee (FRAC) Classification No. 33 (unknown) FEATURES As a result of its complex mode of action, there have been no confirmed cases of fungal resistance development to Aliette under practical use conditions, despite the intensive use of this active ingredient since its introduction in 1978.In 2008, CropLife Australia completely revised Australia’s fungicide activity grouping system to bring it into line with the international Fungicide Resistance Action Committee (FRAC) activity group classification system. This was the first major revision of the Australian classification system since its introduction several years ago. Activity group codes have now been changed from letters.Folicur acts as a systemic fungicide. Demethylase inhibitors (DMI) - interfere in the process of building the structure of the fungal cell wall. Finally inhibit the reproduction and further growth of the fungus. Fungicide Resistance Action Committee (FRAC) Classification No. 3.
