2020 Fungicide Classification Chart - Take Action

1 Fungicide CLASSIFICATIONR epeated use of fungicides with the same mode of Action can result in the selection of Fungicide -resistant strains of plant Action is endorsed by the following organizations:For more information and links to additional resources, visit PREMIXThis section lists premix fungicides by their trade names so you can identify the premix s component fungicides and their respective mode of Action groups. Refer to the Mode of Action section on the left for more information. by MODE OF Action (MOA)This section groups fungicides 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 different modes of Action to delay the development of Fungicide CODEMODE OF ACTIONCHEMICAL FAMILYACTIVE INGREDIENTPRODUCT EXAMPLES (Trade Name)MITOSIS DISRUPTERS1 MBC (methyl benzimidazole carbamates)B1: -tubuline assembly in mitosisThiophanatesthiophanate-methylTop sin, multiple generics and component in premixCELL MEMBRANE DISRUPTERS3 DMI (demethylation inhibitors)/ triazolesG1.

6 Always read and follow the label directions. 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.
