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 different modes of action to delay the development

of fungicide resistance.
