WWW.MSSOY.ORG Y MSPB WEBSITE WITH UP-TO-DATE SOYBEAN PRODUCTION INFORMATION USE FUNGICIDE CLASSIFICATION CHART TO SELECT MODE OF ACTION The repeated use of fungicides with the same with differing modes of action will maintain mode of action will hasten the selection for diversity in fungicide use and delay the fungicide resistance in plant pathogenic fungi. development of projected fungicide resistance. Conversely, selection of efficacious fungicides The information in the following chart will aid in this process. FUNGICIDE CLASSIFICATION Repeated use of fungicides with the same mode of action can result in the selection of fungicide-resistant strains of plant pathogens. by PREMIX This section lists premix fungicides by their trade by MODE OF ACTION (MOA) names so you can identify the premix’s component This section groups fungicides by their mode of action to assist in the selection of fungicides 1) to maintain greater fungicides and their respective mode of action groups. diversity in fungicide use and 2) to rotate among effective fungicides with different modes of action to delay the development Refer to the Mode of Action section on the left of fungicide resistance. for more information.
