This free fungicide resistance chart also has a timeline for how long fungicide resistance occurs after the introduction of common turf fungicides.

2025 AUSTRALIAN TURF FUNGICIDE RESISTANCE
CHART
Repeated use of fungicides with the same
site of action can result in the development of fungicide-resistant pathogens.
The chart below lists turf registered premix fungicides by their
trade names so you can identify the component fungicides and
their respective mode of action groups. Refer to the Mode of
Action Chart on the Left for more information.
This chart groups fungiicides by their sites of action 1) to maintain greater diversity in fungiicide use and 2) to
rotate among herbicides with different sites of action to delay the development of fungicide resistance. The
Mode of Action (MOA) Group is a classification system developed by the Fungicide Resistance Action
Committee (FRAC).
