Avoiding Buildup of Resistant Fungi
- Most failures are probably not due to fungal resistance to fungicides.
- Fungal resistance is most likely to develop where you over use systemic fungicides and don’t alternate modes of action.
Examples in the PNW on Microdochium Patch: Clearys 3336, Chipco 26GT, and Heritage.
- Pathologists have numerous theories on the best strategies for managing fungicides to avoid resistance.
