How It Works
3336F contains thiophanate-methyl, a systemic fungicide in the FRAC Group 1 class. It interferes with fungal cell division, preventing disease progression and protecting healthy turf from new infections.
Application Guidelines
- Apply at first sign of disease or preventively during high-pressure periods.
- Use sufficient spray volume for uniform coverage.
- For soil-borne diseases, lightly irrigate after application to move product into the root zone.
- Follow labeled rates depending on disease and turf type.
Resistance Management
Do not make more than two consecutive applications before rotating to a fungicide with a different mode of action (FRAC group). Rotating chemistries reduces resistance risk and improves long-term effectiveness.
