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.

Best For

• Cool-season lawns (Fescue, Bluegrass, Ryegrass)
• Warm-season lawns (Bermuda, Zoysia, St. Augustine)
• Preventive disease programs
• Curative treatment of active fungal outbreaks
