Penflufen 13.28% w/w + Trifloxystrobin 13.28% w/w FS – Seed Treatment Fungicide (Technical Guide)
Penflufen + Trifloxystrobin FS is a dual-active seed treatment fungicide designed to protect the seed and young seedlings from early-stage fungal risks (as per label). Because it is an FS (flowable concentrate for seed treatment), it is meant to be applied on seed before sowing — not as a foliar spray.
Product Snapshot
- Active ingredients: Penflufen 13.28% w/w + Trifloxystrobin 13.28% w/w
- Formulation: FS (Flowable concentrate for seed treatment)
- Use: Seed treatment for early protection (crop/disease as per label)
Why This Combination is Used
In seed treatment planning, the goal is simple: protect the seed during germination and help seedlings establish evenly. This combination is commonly positioned where farmers want a wider safety net because it brings two different modes of action together (useful for resistance planning and broader protection, label-dependent).
How It Works
- Penflufen (SDHI group): works on fungal respiration (energy system) to slow down fungal growth.
- Trifloxystrobin (QoI group): supports protection by interfering with fungal development and spread.
Because these are two different groups, the mix is often chosen for early-stage protection programs where timing is critical.
Where It Fits Best
- Before sowing: seed is treated and then sown as per normal practice
- Early protection window: helps reduce the risk from seed/soil-borne fungal issues during germination and early growth (label-based)
- Not for foliar spray: do not use this FS product as a leaf spray unless the label specifically says so
How to Apply
Always follow the brand label for dose and slurry volume. In general, good seed treatment practice looks like this:
- Use clean, dust-free seed (better coating and better results).
- Prepare a slurry as per label directions (product + water, if label recommends).
- Apply evenly to the seed and mix until all seeds are uniformly coated.
- Shade-dry treated seed as per label instructions before sowing.
Important Handling & Storage Tips
- Keep treated seed away from food and animal feed.
- Do not wash treated seed in ponds/drains; dispose rinse water safely as per local guidance.
- Store product in original container, tightly closed, away from direct sunlight and moisture.
Compatibility
- Avoid random mixing with other seed treatment chemicals unless the label supports it.
- If using multiple seed treatment inputs, follow a proper sequence and do a small trial batch first.
FAQs
Is this a spray fungicide?
No. FS formulation is typically meant for seed treatment. Use only as directed on the label.
Will one dose fit every crop?
Dose and method vary by crop and label approval. Follow the exact label for your crop.
