Secure your rice harvest with Fiesta® Forte by FMC Corporation, the advanced pre-emergent herbicide designed for total weed control.
Rice farming in India faces constant challenges from stubborn weeds. Fiesta® Forte helps you win this battle using a sophisticated dual-action formula. By combining two powerful active ingredients, it targets grasses, sedges, and broadleaf weeds effectively without harming your crop.
Best For: Farmers looking to reduce manual weeding labor and prevent yield loss in Transplanted Rice (Paddy).
Why Choose This Product? Key Benefits

How It Works: Mode of Action
Fiesta Forte utilizes a unique combination to prevent weed resistance and ensure broad coverage:
- Stops Cell Division (Pretilachlor): This component attacks grassy weeds by inhibiting their cell division process, effectively stopping growth immediately after germination.
- Blocks Protein Synthesis (Pyrazosulfuron): This ALS inhibitor blocks the creation of essential amino acids (valine, leucine, isoleucine), starving broadleaf weeds and sedges.
- Barrier Formation: The granules dissolve to form a chemical layer on the soil surface. Weeds attempting to emerge contact this layer and absorb the lethal dose.
Note: This dual mechanism makes it highly effective against complex weed flora that single-molecule herbicides might miss.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Transplanted Rice (Paddy) | Barnyard Grass (Echinochloa spp.), Chinese Sprangletop |
| Transplanted Rice (Paddy) | Rice Flat Sedge, Hoorahgrass (Fimbristylis miliacea) |
| Transplanted Rice (Paddy) | Broadleaf Weeds: Bhringraj, Water Primrose |
Dosage & Application Guide
The Golden Rule: Always follow the "Time of Application" strictly (0-3 days) for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (kg / Acre) | Water Condition | Method | PHI (Days) |
|---|---|---|---|---|
| Transplanted Rice | See Product Label* | Standing Water Required | Broadcasting (Hand) | -- |
*Note: Exact dosage depends on local soil conditions and weed pressure. Always refer to the official leaflet included with the pack (e.g., 4kg - 5kg packs common).
How to Apply: Best Practices
- Timing: STRICTLY apply between 0 to 3 days after transplanting. Effectiveness drops significantly if applied after weeds have emerged.
- Mixing: Do not dissolve in water tanks. This is a granular product meant for direct broadcasting by hand or mechanical spreader.
- Coverage: Ensure the field has standing water (roughly 2-3 inches) during application. This helps the granules dissolve and spread the active ingredient uniformly over the soil surface.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhalation of dust.
