By combining two powerful active ingredients with advanced Oil Dispersion (OD) technology, it delivers complete broad-spectrum control, replacing the need for expensive manual weeding.
Why Choose Felicita? Key Benefits for Rice Farmers
- ⏱️Fast-Acting Control: Weeds stop growing within hours of spraying. Visual yellowing appears in 7-14 days, with complete death in 2-4 weeks.
- ?️Double Action Power: Combines Penoxsulam and Cyhalofop-Butyl to kill a wide range of weeds—Grasses, Sedges, and Broadleaves—in a single shot.
- ⏳Flexible Timing: Effective during the early post-emergence window (15-25 Days After Transplanting/Sowing), targeting weeds at the 2-4 leaf stage.
- ?️Superior Rainfastness: Thanks to OD technology, the spray sticks to leaves and becomes rain-proof within just 1 hour, making it perfect for the monsoon season.
- ?100% Crop Safe: Highly selective to rice plants. It destroys weeds systemically without harming your paddy crop when used as directed.

How It Works: Mode of Action
Felicita uses a "Dual-Attack" mechanism to overcome weed resistance. By attacking two different biological systems in the weed, it ensures complete control where single-molecule herbicides might fail.
- Penoxsulam (The ALS Inhibitor): Systemically absorbed through leaves and roots, it stops the production of essential amino acids (protein building blocks). This rapidly halts cell division in Broadleaf weeds and Sedges.
- Cyhalofop-Butyl (The ACCase Inhibitor): Specifically targets grassy weeds. It blocks the enzyme responsible for fatty acid synthesis, destroying cell membranes and causing the collapse of the growing points in grasses like Echinochloa.
- The OD Advantage: The oil-based formulation helps the herbicide penetrate the waxy layers of tough weeds and spread evenly across the leaf surface, ensuring no weed escapes.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Transplanted & DSR) | Grasses: Barnyard Grass (Echinochloa crus-galli), Jungle Rice (Echinochloa colona), Chinese Sprangletop (Leptochloa chinensis). |
| Rice (Transplanted & DSR) | Sedges: Smallflower Umbrella Sedge (Cyperus difformis), Rice Flatsedge (Cyperus iria). |
| Rice (Transplanted & DSR) | Broadleaf Weeds: False Daisy (Caesulia axillaris), Sessile Joyweed (Alternanthera sessilis), Commelina spp. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Transplanted Rice | 800 - 900 ml | 150 - 200 Litres | 4.5 - 6 ml | 60 |
| Direct Seeded Rice (DSR) | 800 - 900 ml | 150 - 200 Litres | 4.5 - 6 ml | 60 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when weeds are actively growing and are at the 2 to 4 leaf stage (usually 15-25 days after sowing/transplanting). Early or very late application may reduce results.
- Water Management (Crucial): 1. Drain the field before spraying so weed leaves are exposed.
2. Spray the herbicide evenly.
3. Re-flood the field 48-72 hours after spraying to suppress new weeds. - Coverage: Use a Knapsack or Power Sprayer with a Flat Fan or Flood Jet nozzle for uniform coverage. Do not use Cone nozzles.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying on windy days to prevent drift.
Frequently Asked Questions
1. Is Felicita rainfast?
Yes, due to its Oil Dispersion (OD) formulation, it becomes rainfast within 1 hour of application.
2. Can I mix Felicita with insecticides?
Yes, studies show it is compatible with insecticides like Fipronil (for stem borer) without harming the rice crop or reducing efficacy.
3. What happens if I spray when the water level is high?
If weeds are submerged, the spray will hit the water instead of the leaves, making it ineffective. Always drain the field before application.
4. Does it control full-grown weeds?
It is most effective at the 2-4 leaf stage. Older weeds (tillering stage) develop thicker skins and are harder to kill, so timely application is key.
5. Will it harm my rice crop?
No, rice plants can metabolize (break down) the active ingredients quickly, making it safe. However, avoid spraying if the crop is under severe stress from cold or disease.
