Fortenza® Duo Insecticide (Cyantraniliprole + Thiamethoxam)
The Ultimate Seed Shield: Expert Protection Against Fall Armyworm & Shoot Fly.
Fortenza® Duo is a next-generation seed treatment designed specifically to protect hybrid maize from invasive pests during the critical first 30-40 days. By combining two powerful active ingredients, it creates a "Bulb of Protection" around the roots and a systemic shield inside the plant.
Don't rely on luck or late sprays. Secure your crop stand, ensure uniform germination, and maximize your yield potential right from the start.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Feeding Cessation: Pests stop eating within minutes of ingesting the treated plant tissue, preventing "dead hearts" and seedling loss.
-
🛡️
Dual-Action Power: The only seed treatment that effectively controls both chewing pests (Fall Armyworm, Cutworms) and sucking pests (Shoot Fly, Aphids).
-
⏳
Long-Lasting Defense: Provides robust residual protection for up to 30–40 days after sowing, covering the most vulnerable growth stage.
-
🌧️
"Bulb of Protection": Creates a protective zone in the soil around the roots, stopping soil-dwelling pests like Cutworms and Termites before they reach the plant.
-
🌿
Crop Vigor Effect: Promotes stronger root development and better stress tolerance (drought/heat), ensuring a healthy plant stand even in tough conditions.

How It Works: Mode of Action
Fortenza® Duo employs a dual-attack strategy to ensure complete protection.
- Muscle Paralysis (Cyantraniliprole): Upon ingestion, this component binds to Ryanodine receptors in the pest's muscles. It forces calcium channels open ($Ca^{2+}$ depletion), leading to immediate muscle paralysis and death.
- Nerve Over-Stimulation (Thiamethoxam): This component is rapidly absorbed by roots and moves up the stem. It targets the pest's nervous system, causing tremors and hyperexcitation, which effectively stops sucking pests like Shoot Fly.
- Systemic Translocation: As the seedling grows, the active ingredients travel up through the xylem, protecting new leaves that emerge weeks after sowing.
Result: The plant is protected from the inside out, and the soil around the root is protected from the outside in.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Fall Armyworm (Spodoptera frugiperda) |
| Maize (Corn) | Shoot Fly, Stem Borer, Aphids, Shoot Bug |
| Maize (Corn) | Soil Pests: Cutworms, Termites |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per kg of Seed" for accurate results. Unlike sprays, this is applied to the seed before sowing.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / kg Seed) | PHI (Days) |
|---|---|---|---|---|
| Maize (For Shoot Fly/Stem Borer) | 32 ml (approx) | Slurry Prep* | 4 ml / kg | NA |
| Maize (For Fall Armyworm) | 48 ml (approx) | Slurry Prep* | 6 ml / kg | NA |
*Slurry Prep: Mix the required dose with a small amount of water (approx 10-15ml per kg of seed) to ensure uniform coating. *Calculations based on 8kg seed per acre.
How to Apply: Best Practices
- Timing: Treat seeds before sowing. Shake the Fortenza Duo bottle vigorously for 10 seconds before opening.
- Mixing (Plastic Bag Method): 1. Prepare slurry (Dose + Water). 2. Pour slurry into a heavy-duty plastic bag and coat the walls. 3. Add seeds, trap air to make a balloon, and shake/roll for 1-2 minutes until seeds are uniformly colored.
- Drying: Spread treated seeds on a plastic sheet in a shaded, well-ventilated area. Do not dry under direct sunlight as UV rays degrade the chemical.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use treated seed for food or feed.
Frequently Asked Questions
1. What is the pack size available?
It is commonly available in a 32 ml bottle, which is sufficient for one acre of maize if targeting Shoot Fly (at 4ml/kg). For Fall Armyworm (6ml/kg), you will need approx 1.5 bottles per acre.
2. Can I mix Fortenza Duo with fungicides?
Yes, it is compatible with seed treatment fungicides like Maxim® (Fludioxonil) or Apron XL® to add protection against soil fungus.
3. How long does the protection last?
Fortenza® Duo provides residual protection for 30 to 40 days after sowing, covering the crop's most sensitive establishment phase.
4. Do I need to spray for FAW later?
This product protects the early stage. Monitor the field after 30-40 days. If pest pressure is high then, a foliar spray (like Emamectin Benzoate) may be required, but you will have saved the cost of the first 1-2 sprays.
5. Is it safe for the operator?
It is a "Blue Triangle" (Moderately Toxic) product. It is safer than many older chemicals, but you must always wear gloves and protective clothing during the mixing and sowing process.
