Talextra Insecticide (Imidacloprid 20% + Bifenthrin 8% SL)
The Ultimate Dual-Action Solution for Sucking and Chewing Pests.
Arthropod pests are responsible for approximately **40% of global crop losses** annually. To combat this, you need a solution that hits harder and lasts longer. Talextra by Krishi Rasayan is a premium pre-mix formulation combining Imidacloprid (20%) and Bifenthrin (8%).
Why is this mix superior? It eliminates the hassle of manual tank mixing. Talextra provides a synergistic "Double Punch": it delivers immediate knockdown of visible pests like Bollworms while systematically protecting your crop from "hidden" sucking pests like Aphids and Whiteflies. This broad-spectrum control makes it the ideal choice for high-value crops like Cotton, Rice, and Vegetables.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Power: The Bifenthrin component attacks the pest's nervous system immediately upon contact, stopping crop damage within minutes of application.
-
🛡️
Systemic "Hidden Pest" Control: Imidacloprid penetrates the plant system, killing pests hiding under leaves or inside curled foliage that standard sprays miss.
-
⏳
Dual-Site Action: By targeting two different sites in the insect nervous system (Sodium Channels and nAChR), it effectively kills pests resistant to single-molecule sprays.
-
🌧️
Rainfast & Photostable: The formulation binds tightly to the leaf surface and resists degradation from sunlight, providing longer residual protection than generic pyrethroids.
-
🌿
Phytotonic "Green" Effect: Beyond pest control, the systemic action helps protect new shoot growth, keeping your crop lush and green during the critical vegetative phase.

How It Works: Mode of Action
Talextra uses a sophisticated "Synergistic Attack" mechanism that insects cannot easily adapt to:
- Systemic Entry (The Anchor): Imidacloprid (20%) is absorbed by the plant roots and leaves. It travels through the xylem to new growth, poisoning the sap. When sucking pests feed, their nerve receptors are permanently blocked, leading to paralysis.
- Contact Shock (The Hammer): Bifenthrin (8%) stays on the leaf surface. It acts as a sodium channel modulator. Any insect walking over the treated area or eating the leaf suffers immediate hyperexcitation and rapid knockdown.
- Total Collapse: The combination of continuous nerve firing (Imidacloprid) and the inability to close sodium channels (Bifenthrin) causes irreversible failure of the insect's nervous system.
This 2.5:1 ratio (20 parts Imidacloprid to 8 parts Bifenthrin) is chemically engineered to prevent sedimentation and ensure every drop sprayed is equally lethal.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Aphids, Jassids, Thrips, Whiteflies, Spotted & Pink Bollworms |
| Paddy (Rice) | Brown Plant Hopper (BPH), Green Leaf Hopper, Stem Borer, Leaf Folder |
| Sugarcane & Tea | Termites, Early Shoot Borer, Tea Mosquito Bug (Helopeltis) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Under-dosing can lead to pest resistance.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 500 ml | 150 - 200 L | 2.5 - 3.0 ml | Refer to Label |
| Paddy (Rice) | 500 ml | 150 - 200 L | 2.5 - 3.0 ml | Refer to Label |
| Vegetables | 200 - 400 ml | 150 L | 1.3 - 2.0 ml | 5 - 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always ensure sufficient water volume for canopy penetration.
How to Apply: Best Practices
- Timing: Apply during the "transition phase" (e.g., 45-60 days in cotton) when both sucking pests and early caterpillars are present. Avoid spraying during active bee foraging hours.
- Mixing: Compatible with most neutral fertilizers and fungicides. Warning: Do not mix with alkaline products (like Bordeaux mixture) as this neutralizes the Bifenthrin instantly.
- Coverage: Use a Hollow Cone Nozzle for the best mist. Ensure you use at least 150 Liters of water per acre to reach the undersides of leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Bifenthrin can cause skin tingling; wash hands thoroughly after use.
Frequently Asked Questions
1. What is the main advantage of using Talextra over standard Cypermethrin?
Talextra offers systemic action via Imidacloprid, which Cypermethrin lacks. This means Talextra kills pests hiding inside curled leaves, whereas Cypermethrin only kills what it touches.
2. Can I use Talextra for termite control?
Yes. The Bifenthrin component is a premier termiticide. For crops like Sugarcane, a soil drench creates a chemical barrier that repels and kills termites effectively.
3. Is this product safe for honeybees?
No. Imidacloprid is highly toxic to bees. Do not spray during full bloom or when bees are actively foraging. Spray in the late evening to minimize impact on pollinators.
4. What is the dose for a 15-liter pump?
For a standard 15-liter knapsack sprayer, use approximately 30ml to 40ml of Talextra, depending on pest severity.
5. Does it control mites?
Talextra has mite-suppressing properties due to Bifenthrin, but for severe mite infestations, a dedicated miticide might be required.
