Hercules Insecticide (Difenthiuron 40.1% + Acetamiprid 3.9% WP)
The "One-Shot" Solution for Whiteflies, Thrips, Mites, and Aphids.
Hercules is a premium, broad-spectrum insecticide developed by Insecticides (India) Ltd to fight the toughest sucking pests. It combines two powerful active ingredients to create a "Hammer and Anvil" effect: one attacks from the outside with vapor action, while the other protects the plant from the inside.
Best For: Cotton, Chili, and Vegetable farmers facing complex pest mixtures (like Mites + Thrips) who need rapid results and long-lasting protection.

-
⏱️
Double Action Power: Combines immediate "knockdown" of adults with a long residual effect that lasts 14 to 21 days.
-
🛡️
No Place to Hide: The unique Vapor Action turns the chemical into gas, reaching pests hiding under leaves and inside flower buds where sprays usually miss.
-
⏳
Stops the Next Generation: It is Ovicidal (kills eggs) and suppresses the egg-laying ability of female whiteflies, breaking the pest life cycle.
-
🌧️
Sunlight Activated: Bright sunlight helps activate the chemical for maximum potency. It becomes rainfast within 4-6 hours of application.
-
🌿
Phytotonic "Greening" Effect: Farmers report a distinct green sheen and improved crop vigor after spraying, likely due to the sulfur and nitrogen boost in the formula.

How It Works: Mode of Action
Hercules uses a dual-strategy to kill pests that have developed resistance to ordinary sprays.
- The Hammer (Vapor Action): Difenthiuron turns into a gas upon contact with sunlight. This gas penetrates leaf crevices and undersides, shutting down the pest's breathing system (Mitochondrial respiration).
- The Anvil (Systemic Action): Acetamiprid enters the plant leaves and travels upward. It acts as a neurotoxin, permanently exciting the insect's nervous system until paralysis occurs.
- Life Cycle Disruption: It kills existing bugs instantly while residue on the leaf prevents eggs from hatching for weeks.
Result: Total paralysis and death of the pest complex.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not cut corners on water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 250 - 300g | 150 - 200 L | 1.5 - 2.0g | 15-20 |
| Chili | 250 - 300g | 150 - 200 L | 1.5 - 2.0g | 15-20 |
| Vegetables | 250 g | 150 L | 1.5g | 15 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: For severe whitefly infestations (>10 adults/leaf), use 300g/acre.
How to Apply: Best Practices
- Timing: Spray in the morning. As the day warms up, sunlight activates the Difenthiuron vapor for maximum efficacy.
- Mixing: This is a Wettable Powder. First, mix the dose in a small bucket of water (make a slurry) before pouring it into the main tank. Agitate continuously.
- Coverage: Ensure the undersides of leaves are wet, as this is where whiteflies and mites hide. Use high water volume (min 150L/acre).
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray during peak bee activity.
Frequently Asked Questions
1. Does Hercules kill Mites?
Yes. It acts as a powerful miticide. It is an excellent cost-saving choice for Chili farmers because you don't need to buy a separate spray for mites.
2. Can I mix fungicides with Hercules?
Yes, it is generally compatible with fungicides like Carbendazim, Mancozeb, and Copper Oxychloride. However, avoid mixing with alkaline products like Lime Sulfur or Bordeaux mixture.
3. Why do I need to use so much water (150L+)?
Low water volume concentrates the chemical too much, which can burn the leaves (phytotoxicity). High water volume ensures safe coverage and better vapor action.
4. Is it safe for flowers?
The product is toxic to bees. Avoid spraying when crops are in full bloom during the day. If necessary, spray in the late evening when bees are not active.
5. How fast will I see results?
You will see adult pests dying within hours due to the Acetamiprid component. The full control of hidden nymphs and mites will happen over the next 2-3 days as the vapor takes effect.
