HPM Histar Insecticide (Bifenthrin 10% EC) | Ultimate Termite & Crop Protection
The "Itch-Free" solution for broad-spectrum pest control in Cotton, Paddy, and Construction.
HPM Histar is a new-generation synthetic pyrethroid containing Bifenthrin 10% EC. Unlike older pesticides that cause severe skin burning and itching, Histar features unique "No Alpha-Cyano" chemistry, making it safer and more comfortable for farmers to spray.
Dual Power: It acts as a powerful protector for your crops against chewing and sucking pests, and creates an impenetrable chemical barrier against termites in soil and building foundations.

How It Works: Mode of Action
Histar works by targeting the nervous system of the insect.
- Sodium Channel Modulation: It keeps the sodium channels in the pest's nerve cells open for too long.
- Hyperexcitability: This causes the insect's nerves to fire uncontrollably (tremors), leading to rapid paralysis.
- Zone of Denial: For termites, it acts as a repellent. Termites detect the chemical barrier in the soil and turn away, preventing them from ever reaching the crop or structure.
Bonus: Histar often provides a "Phyto-tonic" effect, making crops appear greener and healthier after application.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Bollworms (American & Pink), Whitefly |
| Paddy (Rice) | Stem Borer, Leaf Folder, Green Leaf Hopper |
| Sugarcane / Construction | Termites (Subterranean) |
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) |
|---|---|---|---|---|
| Cotton | 320 ml | 200 L | 1.6 ml | 15 |
| Paddy (Rice) | 200 ml | 200 L | 1.0 ml | 21 |
| Termites (Soil) | 400 - 500 ml | 500 L | ~ 1.0 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For crops, apply during vegetative or early flowering stages. Avoid spraying during full bloom to protect bees.
- Mixing: Use the "Pre-Mix" method. Mix the dose in a small bucket of water first, then pour it into the main tank.
- Coverage: Use high water volume (200L+ per acre) to ensure the spray penetrates the canopy to reach pests hiding under leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Highly toxic to fish—do not use near ponds.
Frequently Asked Questions
1. Does Histar cause skin itching like other poisons?
No, Histar uses "No Alpha-Cyano" chemistry, which significantly reduces the burning sensation (paresthesia) common with other pyrethroids, making it much easier to handle.
2. Is this effective against Termites?
Yes, Histar is a premium termiticide. It binds to soil particles to create a long-lasting chemical barrier that repels and kills termites.
3. Can I use it for vegetables?
Yes, it is effective against mites and thrips in vegetables. Ensure you follow the correct dosage (~1.25ml per Litre) and observe a safe gap before harvesting.
4. Is Histar rainfast?
Yes, due to its low water solubility and high lipophilicity (oil-loving nature), it sticks well to plant surfaces and is resistant to washing off by rain.
5. What is the shelf life of the product?
When stored in a cool, dry place away from direct sunlight, Histar generally maintains stability for 2 years from the date of manufacture.
