Why Choose This Product? Key Benefits
- ⏱️Rapid Knockdown Action: Instantly stops pests from feeding upon contact, minimizing crop damage immediately.
- ?️Dual-Use Powerhouse: Acts as both a potent crop insecticide for sucking/chewing pests and a professional-grade termiticide for soil barriers.
- ⏳Long-Lasting Soil Barrier: The unique chemistry binds tightly to soil particles, creating a termite shield that lasts for years without leaching into groundwater.
- ?️Weather & Photostable: Remains active on leaves for 15-21 days and does not degrade easily in sunlight, reducing the need for frequent re-spraying.
- ?Low Skin Irritation: Formulated without the "alpha-cyano" group, significantly reducing the burning or itching sensation (paresthesia) common with other pyrethroids.

How It Works: Mode of Action
Histar attacks the nervous system of insects, causing hyperexcitability and paralysis. It employs a "Three-Pronged" attack strategy to ensure total control:
- Contact Action: The primary mode. Insects that crawl over treated soil or leaves absorb the lethal dose instantly through their skin.
- Stomach Action: Essential for chewing pests like Bollworms and Termites. When they eat treated wood or leaves, the toxin destroys them from the inside.
- Repellent "Zone of Denial": Unique to Histar, it creates a chemical barrier that termites detect and avoid, preventing them from even entering the treated area.
*Also provides a "Phyto-tonic" effect, improving crop greenness and vigor.
Target Crops & Pests

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 - 300 L | ~1.6 ml | 15 Days |
| Rice (Paddy) | 200 ml | 200 L | 1 ml | 21 Days |
| Sugarcane (Termites) | 400 - 500 ml | 500 L | ~1 ml | N/A |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply during the "Vegetative to Flowering" stage for crops. For termites, apply as a soil drench before covering seeds/setts or during construction.
- Mixing: Use the "Pre-Mix" method. Mix the dose in a small bucket of water (1-2L) first, then pour that into the main knapsack tank.
- Coverage: Ensure full coverage of the foliage, especially the undersides of leaves where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds or when bees are active.
Frequently Asked Questions
1. Does HPM Histar cause skin burning/itching?
Significantly less than others. Histar uses a "No Alpha-Cyano" chemistry which minimizes the skin irritation and tingling sensation common with standard pyrethroids.
2. Can I use Histar for Termite control in my house?
Yes. Histar is an excellent termiticide. For construction, it creates a chemical barrier in the soil that prevents termites from entering the foundation.
3. Is it rainfast?
Yes, Histar has high lipophilicity (oil-loving), meaning it binds quickly to leaf surfaces and soil. It generally remains effective even if it rains a few hours after drying.
4. What is the correct dosage for a 15-liter pump?
For Cotton, use approx 25-30ml per 15L tank. For Rice/Paddy, use approx 20ml per 15L tank. (Always calculate based on acre requirements).
5. Can I mix Histar with other chemicals?
Do not mix with alkaline products (like Bordeaux mixture) as they degrade the insecticide. Always perform a small jar test before mixing with other pesticides.
