How It Works: Mode of Action
Trishul acts as a potent neurotoxin that targets the nervous system of insects.
- Entry: It enters the pest's body through skin contact, ingestion (eating treated leaves), or inhalation of vapors.
- Inhibition: It binds to and blocks Acetylcholinesterase (AChE), a vital enzyme responsible for stopping nerve signals.
- Termination: This blockage causes continuous firing of nerve impulses, leading to paralysis and the rapid death of the pest.
Note: The "vapor action" allows it to kill pests hiding in soil or on the undersides of leaves.

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 | 500 - 1200 ml | 200 - 300 L | 2.5 - 4 ml | 30 Days |
| Paddy | 500 - 1200 ml | 200 - 300 L | 2.5 - 4 ml | 15-21 Days |
| Sugarcane (Termites) | 600 - 1500 ml | 300 - 500 L | Soil Drench | 30 Days |
| Termites (Buildings) | - | - | Mix 1L in 19L Water | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest infestation. For termites, treat the soil during construction or inject into the floor for existing buildings.
- Mixing: For termites, use a ratio of 1 part Trishul to 19 parts water. For crops, mix the required dose in a small amount of water first, then add to the main tank.
- Coverage: Ensure high-volume spraying for soil drenching to create a deep chemical barrier. For crops, ensure full canopy coverage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
Frequently Asked Questions
1. Is Trishul effective against Termites?
Yes, Trishul is highly effective for both pre-construction (foundation treatment) and post-construction termite control. It creates a lethal barrier in the soil.
