How It Works: Mode of Action
Parryfos uses a "Triple Threat" mechanism to ensure no pest escapes.
- Systemic Action: Absorbed by roots and foliage, it travels through the plant's sap to kill sucking pests that pierce the plant tissue.
- Contact Action: It kills mobile pests and larvae instantly when the spray droplets land on them.
- Stomach Action: Chewing pests (like bollworms) die after eating leaves treated with the chemical.
Biochemically, it inhibits the enzyme acetylcholinesterase, leading to pest paralysis and elimination.

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 | 400 - 600 ml | 200 L | 2.0 - 3.0 ml | ~30 Days |
| Paddy | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 30 Days |
| Pulses | 400 ml | 200 L | 2.0 ml | 30 Days |
*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 "early stage of pest infection" or when egg hatching is observed for best results.
- Mixing: Do NOT mix with highly alkaline substances (like Bordeaux mixture) as the product loses efficacy. It is compatible with most other acidic/neutral sprays.
- Coverage: Use high-volume knapsack sprayers to ensure thorough coverage of foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not inhale spray mist.
