Himawari Insecticide (Profenofos 40% + Cypermethrin 4% EC)
The Ultimate "One-Shot" Solution for Hard-to-Kill Bollworms and Sucking Pests.
Himawari by IFFCO MC is a powerful, broad-spectrum insecticide designed for modern Indian agriculture. By combining two distinct chemical classes—Organophosphates and Synthetic Pyrethroids—it delivers a "double punch" to pests. It is specifically engineered to control complex pest guilds in Cotton, Paddy, and Vegetables, offering effective relief against pests that have developed resistance to single-molecule sprays.
Best For: Farmers seeking a cost-effective, mid-season solution for mixed infestations of chewing and sucking insects.

How It Works: Mode of Action
Himawari attacks the insect nervous system from two different angles, ensuring that pests cannot survive or develop resistance easily.
- The Shock (Contact Action): Cypermethrin binds to sodium channels in the pest's nerves, causing immediate paralysis (knockdown) so they stop feeding instantly.
- The Deep Clean (Translaminar Action): Profenofos penetrates the leaf tissues. When sucking pests (like mites/thrips) feed on the leaf, they ingest the poison.
- The Enzyme Block (Systemic Failure): Profenofos inhibits Acetylcholinesterase (AChE), causing the pest's nervous system to overfire, leading to tremors and death.
This combination effectively bypasses the metabolic resistance mechanisms that pests use to survive standard pyrethroid sprays.

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 - 300 L | 2.0 - 3.0 ml | 14 - 21 |
| Paddy (Rice) | 400 - 500 ml | 150 - 200 L | 2.0 - 2.5 ml | 14 - 21 |
| Vegetables | 400 - 500 ml | 150 - 200 L | 2.0 - 2.5 ml | 7 - 10 |
| Maize / Wheat | 400 - 500 ml | 150 - 200 L | 2.5 ml | 14+ |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Apply when pest population crosses the Economic Threshold Level (e.g., 5% damaged bolls). Spray in the evening to avoid harming bees and to reduce evaporation.
- Mixing: Use clear water. Ensure sufficient water volume (min 200L/acre for knapsack sprayers) to thoroughly wet the crop canopy.
- Coverage: The product works best when it hits the pest directly or the pest eats the treated leaf. Ensure nozzles are targeted at both upper and lower leaf surfaces.
- Safety: Always wear PPE (gloves, mask, goggles). Cypermethrin can cause a temporary burning sensation on facial skin; avoid direct contact. Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Himawari effective against Pink Bollworm?
Yes, it is effective as a mid-season spray. Its ovicidal action kills eggs, and Profenofos penetrates the boll rind to kill early-stage larvae.
2. Does it control mites in chilli?
Yes, the Profenofos component is a proven acaricide (mite-killer), making it excellent for controlling "Murda" (leaf curl) caused by thrips and mites in chilli.
3. What is the approximate cost per acre?
Himawari is very economical, typically costing around ₹500 per acre (at a 500ml dose), making it cheaper than many modern diamide insecticides.
4. Can I mix it with other fungicides?
Yes, it is generally compatible with most common fungicides. However, always perform a small jar test before mixing in the main tank.
5. Why does my skin burn after spraying?
This is a common effect of Cypermethrin (Paresthesia). It is temporary. Apply Vitamin E oil or cold cream to soothe it, and always wear a mask and goggles to prevent it.
