Carina Insecticide (Profenofos 50% EC): Complete Control for Worms & Mites
Looking for a powerful solution to tackle tough chewing and sucking pests?
Carina (Profenofos 50% EC) by PI Industries is a broad-spectrum organophosphate insecticide. It is specially engineered to fight resistant caterpillars (bollworms) and sucking pests like mites simultaneously. Its "translaminar" ability allows it to penetrate leaves to kill pests hiding on the underside, making it a favorite for Cotton, Soybean, and Rice farmers.

How It Works: Mode of Action
Carina attacks the insect's nervous system through three powerful methods:
[Image of acetylcholinesterase inhibition mechanism]- Contact & Stomach Action: Immediate paralysis occurs when the pest touches the spray or eats treated leaves.
- Nerve Inhibition: It blocks the enzyme Acetylcholinesterase, causing a "short circuit" in the pest's nerves, leading to paralysis and death.
- Translaminar Movement: The chemical moves through the leaf layers, creating a toxic reservoir that kills pests hiding underneath.
Note: This multi-pathway entry makes it difficult for pests to hide or survive.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Bollworms, Jassids, Aphids, Mites, Thrips |
| Soybean | Semilooper, Girdle Beetle, Tobacco Caterpillar |
| Rice (Paddy) | Stem Borer, Leaf Folder, Brown Plant Hopper (BPH) |
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 | 600 - 800 ml | 200 L | 3 - 4 ml | 15 Days |
| Soybean | 400 - 500 ml | 200 L | 2 - 2.5 ml | 40 Days |
| Rice (Paddy) | 400 - 600 ml | 200 L | 2 - 3 ml | 28 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 when pest population crosses the Economic Threshold Level (ETL) or when eggs/early larvae are seen.
- Mixing: Compatible with Carbendazim and Copper Oxychloride. Do NOT mix with alkaline substances like Bordeaux mixture or Lime Sulfur.
- Coverage: Use sufficient water (minimum 200L/acre) to ensure the spray reaches the lower leaves where mites hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Carina kill mites (Acaricide)?
Yes, Carina is unique because it kills both insects (caterpillars) and mites (Red Spider Mite) in a single spray, saving you the cost of a separate miticide.
2. Is it safe for honeybees?
No, Profenofos is toxic to bees. Avoid spraying during peak pollination hours. Spray in the late evening when bee activity is low.
3. What happens if it rains after spraying?
Carina is rainfast within 3 to 4 hours. If it rains after this period, you generally do not need to re-spray.
4. Can I use it for vegetables?
Yes, it is effective for vegetables like Brinjal and Cabbage, but strictly follow the waiting period (PHI) of 10-14 days before harvest to ensure safety.
5. Why is Carina called a "Rescue Chemistry"?
It is often used when other pesticides (like pyrethroids) fail to kill resistant pests. It acts as a powerful backup to clean up the field.
