How It Works: Mode of Action
Corprima works by targeting the insect's muscular system via the Ryanodine Receptors.
- Ingestion: The pest eats the treated leaf or fruit surface.
- Activation: The active ingredient binds to the muscle receptors, forcing them to release all stored calcium.
- Paralysis: This calcium depletion causes immediate muscle paralysis. The insect stops moving and feeding instantly, eventually dying of starvation.
Result: Your crop damage stops immediately, preserving flower and fruit quality.

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 (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tomato | 34 gm | 200 L | 0.17 gm | 1-3 Days |
| Okra | 34 gm | 200 L | 0.17 gm | 1-3 Days |
| Small Farms (Spray Tank) | — | 15 L Tank | 2.5 gm per Tank | — |
*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 egg-laying stage or when you see the first signs of pest activity (flower drop or fruit damage).
- Mixing: Corprima granules dissolve quickly. Mix the required quantity in a small bucket of water first, then add to the main tank.
- Coverage: Ensure thorough coverage of the foliage. The product has translaminar movement (moves through the leaf), which helps reach pests hiding underneath.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. I see pests alive after spraying. Is it not working?
Don't worry. Corprima causes muscle paralysis. The larvae might look alive, but they stop feeding within minutes and cannot damage your crop. They will die shortly.
2. I searched for "Corproma" but found a medicine. Is this the same?
No! "Corproma" is a common typo. The insecticide is Corprima by FMC. The medicine (Chlorpromazine) is completely different. Always check for the FMC logo.
3. Can I use this during flowering?
Yes. Corprima is "Green Chemistry" and is generally safe for pollinators when applied correctly, leading to better flower retention.
4. What pack sizes are available?
FMC offers Corprima in 6gm (trial), 17gm, and 34gm (commercial) packs to suit different farm sizes.
5. Does it control sucking pests like Aphids?
No. Corprima is highly specialized for chewing pests (caterpillars/borers). For sucking pests, you may need a tank mix partner (consult an agronomist).
