How It Works: Mode of Action
Corprima operates on the muscular system of the insect, making it effective even against pests resistant to other chemicals.
- Ingestion & Contact: The pest ingests the chemical while trying to feed or comes into direct contact with the spray.
- Muscle Paralysis: The active ingredient binds to Ryanodine Receptors, causing an uncontrolled release of calcium in the insect's muscles.
- Feeding Cessation: This leads to instant muscle paralysis. The insect stops feeding immediately and dies from starvation within a few days, saving your crop instantly.
*Safe for beneficial insects like bees and ladybird beetles, making it great for IPM (Integrated Pest Management).
Target Crops & Pests

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Due to the high concentration (35%), a very small quantity is required.
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 | 3 Days |
| Okra | 34 gm | 200 L | 0.17 gm | 5 Days |
| Note | Use 1 Sachet (34g) | Per Acre | - | - |
*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 incidence or during the flowering/fruiting stage for maximum protection.
- Mixing: Corprima is a WG (Granule) formulation. Dissolve the required quantity in a small amount of water first, then add to the main tank.
- Coverage: Ensure thorough coverage of foliage. The product has translaminar activity (moves from upper to lower leaf surface), helping kill hidden pests.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
