Prime Insecticide (Acetamiprid 20% SP) by Nichino
The ultimate expert solution for controlling sucking pests like Aphids, Jassids, and Whiteflies in Cotton, Rice, and Vegetables.
Prime (Acetamiprid 20% SP) is a high-quality systemic insecticide manufactured by Nichino India (a subsidiary of Nihon Nohyaku, Japan). It is designed to provide rapid and long-lasting protection against hard-to-kill sucking pests. Unlike older chemicals, Prime offers a safer profile for applicators and plants while delivering a "Quick Knockdown" effect on pests.
Best for: Farmers facing yield loss due to sucking pests, "Hopper Burn," or viral transmission (like Leaf Curl Virus) by whiteflies.
Why Choose This Product? Key Benefits
-
⏱️
Quick Knockdown Effect: Stops pests from feeding immediately upon contact. This prevents further damage and halts the injection of toxins into the plant.
-
🛡️
Systemic & Translaminar Action: Prime penetrates the leaf and moves to the underside where pests hide. It also travels upward (acropetal) to protect new shoot growth.
-
⏳
Long Duration Control: Provides reliable protection for 10 to 15 days, reducing the need for frequent spraying and saving labor costs.
-
🌧️
Excellent Rainfastness: The product is absorbed quickly and is resistant to rain wash-off within 2 to 4 hours of application, making it perfect for the Kharif (monsoon) season.
-
🌿
Low Toxicity to Bees: Compared to other neonicotinoids, Acetamiprid is safer for honeybees and beneficial pollinators, supporting sustainable agriculture.

How It Works: Mode of Action
Prime works by targeting the nervous system of the insect.
- Transmission: Once sprayed, the active ingredient is absorbed by the plant and spreads systemically.
- Ingestion: When Aphids or Jassids suck the plant sap, they ingest the Acetamiprid.
- Paralysis: The chemical binds to the insect's nerve receptors (nAChR), causing hyper-excitation, paralysis, and rapid death.
Because it affects a different site than organophosphates, it is highly effective even against pests that have developed resistance to older chemicals.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Aphids, Jassids, Whiteflies |
| Rice (Paddy) | Brown Plant Hopper (BPH) |
| Chilli, Okra, Cabbage | Thrips, Aphids, Leafhoppers |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 20g - 40g | 200 Litres | 0.1g - 0.2g | 15 |
| Rice (Paddy) | 20g - 40g | 200 Litres | 0.1g - 0.2g | 7 |
| Chilli / Okra | 20g - 40g | 200 Litres | 0.1g - 0.2g | 3 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage is in Grams (g) as Prime is a powder.
How to Apply: Best Practices
- Timing: Apply as soon as pest population reaches the Economic Threshold Level (e.g., 2 nymphs per leaf for Jassids).
- Mixing: Prime is a Soluble Powder (SP) that dissolves easily. Add the required quantity of powder to a small amount of water to make a solution, then add to the main tank.
- Coverage: Ensure thorough coverage of the foliage. For Rice/Paddy, drain the field before spraying to allow the chemical to reach the stem base (BPH zone).
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
