Crystal Looper Insecticide (Imidacloprid 70% WG)
The Ultimate Systemic Solution for Sucking Pests in Cotton, Paddy, and Vegetables.
Crystal Looper is a high-performance insecticide designed to tackle tough sucking pests like Jassids, Aphids, and Brown Plant Hoppers (BPH). Powered by Imidacloprid 70% WG, this advanced "Water Dispersible Granule" formulation dissolves quickly and provides powerful protection at very low doses. Unlike older liquid sprays, Looper works from the inside out, turning the plant itself into a fortress against pests.
Note: While the brand name is "Looper," this product targets sucking pests (Hoppers/Aphids), not the "Looper Caterpillar."
Why Choose Crystal Looper? Key Benefits
-
⏱️
Rapid Systemic Action: Absorbs quickly into the plant stream, protecting new leaves as they grow.
-
🛡️
Complete Protection: Kills pests hiding under leaves or inside curled foliage where sprays can't reach.
-
⏳
Long-Lasting Results: A single application provides extended control, reducing the need for frequent spraying.
-
🌧️
Excellent Rainfastness: Once absorbed by the leaf (usually within hours), it cannot be washed away by rain.
-
🌿
Phytotonic Effect: Helps crops look greener and healthier, often boosting plant vigor alongside pest control.

How It Works: Mode of Action
Looper acts as a neurotoxin. It mimics natural nerve signals but blocks the "off switch" in the insect's nervous system.
- Systemic Absorption: When sprayed, the active ingredient enters the plant and travels upward (acropetally) through the xylem to stems and leaves.
- Ingestion: Sucking pests (like Aphids or Hoppers) pierce the plant to drink sap and ingest the toxin.
- Nervous System Failure: The chemical binds to receptors in the insect's nerves, causing uncontrollable shaking and paralysis. The pest stops feeding immediately and dies shortly after.
Because it moves inside the plant, it protects new growth that appears after spraying.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Jassids, Aphids, Thrips, Whitefly |
| Paddy (Rice) | Brown Plant Hopper (BPH), White Backed Plant Hopper (WBPH) |
| Vegetables (Okra/Cucumber) | Aphids, Jassids |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Because Looper is highly concentrated (70%), you only need a very small amount.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 12 - 14 g | 200 L | ~0.07 g | 20 |
| Paddy | 12 - 14 g | 200 L | ~0.07 g | 7 - 10 |
| Vegetables (Okra) | 12 - 15 g | 200 L | ~0.07 g | 3 - 5 |
*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 reaches the Economic Threshold Level (ETL). For Jassids, this is roughly 2 nymphs per leaf; for BPH, 5-10 insects per hill.
- Mixing: Premix the granules in a small mug of water to ensure they dissolve completely before adding to the main tank.
- Coverage: Ensure uniform coverage. The product will move inside the plant, but good coverage accelerates the process.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does "Looper" Insecticide kill caterpillar Loopers?
No. Despite the brand name, this product is for sucking pests only. If you need to kill Looper caterpillars, you should use Crystal Missile (Emamectin Benzoate).
2. Is this product safe for Honey Bees?
Looper (Imidacloprid) is toxic to bees. Do not spray during active flowering stages or when bees are actively foraging in the field.
3. Can I mix Looper with other products?
Yes, it is physically compatible with most fungicides and insecticides (like Missile/Emamectin) for broad-spectrum control, but avoid mixing with highly alkaline substances (like Bordeaux mixture).
4. What is the benefit of WG formulation over liquid SL?
The WG (granule) formulation is more stable in hot weather, safer to handle (no solvent smell), and requires much less product quantity per acre compared to the older liquid version.
5. Does it control Whiteflies?
Yes, Looper is effective against Whiteflies in Cotton, but it works best when used in rotation with other chemistries to prevent resistance.
