Crystal Apex-50 Insecticide (Emamectin Benzoate 1.5% + Fipronil 3.5% SC)
The "One-Shot" Solution for Thrips and Fruit Borers in Chilli and Cotton.
Crystal Apex-50 is a premium, broad-spectrum insecticide designed to protect your high-value crops. By combining two powerful active ingredients—Emamectin Benzoate and Fipronil—it delivers a "Synergistic" effect. This means it controls both sucking pests (like Thrips) and chewing pests (like Caterpillars) in a single spray, saving you labor costs and boosting crop quality.

How It Works: Mode of Action
Apex-50 attacks the insect nervous system from two different angles, making it nearly impossible for pests to survive or develop resistance.
- Double Attack Strategy: It works via Contact (when pests touch the spray) and Stomach action (when pests eat treated leaves).
- Muscle Paralysis (Emamectin): It locks the insect's chloride channels open, causing flaccid paralysis. The larva stops moving and feeding immediately.
- Nerve Hyperexcitation (Fipronil): It blocks GABA channels, removing the nervous system's "brakes." This causes severe convulsions and rapid death of the pest.
This combination effectively kills adults, larvae, and even damages eggs (Ovi-larvicidal action), breaking the pest reproductive cycle.
Target Crops & Pests

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) |
|---|---|---|---|---|
| Chilli | 200 - 250 ml | 200 L | 1.0 - 1.25 ml | 7 Days |
| Cotton | 200 - 250 ml | 200 L | 1.0 - 1.25 ml | 7 - 10 Days |
| Cabbage / Tomato | 200 ml | 200 L | 1.0 ml | 3 - 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residue safety.
How to Apply: Best Practices
- Timing: Apply as a prophylactic spray at flower initiation or when pest population crosses the Economic Threshold Level (e.g., 5-10 thrips per leaf).
- Mixing: Compatible with most fungicides (like Blue Copper or Azoxystrobin), allowing for comprehensive "Crop Health" sprays.
- Coverage: Use sufficient water (200 Litres/Acre). Ensure the underside of leaves is sprayed, as this is where thrips hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active bee foraging hours (mid-day).
