How It Works: Mode of Action
[Image of Emamectin Benzoate mode of action diagram]Apex-50 attacks the insect nervous system from two different angles, ensuring no pest survives.
- Paralysis (Emamectin Action): It locks the insect's nerve channels open, causing flaccid paralysis. The larva stops moving and eating instantly.
- Hyperexcitation (Fipronil Action): It blocks the "brakes" of the nervous system (GABA receptors), causing severe muscle spasms and rigid paralysis.
- Total Elimination: The combination of these two effects leads to the rapid death of the pest within 2 to 4 days, while crop damage stops immediately.
It acts via Contact (touching the spray) and Stomach (eating treated leaves) action.
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 | 1.25 ml | 7 Days |
| Cotton | 250 ml | 200 L | 1.25 ml | 10-15 Days |
| Vegetables | 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.
How to Apply: Best Practices
- Timing: Apply as a prophylactic spray at flower initiation, or immediately when you see the first signs of thrips or caterpillars.
- Mixing: Apex-50 is compatible with most fungicides (like Blue Copper or Azoxystrobin), allowing you to mix for disease control in the same tank.
- Coverage: Ensure full coverage of the plant foliage. For best results against Thrips, use at least 200 Liters of water per acre.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active bee foraging hours (mid-day).
Frequently Asked Questions

For a standard 15-litre knapsack sprayer, add approximately 20 ml to 25 ml of Apex-50.
3. Can I mix Apex-50 with other fungicides?
Yes, it is physically compatible with many fungicides and plant growth regulators. However, always perform a small jar test before mixing large quantities.
4. Does this product help in plant growth?
Yes, farmers often observe a "Phytotonic effect" where the crop becomes greener and healthier after spraying, thanks to the Fipronil component.
5. Is Apex-50 safe for honey bees?
The product contains Fipronil, which is toxic to bees. Avoid spraying during flowering when bees are active, or spray in the late evening to protect pollinators.
