How It Works: Mode of Action
Actara works by targeting the nervous system of the insect. It is a nicotinic acetylcholine receptor (nAChR) agonist.
[Image of neonicotinoid mode of action diagram]- Lock and Key: The active ingredient mimics the insect's natural nerve signals and binds irreversibly to their nerve receptors.
- Feeding Cessation: Once the chemical hits the system, the insect becomes hyper-excited, paralyzed, and immediately stops feeding on your crop.
- Elimination: Unable to feed or move, the pest dies within 24 to 48 hours.
Note: This mechanism effectively breaks the life cycle of pests and prevents the transmission of viral diseases by vectors like Whiteflies.

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) |
|---|---|---|---|---|
| Rice | 40 - 80 g | 200 L | 0.2 - 0.4 g | 14 Days |
| Cotton | 40 - 100 g | 200 L | 0.4 - 0.5 g | 21 Days |
| Vegetables (Tomato/Brinjal) | 40 - 80 g | 150 - 200 L | 0.3 - 0.4 g | 3 - 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Since Actara is a solid granule, dosage is measured in grams (g), not ml.
How to Apply: Best Practices
- Timing: Apply at the first sign of pests (Economic Threshold Level). For Rice, apply when you see 5-10 hoppers per hill.
- Mixing: Premix the required quantity of granules in a small amount of water to make a slurry before adding to the main tank. Do NOT mix with alkaline products like Bordeaux mixture.
- Coverage: Ensure good coverage of the foliage. For Rice, aim the spray nozzle at the base of the plant where hoppers reside.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during flowering to protect bees.
Frequently Asked Questions
1. Is Actara safe for bees?
Actara is toxic to bees. Do not spray on crops when they are in full bloom or when bees are actively foraging. Spray in the early morning or late evening.
2. Can I mix Actara with fungicides?
Yes, Actara is compatible with many common fungicides like Amistar Top or Ridomil Gold. However, always perform a small "jar test" first and avoid mixing with alkaline substances.
3. What if it rains after I spray?
Actara is rainfast within 2 to 3 hours. If it rains after this period, you do not need to re-spray.
4. Does it control Stem Borer in Rice?
Yes, due to its systemic nature, Actara is effective against Stem Borers and helps prevent "Dead Heart" symptoms when applied at the correct stage.
5. How is the WG formulation better than powder?
The WG (granule) formulation is safer as it does not create dust while mixing. It dissolves easily in water and ensures accurate dosing compared to powders.
