The Ultimate Systemic Protection Against Sucking Pests for Rice, Cotton, and Vegetables.
Actara Insecticide by Syngenta is a world-class, second-generation neonicotinoid designed to control tough sucking pests and soil-dwelling insects. Powered by Thiamethoxam (25% WG), it doesn't just kill pests; it absorbs quickly into the plant, providing long-lasting protection from the inside out.
Why Farmers Trust Actara: Beyond pest control, Actara offers the unique "Thiamethoxam Vigor Effect." It helps plants withstand stress, resulting in greener leaves, stronger roots, and better yields even in difficult weather conditions.

- ?️Systemic Power: Absorbed by roots and leaves, it moves upward to protect new growth that wasn't even sprayed.
- ⏳Long-Lasting Control: Forms a reservoir within the leaf, providing residual protection for 14 to 21 days.
- ?️Rainfast: Absorbs quickly into the plant system; it is effective even if it rains 2 hours after spraying.
- ?Crop Vigor Effect: Acts as a bio-stimulant, making plants greener, healthier, and more resistant to drought.

How It Works: Mode of Action
Actara works on the insect's central nervous system. It mimics acetylcholine (a nerve transmitter) but cannot be broken down by the insect's enzymes. This causes continuous nerve stimulation.
- Absorption: Upon spraying, the granules dissolve and are rapidly absorbed by the plant surface or roots.
- Translocation: The active ingredient travels upwards through the xylem (water vessels), reaching every leaf and stem.
- Elimination: When pests suck the sap, the chemical blocks their nerve signals. This leads to paralysis, cessation of feeding, and death within 24-48 hours.
Note: Its "Translaminar" property allows it to pass through the leaf to the underside, killing pests hiding there.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), Green Leaf Hopper, Stem Borer |
| Cotton | Jassids, Aphids, Whiteflies, Thrips |
| Vegetables (Tomato, Okra, Brinjal) | Whiteflies, Aphids, Jassids, Leaf Miners |
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 (Paddy) | 40 - 80g | 200 L | 0.2 - 0.4g | 14 Days |
| Cotton | 40 - 100g | 200 L | 0.2 - 0.5g | 21 Days |
| Vegetables (Tomato/Okra) | 40 - 80g | 200 L | 0.2 - 0.4g | 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: Spray in the early stages of pest infestation (ETL stage). Apply in the evening to protect pollinators and reduce evaporation.
- Mixing: Premix the granules in a small bucket of water first, then add to the main tank. It disperses easily.
- Coverage: Use a Hollow Cone Nozzle for the best mist. For Rice, aim spray at the base of the plant for BPH control.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during full bloom to save bees.
Frequently Asked Questions
1. What is the "Vigor Effect" in Actara?
Actara acts as a bio-stimulant. It triggers stress-defense proteins in the plant, helping it grow thicker stems, greener leaves, and stronger roots, even in dry or salty conditions.
2. Can I use Actara for Brown Plant Hopper (BPH) in Rice?
Yes, it is highly effective against BPH. However, ensure you spray at the base of the stem where the hoppers hide and use sufficient water (200L/acre).
3. Is Actara compatible with other fungicides?
Yes, it is physically compatible with common fungicides like Mancozeb and Carbendazim. Do NOT mix with highly alkaline products (like Bordeaux mixture).
4. How soon can I harvest after spraying?
It depends on the crop (see table above). For vegetables like Tomato and Okra, the waiting period is short (5 days). For Rice, it is 14 days.
5. Is this safe for Honeybees?
Thiamethoxam is toxic to bees. Avoid spraying when the crop is flowering or when bees are actively foraging. Evening spraying is safer.
