How It Works: Mode of Action
Spadin works through a unique double-action mechanism that targets the insect's nervous system differently than other poisons.
- Systemic & Translaminar Movement: Upon spraying, Spadin penetrates the leaf surface (Translaminar) and travels upwards through the plant stem (Systemic). This kills pests hiding under leaves or inside curled buds where sprays usually miss.
- Target Site Binding: The active ingredient binds to the nicotinic acetylcholine receptors (nAChR) in the insect's nervous system.
- Hyperexcitation & Death: It causes continuous firing of nerve impulses. The insect suffers from tremors, paralysis, stops feeding immediately, and dies shortly after.
Note: Because it binds differently than Imidacloprid, Spadin kills pests that are resistant to other chemicals.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Aphids (Sitobion avenae, Rhopalosiphum padi) |
| Cotton | Jassids (Leafhoppers), Aphids, Whiteflies |
| Chilli & Vegetables | Thrips (Scirtothrips dorsalis), Mites, Aphids |
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) |
|---|---|---|---|---|
| Wheat | 80 ml | 150 - 200 L | 0.4 - 0.5 ml | 14 Days |
| Cotton | 80 - 100 ml | 200 L | 0.5 ml | ~14 Days |
| Chilli | 80 - 100 ml | 200 L | 0.5 ml | 5 - 7 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 when you first see the pest (Economic Threshold Level). For Wheat, spray when you see 5-10 aphids per tiller.
- Mixing: Fill the tank with half the required water, add the dose of Spadin, mix well, and then fill the rest. Do not mix with highly alkaline chemicals like Bordeaux mixture.
- Coverage: Ensure the spray covers the underside of leaves where aphids and thrips hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Spadin and Delegate?
Spadin (Sulfoxaflor) is specialized for sucking pests like Aphids and Jassids. Delegate (Spinetoram) is a broad-spectrum killer for chewing pests (Bollworms) and Thrips. They are excellent rotation partners.
2. Is Spadin effective against resistant Aphids?
Yes. Spadin belongs to Group 4C (Sulfoximines), which has no cross-resistance with older chemicals like Imidacloprid (Group 4A). It kills resistant populations effectively.
3. Is Spadin safe for honeybees?
Spadin is considered highly safe for bees once the spray has dried (usually within 3 hours). It is recommended to spray early morning or late evening when bees are not foraging.
4. Can I mix Spadin with fungicides?
Yes, Spadin is compatible with most common fungicides like Tebuconazole or Propiconazole often used in Wheat for rust control.
5. What is the price of Spadin per acre?
While prices vary by region, the cost is approximately ₹700 - ₹800 per acre (based on the 80ml dose). Given its long residue (21 days), it is highly cost-effective compared to multiple sprays of generic chemicals.
