How It Works: Mode of Action
[Image of Thiamethoxam mode of action diagram]Devsena works by mimicking acetylcholine, a key transmitter in the insect nervous system. It is a systemic poison, meaning the plant absorbs it and becomes toxic to pests that try to eat it.
- Uptake: Applied to the soil or leaves, the active ingredient is quickly absorbed by roots and moves up to the stems and foliage.
- Targeting: When a pest (like a termite or hopper) ingests the sap, the chemical attacks their central nervous system receptors.
- Result: The pest suffers from hyperexcitation and tremors, stops feeding immediately, and dies shortly after.
*Note: Because it stops feeding instantly, it prevents pests from spreading viral diseases to healthy plants.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Sugarcane | Termites, Early Shoot Borer |
| Rice (Paddy) | Brown Plant Hopper (BPH), Green Leaf Hopper (GLH) |
| Cotton | Jassids, Thrips, Aphids |
| Groundnut | Termites, Soil Pests |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Devsena is a concentrated granule, so precision is key.
Dosage per Acre, Dilution, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Method | PHI (Days) |
|---|---|---|---|---|
| Sugarcane | 64 g | 200 - 400 L | Soil Drench | 230 |
| Rice (Paddy) | 60 g | N/A (Sand Mix) | Broadcast w/ 8kg Sand | 60 |
| Cotton | 50 g | 200 L | Soil Drench | 109 |
| Groundnut | 50 g | 200 - 400 L | Soil Drench | 57 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray/application and harvesting.
How to Apply: Best Practices
- Rice Strategy (Sand Mix): For Paddy, dissolve 60g of Devsena in 500ml of water first. Mix this solution with 8kg of sand and broadcast it into standing water. This reaches pests at the base of the plant.
- Sugarcane Strategy (Drenching): Apply as a soil drench along the furrows over the setts. This creates a barrier against termites attacking the roots.
- Timing: Apply during the early vegetative stage or at the first sign of pest activity for maximum "Vigor Effect" and protection.
- Safety: This product is toxic to honeybees. Avoid applying during active flowering. Always wear PPE (gloves, mask, goggles).
Frequently Asked Questions
1. What is the "Vigor Effect"?
This refers to Thiamethoxam's ability to improve plant health beyond just killing pests. It helps plants develop thicker roots, greener leaves, and better resistance to drought.
2. Is Devsena different from "Devsena 88"?
Yes. Devsena (HPM) is an insecticide. "Devsena 88" is a variety of Chilli seed. Be careful to buy the correct product for your needs.
3. Can I use it for Stem Borers?
While primarily for sucking pests, the systemic action of Devsena also provides control against Early Shoot Borers in Sugarcane and can help manage Stem Borers in rice when applied early.
4. How long does the protection last?
It offers long-duration control. In soil applications for Sugarcane, protection can persist for a significant part of the vegetative phase (PHI is 230 days).
5. Can I mix Devsena with other products?
Yes. Farmers often mix it with "HPM Gold" (Bio-fertilizer) for enhanced root growth or fungicides like "Batista" for complete crop protection.
