Item description
HPM Devsena Thiamethoxam 75% SG Systemic Insecticide
HPM Devsena is a soluble-granule systemic insecticide containing Thiamethoxam 75% w/w SG. HPM lists it for specific soil and rice-sand applications against label-listed pests in groundnut, sugarcane, rice and cotton.
Thiamethoxam belongs to the neonicotinoid class and is classified in IRAC Group 4A. It acts through contact, stomach and systemic activity on susceptible insects. Use Devsena only for the crop, pest, dose, method and waiting period stated on the current physical label.
Why Choose HPM Devsena?
- Verified formulation: Thiamethoxam 75% w/w SG from HPM Chemicals & Fertilizers.
- Systemic action: the active ingredient is taken up by the plant and acts on susceptible pests through their nervous system.
- Crop-specific directions: the official HPM product page provides separate rates and methods for groundnut, sugarcane, rice and cotton.
- Resistance classification: IRAC Group 4A makes the mode of action clear for rotation planning.

How It Works
Thiamethoxam acts on insect nicotinic acetylcholine receptors. By disrupting normal nerve-signal transmission in susceptible pests, it causes loss of control and death. Because Devsena is systemic, the method and placement on the label are important: HPM directs soil drenching for groundnut, sugarcane and cotton, and a label-specific sand-broadcast method for rice.
Thiamethoxam and other neonicotinoids share IRAC Group 4A. Another Group 4A product is a same-group substitute, not a different-mode-of-action rotation. Where a further treatment is justified, use a locally effective product from a different IRAC group whose own current label covers the same crop, pest and timing.
Target Crops & Pests
| Crop | Label-Listed Pest(s) |
|---|---|
| Groundnut | Termites |
| Sugarcane | Termites and early shoot borer |
| Rice (Paddy) | Green leafhopper and brown planthopper |
| Cotton | Jassids and thrips |
Dosage & Application Guide
Use the crop-specific rate and method. Do not convert these soil and sand-broadcast directions into a universal grams-per-litre spray dose.
| Crop | Product Rate | Official Application Medium | PHI |
|---|---|---|---|
| Groundnut | 50 g/acre | 200–400 L water/acre; soil drench as directed | 57 days |
| Sugarcane | 64 g/acre | 200–400 L water/acre; soil drench as directed | 230 days |
| Rice (Paddy) | 60 g/acre | Dissolve in 500 ml water, mix with sand at the label rate and broadcast; HPM specifies 20 kg sand/ha | 60 days |
| Cotton | 50 g/acre | Soil drench; HPM specifies 50–100 ml prepared solution per plant | 109 days |
PHI means pre-harvest interval: the minimum time between the last application and harvest. Rates and methods above are transcribed from HPM’s Devsena product page; the current physical pack label is the final authority.
Application Best Practices
- Measure the required crop-specific quantity. First mix it with a small quantity of water, then add the remaining labelled water volume with thorough agitation.
- For groundnut, sugarcane and cotton, direct the soil drench to the plant base/root zone exactly as stated on the label.
- For rice, use the label’s sand-mix broadcast method; do not substitute a foliar per-litre dose.
- Do not exceed the label rate, shorten the PHI, or extend use to unlisted crops or pests.
- Do not assume universal tank-mix compatibility. Follow both labels and qualified local guidance if a combination is being considered.
