How It Works: Mode of Action
Asataf acts as a neurotoxin that specifically targets the insect's nervous system.
- Systemic Absorption: When sprayed, the plant absorbs the chemical through leaves and roots. It travels through the plant's vascular system, making the plant juices toxic to pests.
- Enzyme Inhibition: It blocks the production of Acetylcholinesterase (AChE), a vital enzyme in the insect's nervous system.
- Paralysis & Death: The pest's nerves fire uncontrollably, leading to paralysis, cessation of feeding, and eventual death.
This mechanism makes it highly effective against insects that suck sap (like Aphids) or bore inside stems (like Stem Borers), where contact sprays cannot reach.
Target Crops & Pests

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) |
|---|---|---|---|---|
| Cotton | 300 - 312g | 150 - 200 L | 1.5 - 2.0 g | 15 |
| Paddy (Rice) | 266 - 400g | 150 - 200 L | 1.5 - 2.0 g | 15 |
| Safflower | 312g | 200 L | 1.5 g | 15 |
*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 pest infestation reaches the Economic Threshold Level (e.g., 5% dead hearts in Paddy).
- Mixing: **IMPORTANT:** Do NOT mix Asataf with alkaline fungicides like Bordeaux mixture or Copper Oxychloride. This destroys the chemical.
- Coverage: Ensure the spray reaches the undersides of leaves where pests like Jassids hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
