Asataf Insecticide (Acephate 75% SP) by Rallis India
The trusted "Blue Triangle" solution for sucking pests and bollworms in Cotton and Paddy.
Asataf (Acephate 75% SP) is a broad-spectrum, organophosphate insecticide manufactured by Rallis India (Tata Enterprise). Unlike standard sprays that only kill what they touch, Asataf works from the inside out. It is a highly soluble powder that is easily absorbed by plant roots and leaves, moving systematically to kill hidden pests like stem borers and leaf folders that other sprays miss.
Why Choose Asataf? Key Benefits
- ⏱️Rapid Action: Dissolves instantly in water without needing stirring, ensuring a uniform spray that hits pests hard.
- ?️Dual Power Protection: Combines Systemic action (internal protection) with Contact action (immediate knockdown) for total control.
- ⏳Deep Reach: Penetrates plant tissues to kill insects hiding on the underside of leaves (like Jassids) or inside stems (like Borers).
- ?️Crop Safety: As a water-soluble powder, it contains no harsh solvents, making it safe for sensitive crops and preventing leaf burn.
- ?Eco-Conscious: Relatively safe for fish in rice paddies and leaves less visible residue on vegetables compared to other powders.

How It Works: Mode of Action
- Systemic Absorption: Upon spraying, Asataf is rapidly absorbed by the plant's cuticle and roots. It travels through the plant's vascular system, turning the plant itself into a "toxic shield" against chewing and sucking pests.
- Nervous System Shutdown: Asataf targets the insect's nervous system by inhibiting the Acetylcholinesterase (AChE) enzyme.
- Paralysis and Control: This causes continuous nerve firing, leading to tremors, paralysis, and the eventual death of the pest. It acts as both a stomach poison (when eaten) and a contact poison (when touched).

Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Jassids, Bollworms (American & Spotted) |
| Paddy (Rice) | Stem Borer, Leaf Folder, Brown Plant Hopper (BPH), Green Leaf Hopper (GLH) |
| Safflower & Vegetables | Aphids, Thrips, Whiteflies |
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 - 400g | 150 - 200 L | 2g | 15 |
| Paddy (Rice) | 300 - 500g | 150 - 200 L | 2 - 2.5g | 15 |
| Vegetables | 300g | 150 L | 1.5 - 2g | 15 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage in table updated to Grams (g) as Asataf is a powder.
How to Apply: Best Practices
- Timing: Apply when pest population reaches the Economic Threshold Level (ETL). Avoid spraying during active flowering to protect honeybees.
- Mixing: Asataf mixes well with Pyrethroids (like Cypermethrin). WARNING: Do NOT mix with alkaline products like Bordeaux mixture or Copper Oxychloride, as this destroys the chemical.
- Coverage: Ensure thorough coverage of foliage. Because it is systemic, it will move inside the plant, but good initial coverage speeds up control.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.

3. Can I use Asataf for all vegetables?
It is effective for many vegetables like Brinjal and Chillies. However, always check the specific PHI (waiting period) to ensure residues are gone before harvest.
4. Can it kill eggs (ovicidal action)?
Yes, Asataf has some ovicidal properties, meaning it can reduce the hatching of pest eggs, helping to control future generations.
5. What is the antidote for Asataf poisoning?
In case of accidental poisoning, the specific antidote is Atropine Sulfate, often used in conjunction with 2-PAM. Always seek immediate medical help.
