How It Works: Mode of Action
- Systemic Absorption: Upon spraying, Ortain is rapidly absorbed by plant leaves and roots. It travels through the plant's vascular system (xylem).
- Nervous System Attack: When pests feed on the plant sap or come in contact with the spray, Acephate inhibits the Acetylcholinesterase (AChE) enzyme.
- Pest Paralysis: This blockage causes a "nerve storm" in the insect, leading to paralysis, cessation of feeding, and death.
Note: Ortain is also effective against insect eggs (ovicidal action), breaking the reproductive cycle.
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 | 300g – 400g | 200 L | 1.5g – 2g | 15 |
| Rice (Paddy) | 270g – 400g | 200 L | 1.5g – 2g | 15 |
| Safflower | 300g | 200 L | 1.5g | 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 at the first sign of pest infestation or economic threshold levels. For cotton, ensure application before heavy bollworm establishment.
- Mixing: Dissolve the powder in a small quantity of water first, then add to the main tank. WARNING: Do not mix with alkaline substances like Bordeaux mixture or Lime Sulfur, as this neutralizes the poison.
- Coverage: Ensure thorough coverage of foliage. Because it is systemic, it will protect new growth, but good initial coverage helps knockdown.
- Safety: Always wear PPE (gloves, mask, goggles). This is a fine powder—avoid inhaling dust during mixing. Wash hands thoroughly after use.

Yes. Ortain is systemic, meaning it absorbs into the plant and kills pests like Stem Borers that feed from the inside.
2. Can I mix Ortain with other fungicides?
Yes, it is compatible with most common insecticides and fungicides, provided they are not alkaline (high pH).
3. Is Ortain safe for fish?
Compared to many other organophosphates, Acephate is relatively low in toxicity to fish, making it suitable for rice paddies if standard precautions are taken.
4. What is the antidote for accidental poisoning?
In case of poisoning, the specific antidote is Atropine Sulfate, administered under medical supervision.
5. Does it have a strong smell?
Yes, Acephate has a distinct sulfur-like odor. This is normal and acts as a safety warning that the chemical is present.
