Striker Insecticide (Acephate 75% SP) by Nichino | Systemic Pest Control
Get "Double Engine" power against tough pests with Striker's dual-action formula.
Striker (Acephate 75% SP) is a premium systemic insecticide manufactured by Nichino India using Japanese technology. Unlike older, highly toxic chemicals, Striker carries the "Blue Triangle" mark, making it a safer, moderately toxic choice for farmers. It is designed to dissolve completely in water without harsh solvents, ensuring it doesn't burn delicate leaves.
It is the ultimate solution for controlling both chewing caterpillars (like Borers) and sucking pests (like Aphids and Jassids) in one shot. Because it moves inside the plant (systemic action), it kills hidden pests that sprays can't reach directly.

How It Works: Mode of Action
Striker works by attacking the insect's nervous system. It creates a "systemic storm" inside the pest.
- Systemic Entry: Once sprayed, the powder dissolves and enters the plant leaves. It travels through the plant sap (xylem), reaching even the parts you didn't spray directly.
- Bio-Activation (Kick-Back Effect): Inside the insect's body, Acephate converts into a more powerful compound called "Methamidophos." This supercharges the toxicity specifically against the pest.
- Nervous System Shutdown: It blocks the enzyme Acetylcholinesterase. This causes the insect's nerves to fire uncontrollably, leading to paralysis, "jitters," and death.
Note: Because it moves inside the leaf, it effectively kills "Leaf Folders" hiding inside folded leaves.

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) |
|---|---|---|---|---|
| Rice (Paddy) | 333g - 533g | 200 L | 1.5g - 2.5g | 15 |
| Cotton | 200g - 470g | 200 L | 1g - 2.5g | 15 |
| Safflower | 300g - 350g | 200 L | 1.5g - 2g | 15 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage refers to grams of product.
How to Apply: Best Practices
- Timing: Apply at the Economic Threshold Level (ETL)—for example, when you see 5% dead hearts in rice or initial leaf folder damage.
- Mixing: Do NOT mix Striker with alkaline fungicides like Bordeaux mixture or Copper Oxychloride. High pH destroys the medicine instantly.
- Coverage: Use approximately 200 Liters of water per acre to ensure the liquid drips down the plant and penetrates the canopy.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray during flowering to protect bees.
Frequently Asked Questions
1. Is Striker (Acephate) safe for honeybees?
No. Acephate is toxic to bees. Avoid spraying during the flowering stage of the crop or when bees are actively foraging.
2. Can I mix Striker with other pesticides?
Yes, it is generally compatible with neutral insecticides like Cypermethrin or fungicides like Mancozeb. However, strictly avoid mixing with alkaline substances like Lime Sulfur or Copper.
3. What is the difference between Striker and Asataf?
Both contain Acephate 75% SP. "Striker" is the brand name manufactured by Nichino India (Japanese technology), while "Asataf" is by Rallis. Striker is known for high purity and solubility.
4. Does Striker kill pest eggs (Ovicidal action)?
Striker is primarily effective against larvae and adults via contact and stomach action. It is not classified as a strong ovicide (egg killer).
5. Why does it smell so bad?
The strong sulfur/rotten cabbage smell is normal for Acephate. It indicates the presence of the active chemical.
