Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Power:
The high concentration of active ingredient ensures rapid paralysis of pests immediately upon contact. -
🛡️
Triple Action Formula:
Kills pests in three ways: mainly by contact, through the stomach (when eaten), and by vapor (fumigation). -
⏳
Long-Term Termite Barrier:
Binds to soil particles to create a lethal chemical zone that prevents termite entry for years. -
🌧️
Reaches Hidden Pests:
Strong fumigation (vapor) action allows the chemical to penetrate inside rice stems and soil tunnels where sprays can't reach. -
🌿
Cost-Effective Concentration:
Requires lower dosage volume per acre compared to 20% EC formulations, saving on logistics and packaging.

How It Works: Mode of Action
Predator targets the nervous system of the insect. It inhibits the enzyme Acetylcholinesterase (AChE), causing a blockage in nerve signal transmission. This leads to paralysis and rapid death of the pest.
- Contact Action: The aromatic solvent helps the toxin penetrate the insect's skin immediately upon spraying.
- Stomach Action: Essential for chewing pests (like caterpillars). When they eat a treated leaf or boll, they ingest the poison.
- Fumigation (Vapor) Action: The chemical releases toxic vapors that enter the breathing pores (spiracles) of pests hiding inside stems or soil.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Bollworm Complex (American, Spotted, Pink Bollworm) |
| Paddy (Rice) | Yellow Stem Borer, Leaf Folder |
| Building / Soil | Termites (Odontotermes obesus) |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 – 480 ml | 200 – 400 L | ~ 1.2 ml/L | 30 Days |
| Paddy (Rice) | 300 – 320 ml | 200 – 400 L | ~ 0.8 ml/L | 15 Days |
| Termite Control | See Mixing Ratio | Saturation | 10ml per 1 Litre water (1:99 Ratio) | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For crops, apply when pest population reaches the "Economic Threshold" (e.g., 5% damage). Do not spray during peak bee foraging times (mid-day).
- Mixing: For termites, use a strict 1:99 ratio (1 Litre Predator in 99 Litres water) to achieve the required 0.5% emulsion strength.
- Coverage: Use high water volume (High Volume Spray) to ensure the chemical drips down to the soil/stem where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling spray mist.
Frequently Asked Questions
1. What is the difference between Chlorpyrifos 20% and 50%?
Predator (50% EC) is much more concentrated than the standard 20% formulations. This means you need less product per acre to achieve the same lethal effect, making it more cost-efficient and powerful against resistant pests.
2. Can I use Predator for home termite control?
Yes. It is highly effective for pre-construction and post-construction termite treatment. Mix at a ratio of 1 part Predator to 99 parts water to treat foundation trenches and floors.
3. How does it kill stem borers inside the plant?
Predator has strong fumigation (vapor) action. After spraying, the chemical vapors penetrate the gap between the leaf sheath and stem, reaching the hidden larvae that contact sprays miss.
4. Is it safe for fish or pets?
No. Chlorpyrifos is toxic to fish and aquatic life. Do not use it in paddy fields that are used for fish farming (pisciculture). Keep pets away from treated areas until dry.
5. What is the antidote for accidental poisoning?
In case of poisoning, immediate medical attention is required. The specific antidotes are Atropine Sulphate (to block symptoms) and 2-PAM (to reactivate enzymes), administered by a qualified doctor.
