Syngenta Polo Insecticide (Diafenthiuron 50% WP)
The Ultimate Solution for Resistant Sucking Pests and Whiteflies
Syngenta Polo is a broad-spectrum insecticide designed specifically to control tough sucking pests in Cotton, Vegetables, and other crops. Powered by the active ingredient Diafenthiuron, it works as a "Pro-Insecticide," meaning it activates upon contact with sunlight and inside the insect to deliver powerful results.
Why Choose This Product? Key Benefits
-
⏱️
Stops Feeding Instantly: Paralyzes pests immediately upon contact, preventing further crop damage even before the insect dies.
-
🛡️
Resistance Breaker: Highly effective against pests that have developed resistance to standard chemical groups like organophosphates and pyrethroids.
-
⏳
Translaminar Action: Penetrates the leaf surface to kill pests hiding on the underside (bottom) of the leaves where sprays often miss.
-
🌧️
Vapor Action: Releases a fumigant vapor that reaches hidden pests inside curled leaves, dense canopies, and flower buds.
-
🌿
Long-Lasting Residue: Provides extended protection for days after spraying, reducing the need for frequent re-application.

How It Works: Mode of Action
Polo works through a unique mechanism called Mitochondrial Respiration Inhibition. It cuts off the energy supply to the insect.
- Activation: After spraying, sunlight (UV rays) and the insect's own metabolism convert the chemical into its toxic form.
- Energy Block: It targets the insect's mitochondria, stopping the production of ATP (energy).
- Elimination: The pest becomes paralyzed, stops feeding immediately, and dies from starvation within 2 to 4 days.
Note: Because it turns into a gas (vapor action) in high heat, it is highly effective but requires careful handling.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whiteflies, Aphids, Thrips, Jassids |
| Cabbage | Diamond Back Moth (DBM) |
| Chilli & Brinjal | Mites, Aphids, Whiteflies, Shoot Borer |
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 (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 250 gm | 200 - 300 L | ~1 - 1.25 gm | 21 |
| Cabbage | 250 gm | 200 - 300 L | ~1 - 1.25 gm | 7 |
| Chilli | 250 gm | 200 - 300 L | ~1 - 1.25 gm | 3-6 |
*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 "Early Threshold" stage (when pests just start appearing) for best results. Do not wait for a full outbreak.
- Mixing: Use clean water. Do not mix with highly alkaline chemicals. Ensure the powder is fully dissolved.
- Coverage: Ensure uniform coverage on foliage. The product's vapor action helps cover gaps, but direct spray is best.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Warning: Avoid inhalation of spray mist, especially in hot weather, as vapors can be toxic.
Frequently Asked Questions
1. How quickly does Polo work?
Pests stop feeding almost immediately due to paralysis, but complete death occurs within 2 to 4 days.
2. Does it kill insect eggs?
Yes, Polo has ovicidal action, meaning it can kill the eggs of certain pests, helping to break the reproductive cycle.
3. Is there a specific antidote for Polo?
No, there is no specific antidote for Diafenthiuron. Treatment is symptomatic. Prevention through safety gear (masks/gloves) is critical.
4. What if it rains after spraying?
Polo requires a rain-free period of at least 6 hours to be fully effective.
5. Why is it called a "Pro-Insecticide"?
It is chemically stable in the packet but converts into its active pest-killing form when exposed to sunlight and air on the crop.
