Syngenta Pegasus® Insecticide (Diafenthiuron): Complete Guide
The ultimate specialist for controlling Whiteflies, Diamondback Moths, and Mites in cotton and vegetable crops.
Syngenta Pegasus® is a unique "pro-insecticide" powered by the active ingredient Diafenthiuron. Unlike standard poisons, it remains inactive until it is sprayed and hit by sunlight. Once activated, it delivers a powerful "vapor action" that reaches pests hidden deep in the crop canopy.
Best Used For: Breaking resistance in tough sucking pests and mites that no longer respond to ordinary chemicals.
Why Choose This Product? Key Benefits
- ⏱️Immediate "Stop-Feeding" Action: Pests are paralyzed instantly upon contact. Although they may look alive for a few days ("Hidden Knockdown"), they cannot eat or damage your crop.
- ?️Breaks Resistance (Group 12A): Excellent for controlling pests that have developed immunity to pyrethroids and organophosphates.
- ⏳Vapor Action & Translaminar Reach: It turns into a vapor to fumigate the canopy and penetrates through the leaf to kill pests hiding on the underside.
- ?️Excellent Rainfastness: Once the spray dries (approx. 6 hours), it binds to the leaf wax and resists washing off by rain.
- ?Beneficial Insect Friendly: Safe for predatory mites and lacewings, making it a great fit for Integrated Pest Management (IPM).

How It Works: Mode of Action
Pegasus works by attacking the insect's energy system. It is unique because it requires sunlight to "switch on."
- Sunlight Activation: The chemical is inactive in the bottle. Once sprayed, UV light converts it into its toxic form.
- Energy Blockade: It inhibits mitochondrial ATP synthase. Simply put, it cuts off the power supply to the insect's cells.
- Paralysis & Starvation: The pest becomes paralyzed and stops feeding immediately. Death occurs within a few days due to energy loss.
Note: Because it needs sunlight, the "kill" is not instant, but crop damage stops instantly.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whiteflies, Aphids, Thrips, Jassids |
| Cabbage & Cauliflower | Diamondback Moth (DBM), Aphids |
| Chilli, Brinjal, Tomato | Mites (Red & Yellow), Whiteflies, Thrips |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure high water volume for dense canopies.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 240 g | 200 - 400 L | 0.6 - 1.2 g | 21 Days |
| Cabbage / Cauliflower | 240 g | 200 - 400 L | 0.6 - 1.2 g | 7 Days |
| Brinjal / Chilli | 240 g | 200 - 400 L | 0.6 - 1.2 g | 3 - 6 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residue safety.
How to Apply: Best Practices
- Timing: Spray in the EVENING. This protects honeybees (pollinators) and allows the residue to dry. Sunlight the next morning activates the chemical.
- Mixing: Ensure water pH is balanced. Do not mix with strongly alkaline products. Use plenty of water to drench the foliage.
- Coverage: Use a Hollow Cone nozzle to create a fine mist. This ensures the chemical reaches the underside of leaves where whiteflies hide.
- Safety: Always wear PPE (gloves, mask, goggles). Inhalation of the spray mist is dangerous—cover your nose and mouth strictly.
Frequently Asked Questions
1. Does Pegasus kill mite eggs?
Yes, Pegasus has ovicidal action, meaning it can kill the eggs of mites, breaking the reproductive cycle more effectively than adult-only killers.
2. Why don't the insects die immediately after spraying?
Pegasus causes immediate paralysis ("Stop-Feeding"), but death takes a few days. If the pest isn't moving or eating, the product is working.
3. Is it safe for honeybees?
It is toxic to bees when wet. However, if you spray in the evening, it dries overnight and becomes much safer for bees foraging the next morning.
4. Can I repeat the spray?
Do not apply more than 2 times per season. Rotate with other chemical groups to prevent pests from building resistance.
5. What should I do if I inhale the spray?
Seek medical help immediately. Symptoms include breathlessness and nausea. There is no specific antidote; treatment is symptomatic. Always use a mask.
