Gharda Dunky Insecticide (Buprofezin 22.5% + Diafenthiuron 27% SC)
The premium "One-Shot" solution for Whiteflies, Aphids, and Mites in Cotton and Chilli.
Gharda Dunky is a powerful combination insecticide that targets the entire lifecycle of sucking pests. By mixing an Insect Growth Regulator (Buprofezin) with a specialized energy blocker (Diafenthiuron), Dunky kills the adults you see and the nymphs you don't. Its advanced SC (Suspension Concentrate) liquid formulation ensures it spreads evenly and sticks to leaves, providing long-lasting protection even against resistant pests.
Best For: Farmers struggling with heavy Whitefly or Mite infestations in Cotton and Chilli who need a strong, curative solution.
Why Choose This Product? Key Benefits
-
⏱️
Complete Lifecycle Control: It attacks pests at every stage. Diafenthiuron knocks down adults and nymphs immediately, while Buprofezin sterilizes eggs and stops young nymphs from growing.
-
🛡️
Vapor (Gas) Action: Dunky turns into a vapor that penetrates dense canopies and reaches the underside of leaves, killing pests hiding where the spray didn't touch directly.
-
⏳
Mite & Insect Combo: Unlike ordinary insecticides, Dunky is also a potent Miticide. It cleans up Red Mites and Yellow Mites along with sucking insects, saving you the cost of a separate spray.
-
🌧️
Long Duration Protection: Because it stops the next generation from hatching or molting, your crop stays pest-free for longer compared to simple contact poisons.
-
🌿
Crop Safety: The SC formulation is water-based and safe for the plant, reducing the risk of flower drop or leaf burn when used as directed.

How It Works: Mode of Action
Dunky uses a "Dual-Site" strategy to overcome resistance. It doesn't just poison the insect; it shuts down its energy and growth systems.
- Immediate Paralysis (Diafenthiuron): This component blocks the insect's energy production (ATP synthase). The pest becomes paralyzed and stops feeding within hours. Sunlight helps activate this process.
- Growth Stop (Buprofezin): This acts as an "Insect Growth Regulator" (IGR). It stops nymphs from molting (shedding skin). If they can't molt, they die. It also makes adult females lay sterile eggs.
- Fumigant Effect: The spray releases vapors that travel inside the crop canopy, reaching pests hidden in curled leaves or flowers.
This combination ensures that the current population is wiped out and the next generation cannot survive.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whiteflies, Jassids, Thrips, Aphids |
| Chilli | Yellow Mites, Thrips, Whiteflies (Leaf Curl Complex) |
| Paddy (Rice) | Brown Plant Hopper (BPH), Green Leaf Hopper (GLH) |
Dosage & Application Guide
The Golden Rule: Use sufficient water volume (200 Liters/Acre) to ensure the contact poison covers the pest effectively.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 20 Days |
| Chilli | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 14 Days |
| Vegetables | 400 ml | 150 - 200 L | 2.0 ml | Check Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply during the morning or late afternoon. Avoid peak noon heat, but remember that sunlight helps activate the Diafenthiuron component after spraying.
- Coverage: Use a Hollow Cone Nozzle to create a fine mist. Ensure the spray reaches the undersides of the leaves where whiteflies and mites hide.
- Mixing: Shake the bottle vigorously before opening. Pre-mix the required quantity in a small bucket before adding it to the main tank.
- Safety: This product releases vapor. Always wear a mask and full-sleeved shirt to prevent inhaling fumes or skin contact. Do not spray against the wind.
Frequently Asked Questions
1. Does Dunky kill mites?
Yes. The Diafenthiuron component (27%) is excellent for controlling Yellow Mites in chilli and Red Spider Mites in other crops.
2. Can I use Dunky on vegetable crops ready for harvest?
It is not recommended for vegetables being harvested frequently (like daily okra or brinjal) due to the waiting period (PHI). It is best used in the vegetative or early flowering stage.
3. Can I mix Dunky with other tonics or fungicides?
Dunky is compatible with most common fungicides. However, avoid mixing it with highly alkaline substances (like lime). Always do a small jar test first.
4. Why is the price higher than normal sprays?
Dunky is a premium pre-mix of two advanced chemicals. It replaces the need to buy a separate insecticide and miticide, effectively doing the job of two products in one spray.
5. Is it safe for bees?
Diafenthiuron is toxic to bees. Do not spray when the crop is in full bloom and bees are active. If necessary, spray in the late evening when bees have returned to the hive.
