Gharda Black Insecticide (Indoxacarb 5% + Fipronil 5% SC)
The ultimate dual-action solution for hard-to-kill pests in Chilli, Cotton, and Cabbage.
Gharda Black is a premium "Suspension Concentrate" (SC) insecticide that combines two powerful chemistries: Indoxacarb and Fipronil. Designed for modern farmers, it tackles resistance issues by attacking pests in two different ways simultaneously. Whether you are fighting Thrips in Chilli or Diamondback Moths (DBM) in Cabbage, Black provides a complete "Knockdown + Long Duration" defense strategy.
Best For: Farmers facing pest resistance who need a safe, water-based liquid formulation that won't burn leaves.
Why Choose This Product? Key Benefits
-
⏱️
Quick Knockdown Power: The Fipronil component acts immediately on contact, causing rapid paralysis of the pest. You see results fast.
-
🛡️
Double Engine Action: It targets chewing pests (caterpillars) and sucking pests (thrips/jassids) at the same time, saving you the cost of mixing two sprays.
-
⏳
Stops Feeding Instantly: Thanks to Indoxacarb, pests stop damaging your crop within minutes of eating the treated leaf, even if they die later.
-
🌧️
Rain & Wash-Off Resistance: Once the spray dries (approx. 2-4 hours), the SC formulation sticks firmly to the leaf, reducing wastage during monsoon spells.
-
🌿
Crop Safety (No Leaf Burn): Unlike oil-based sprays (EC), this water-based SC formula is gentle on flowers and tender leaves, preventing phytotoxicity.

How It Works: Mode of Action
'Black' uses a unique "Dual-Site" strategy to kill pests that are resistant to other chemicals. It attacks the insect's nervous system from two different angles.
- Nerve Block (Indoxacarb): It blocks the Sodium Channels in the nerve cells. This causes immediate paralysis and the "Stop-Feeding" effect. The larva may look alive for a day, but it cannot eat your crop.
- Hyper-Excitation (Fipronil): It blocks the GABA receptors (the "brakes" of the nerve system). This causes the pest's nerves to fire uncontrollably, leading to tremors and rapid death.
- Hidden Pest Control: Fipronil moves "translaminarly" (from top to bottom of the leaf), killing thrips hiding on the underside of leaves where the spray didn't reach directly.
This combination breaks the resistance cycle of pests like DBM and Bollworms.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli | Thrips, Fruit Borer (Helicoverpa), Aphids |
| Cabbage & Cauliflower | Diamondback Moth (DBM), Caterpillars |
| Cotton | Bollworm Complex, Jassids, Whiteflies |
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) |
|---|---|---|---|---|
| Chilli | 350 - 400 ml | 200 L | 2.0 ml | 5 Days |
| Cabbage | 350 - 400 ml | 200 L | 2.0 ml | 7 Days |
| Cotton | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | - |
*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 "Economic Threshold Level" (ETL)—when you first see 5-10 thrips per leaf or early caterpillar damage. Do not wait for a full outbreak.
- Mixing: Shake the bottle well before use. Pre-mix the required dose in a small bucket of water before adding it to your main spray tank.
- Coverage: Use a Hollow Cone Nozzle for the best mist. Ensure the spray covers the underside of the leaves where thrips and DBM larvae hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying when bees are active (mid-day).
Frequently Asked Questions
1. Does 'Black' kill sucking pests other than Thrips?
Yes. Due to the Fipronil content, it is also highly effective against Jassids (Leafhoppers) and Whiteflies, particularly in cotton crops.
2. Can I mix this with fungicides?
Yes, it is compatible with most common fungicides like Mancozeb or Carbendazim. However, do not mix it with highly alkaline products like Bordeaux mixture.
3. What if it rains after spraying?
The product needs about 2-4 hours to dry and set on the leaf. If it rains heavily within an hour of spraying, efficacy may be reduced, and you might need to check pest levels after 2 days.
4. Can I use this in my home kitchen garden?
No. This is a professional agricultural product with moderate toxicity. It is not recommended for casual home gardening where children or pets might be present.
5. How does it help with resistance management?
Because it attacks two different parts of the insect's body (Nerve channel + GABA receptor), it kills pests that might be resistant to ordinary poisons. It is an excellent tool to rotate with Coragen or Emamectin.
