Gharda Quartz Insecticide (Fipronil 80% WG)
The high-power, low-dose solution for Stem Borers in Rice and Thrips in Grapes.
Gharda Quartz is an advanced "Wettable Granule" (WG) insecticide containing 80% Fipronil. It is one of the most concentrated and powerful pest control products available in India. Designed for professional farmers, it delivers a massive knockout punch to resistant pests like Stem Borers, Leaf Folders, and Thrips with a very small dose per acre.
Best For: Rice and Grape farmers facing heavy pest pressure who need a strong, long-lasting solution with minimal chemical volume.
Why Choose This Product? Key Benefits
-
⏱️
Ultra-Low Dosage: Because it is 80% pure poison, you only need 40-50 grams per acre. This makes it easy to carry, store, and mix compared to heavy liquid bottles.
-
🛡️
Phytotonic Effect: Quartz has a "Greening Effect." It not only kills pests but also boosts plant growth, making leaves greener and roots stronger, which increases your final yield.
-
⏳
Long Duration Control: It provides protection for 15 to 20 days. This means fewer sprays per season and more savings on labor costs.
-
🌧️
Multi-Action Power: It works by Contact (touching the pest) and Stomach (pest eating the leaf). It also moves from the top of the leaf to the bottom (Translaminar) to kill hidden pests.
-
🌿
Advanced WG Technology: The granules dissolve instantly in water without dust. It is safer for the operator and covers the crop more evenly than old powders.

How It Works: Mode of Action
Quartz attacks the central nervous system of the insect, causing total system failure.
- Nerve Blockade: It blocks the "GABA" channels, which act as the "brakes" for the insect's nerves.
- Hyper-Excitation: Without brakes, the nerves fire uncontrollably. The insect starts shaking (tremors) and cannot control its movements.
- Paralysis & Death: The pest stops feeding almost immediately. Within hours, it becomes paralyzed and dies from exhaustion.
This mechanism works even on pests that are resistant to other chemicals like organophosphates.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Yellow Stem Borer, Leaf Folder, Brown Plant Hopper (BPH) |
| Grapes | Thrips (Scab Prevention) |
| Chilli / Onion | Thrips, Fruit Borers |
| Cabbage / Cauliflower | Diamondback Moth (DBM) |
Dosage & Application Guide
The Golden Rule: Quartz is 80% concentrated. Do not overdose. Use exactly what is recommended per acre.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 20 - 25 g | 200 L | 0.1 - 0.15 g | 19 Days |
| Grapes | 40 - 50 g | 300 - 400 L | 0.1 - 0.15 g | 15 Days |
| Chilli / Onion | 40 - 50 g | 200 L | 0.2 - 0.25 g | 7 - 15 Days |
| Cabbage | 38 - 40 g | 200 L | 0.2 g | 15 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Pre-Mixing: Always mix the required dose in a small bucket of water (2-5 Litres) first to make a "slurry." Then pour this into your main spray tank. This ensures the granules dissolve completely.
- Nozzle: Use a Hollow Cone nozzle for the best mist. This helps the spray cover both sides of the leaves where Thrips and Leaf Folders hide.
- Timing: For Rice Stem Borer, spray when you see the first signs of "Dead Heart" or egg masses. Do not wait for a full outbreak.
- Pollinator Safety: Do not spray when the crop is flowering (blooming). Quartz is highly toxic to bees. Spray in the late evening if absolutely necessary.
Frequently Asked Questions
1. How is Quartz different from Regent (Fipronil 5% SC)?
Quartz is 16 times more concentrated (80% vs 5%). This means you need a tiny amount (grams) of Quartz compared to large bottles of Regent (milliliters) to get the same or better result.
2. Does it control Brown Plant Hopper (BPH)?
Yes, it is effective against BPH in Rice. For best results, direct the spray nozzle to the base of the plant where hoppers live.
3. Can I use Quartz on Vegetables?
Yes, it is excellent for Chilli, Onion, and Cabbage. However, be careful with the waiting period (PHI) before harvest to avoid chemical residues.
4. Can I mix Quartz with Fungicides?
Yes, Quartz is compatible with most common fungicides like Hexaconazole or Propiconazole. Always do a small jar test first to be sure.
5. Is it safe for fish?
No. Fipronil is highly toxic to fish and shrimp. Do not use Quartz in paddy fields where you are farming fish, and do not let the water drain into ponds.
