Gharda Jhumru Insecticide (Fipronil 4% + Thiamethoxam 4% SC)
The "Crop Health" expert that stops both chewing and sucking pests.
Gharda Jhumru is a premium dual-action insecticide that combines the power of Fipronil and Thiamethoxam. This specialized "Suspension Concentrate" (SC) not only clears pests like Brown Plant Hoppers (BPH) and Stem Borers but also provides a unique "Vigor Effect" that makes your crop greener and healthier, even under stress.
Best For: Farmers growing Paddy, Cotton, and Vegetables who want to control mixed pest attacks while boosting plant growth and root health.
Why Choose This Product? Key Benefits
-
⏱️
Double Attack: It hits the insect's nervous system in two ways. Fipronil acts on contact (surface), while Thiamethoxam moves inside the plant (systemic) to kill hidden pests.
-
🛡️
The "Vigor Effect": The Thiamethoxam component actively boosts plant health, resulting in greener leaves, stronger roots, and better stress tolerance (drought/heat).
-
⏳
Long Duration Control: The systemic action provides protection for 14-21 days, reducing the need for frequent sprays and saving labor costs.
-
🌧️
Rainfast in 2 Hours: The advanced SC formulation sticks quickly to the leaf surface. Once dried (approx. 2 hours), it resists washing off by rain.
-
🌿
Safe for Crops: Being water-based, Jhumru is safe for tender leaves and flowers. It does not cause the leaf burn often seen with solvent-based sprays.

How It Works: Mode of Action
Jhumru stops pests using a "Hammer and Anvil" strategy, attacking two different parts of the nervous system.
- Nerve Block (Fipronil): It blocks the insect's "GABA" channels (the nervous system's brakes). This causes uncontrolled tremors and rapid paralysis upon contact.
- Nerve Overload (Thiamethoxam): It mimics a nerve stimulant that cannot be switched off. This over-excites the nerves, leading to exhaustion and death. It also travels systemically to new leaves.
- Root & Shoot Protection: Thiamethoxam is absorbed by roots and leaves, moving upwards to protect new growth that appears after spraying.
This combination breaks the resistance of pests that have survived single-chemical sprays.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), Stem Borer, Leaf Folder |
| Cotton | Aphids, Jassids, Thrips, Whiteflies |
| Sugarcane | Termites (Soil Drench), Early Shoot Borer |
| Vegetables (Chilli/Tomato) | Thrips, Fruit Borer (Suppression), Whitefly |
Dosage & Application Guide
The Golden Rule: Use sufficient water volume (200 Liters/Acre) to ensure the systemic medicine reaches the entire plant.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 21 Days |
| Cotton | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 21 Days |
| Vegetables | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 7 - 10 Days |
| Sugarcane (Drench) | 500 - 600 ml | 300 L | 2.0 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Rice (BPH Control): Direct the spray nozzle towards the base of the plant (just above water level) where hoppers hide. Ensure good coverage.
- Sugarcane (Termites): Mix in water and drench the furrows over the setts. This creates a chemical barrier in the soil that kills termites on contact.
- Pollinator Safety (Critical): Do not spray during peak flowering time (morning). Both active ingredients are toxic to bees. Spray in the late evening (dusk) if necessary.
- Mixing: Shake the bottle well. Mix the required dose in a small bucket first, then pour into the spray tank. Use hollow cone nozzles for best mist.
Frequently Asked Questions
1. How is Jhumru different from normal Fipronil?
Normal Fipronil is mainly a contact poison. Jhumru adds Thiamethoxam, which is systemic (moves inside the plant) and boosts plant growth (Greenness). It is a complete health package.
2. Does it control Stem Borers in Rice?
Yes. It controls Stem Borers effectively if applied during the early stages (egg hatching/larval movement). It also controls Leaf Folders simultaneously.
3. Can I use Jhumru for Termites in buildings?
No. This agricultural formulation is designed for crops. Use specialized termite control products for construction purposes. However, it is excellent for soil termites in agriculture.
4. What is the "Vigor Effect"?
The Thiamethoxam in Jhumru triggers stress-defense proteins in the plant. This makes the leaves look greener, roots grow stronger, and helps the plant withstand drought better.
5. Is it safe for fish?
No. Fipronil is highly toxic to fish and shrimp. Do not use Jhumru in paddy fields where you are farming fish, and do not let the water drain into ponds.
Safety & Disclaimer
