UPL Gunther Insecticide (Novaluron 5.25% + Emamectin Benzoate 0.9% SC)
The "Double-Action" Specialist for Controlling Resistant Caterpillars and Borers.
UPL Gunther Insecticide is a premium, broad-spectrum solution designed to fight the toughest pests in Indian agriculture. By combining two powerful active ingredients—Novaluron and Emamectin Benzoate—it offers a unique "Double Attack" mechanism. It doesn't just kill the visible larvae; it breaks the pest's life cycle by destroying eggs and preventing growth. Whether you are growing high-value crops like Chilli and Cotton or staples like Rice, Gunther ensures rapid knockdown and long-lasting protection against fruit borers, stem borers, and "super pests" like the Diamondback Moth.
Why Choose This Product? Key Benefits
- ⏱️Rapid Knockdown Action: Stops caterpillars from feeding within hours of spraying, preventing further crop damage immediately.
- ?️Complete Life Cycle Control: Acts as a "Double Attack" by killing feeding larvae (neurotoxin) and destroying eggs (ovicidal action).
- ⏳Long-Lasting Protection: Remains active on the leaf surface and inside the tissue, reducing the need for frequent re-spraying.
- ?️Excellent Rainfastness: The SC (Suspension Concentrate) formulation sticks well to leaves, ensuring efficacy even in challenging weather.
- ?Hidden Pest Control: Translaminar action penetrates the leaf, killing pests hiding on the underside or boring into the plant.

How It Works: Mode of Action
[Image of insect metamorphosis or life cycle]
- The "Hammer" (Emamectin Benzoate): It attacks the pest's nervous system, causing paralysis. The larva stops eating almost immediately, saving your crop from further bite marks.
- The "Anvil" (Novaluron): It acts as an Insect Growth Regulator (IGR). It stops the larva from forming new skin (chitin), causing it to die when it tries to molt or grow.
- Resistance Breaking: Because it attacks the pest in two different ways simultaneously, it is highly effective against pests that have become resistant to ordinary sprays.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli & Tomato | Fruit Borer (Helicoverpa), Tobacco Caterpillar |
| Cabbage & Cauliflower | Diamondback Moth (DBM), Leaf eating caterpillars |
| Rice (Paddy) | Stem Borer (Yellow Stem Borer), Leaf Folder |
| Cotton & Red Gram | Bollworms, Pod Borers |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Rice requires a higher dose than vegetables.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Vegetables (Chilli, Cabbage) | 350 ml | 200 L | 1.8 ml | 5 - 7 Days |
| Pulses (Red Gram) | 350 ml | 200 L | 1.8 ml | 14 Days |
| Rice (Paddy) | 600 ml | 200 L | 3.0 ml | 25 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when you see 1-2 larvae per plant (Economic Threshold Level). For Stem Borer in Rice, apply as a rescue spray if dead hearts are visible.
- Mixing: Fill the tank half with water, add the measured dose of Gunther, mix well, and then fill the rest. Compatible with common fungicides like Carbendazim.
- Coverage: Use a hollow cone nozzle to create a fine mist. Ensure the spray covers both the top and bottom of the leaves for maximum "translaminar" effect.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during peak sunlight hours to protect bees.
Frequently Asked Questions
1. Does Gunther kill eggs?
Yes. The Novaluron component provides strong ovicidal action, meaning it destroys pest eggs before they can hatch, breaking the reproductive cycle.
2. Is Gunther safe for vegetables?
Yes. It is highly effective for Chilli, Tomato, and Cabbage. It has a relatively low PHI (Pre-Harvest Interval), making it suitable for crops that are harvested frequently.
3. Can I use it on Rice for Stem Borer?
Absolutely. While granular insecticides (like Ferterra) are good for prevention, Gunther is an excellent curative spray to stop active infestation. Note: Rice requires a higher dosage (600 ml/acre).
4. How soon will the pests stop eating?
Due to the Emamectin Benzoate, larvae undergo paralysis and stop feeding within a few hours of application, minimizing crop loss immediately.
5. What is the pack size available?
The product is commonly available in 250 ml (ideal for small plots), 500 ml, and 1 Litre bottles.
