Gama Insecticide (Diafenthiuron 50% WP) – The Expert Solution for Sucking Pests
Manufactured by Insecticides (India) Ltd. (IIL), Gama is a premium "Pro-Insecticide" designed to break resistance in tough pests.
Are your crops suffering from Whiteflies, Aphids, or Mites that just won't die with regular sprays? Gama (Diafenthiuron 50% WP) is your answer. Unlike older poisons, Gama uses advanced chemistry that turns toxic only after the insect eats it. It stops the pest from feeding immediately and works through a unique vapor action to reach pests hiding under leaves.
Best For: Cotton, Vegetables (Cabbage, Cauliflower), Chillies, and Brinjal.
Why Choose Gama Insecticide? Key Benefits
- ⏱️Stops Feeding Instantly: The moment the pest comes in contact with Gama, it becomes paralyzed and stops eating your crop, preventing viral transmission.
- ?️Double Action (Insecticide + Acaricide): A "Two-in-One" solution that kills both insects (Whitefly, Aphids) and Mites (Red/Yellow Mites) in a single spray.
- ⏳Powerful Vapor Action: The spray turns into a vapor under sunlight, fumigating the crop canopy to kill pests hiding on the undersides of leaves.
- ?️Translaminar Movement: The medicine penetrates the leaf surface, moving from top to bottom to ensure total coverage even with imperfect spraying.
- ?The "Greening Effect": By clearing sooty mold and stopping honeydew secretion, Gama helps the plant recover, resulting in lush green leaves and better photosynthesis.

How It Works: Mode of Action
Gama is unique because it acts as a "Trojan Horse." It enters the insect's body as a relatively inactive substance but is converted into a powerful toxin by the insect's own enzymes and sunlight.
- Metabolic Activation: Once ingested or absorbed, the insect's metabolism converts the Thiourea into a toxic Carbodiimide.
- Energy Blockade: It attacks the mitochondria (the cell's power plant), inhibiting ATP synthase. This cuts off the insect's energy supply.
- Result: The pest suffers from paralysis, stops feeding immediately, and dies within 24 to 72 hours (Delayed Mortality).
Note: Because it takes time to convert, do not expect pests to drop dead instantly. They will stop moving and die slowly.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whiteflies, Thrips, Aphids, Jassids |
| Cabbage & Cauliflower | Diamondback Moth (DBM) |
| Chilli & Brinjal | Mites (Yellow Mite), Thrips, Borers |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not rely solely on "per tank" estimates.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Approx Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 240 - 300 g | 200 L | ~ 1.2 - 1.5 g | 21 - 28 Days |
| Cabbage / Cauliflower | 240 - 300 g | 150 L | ~ 2.0 g | 7 Days |
| Chilli / Brinjal | 240 g | 150 L | ~ 1.6 g | 3 - 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when you first see the pest (Economic Threshold Level). For whiteflies, this is usually 6-8 adults per leaf.
- Mixing (The Slurry Method): Never dump powder directly into a full tank. Mix the required quantity in a small bucket with water to make a creamy "slurry" first, then add to the main tank.
- Coverage: Use a Hollow Cone Nozzle to create a fine mist. This helps the "Vapor Action" work better and reach under leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active bee foraging (spray in the evening).
Frequently Asked Questions
1. Does Gama kill mites?
Yes, Gama is an excellent acaricide. It is very effective against Red Spider Mites and Yellow Mites, making it perfect for Chilli and Tea crops.
2. Can I mix Gama with other pesticides?
Gama is compatible with most neutral pesticides. However, never mix it with alkaline substances (like Bordeaux mixture or Lime Sulphur) as this will destroy the medicine instantly.
3. Why is the water volume important?
For Gama to work effectively via vapor action, the crop canopy needs to be fumigated. Using less water (e.g., 100L instead of 200L for cotton) reduces this effect and lowers control.
4. Is Gama safe for fish?
No. Gama (Diafenthiuron) is highly toxic to fish and aquatic life. Do not spray near ponds, canals, or in rice-fish farming systems.
5. How fast will I see results?
The pests stop feeding almost immediately, saving your crop from damage. However, actual death takes 24-72 hours. Do not panic if you see immobile pests on the leaf the next day; they are likely dying.
