Wishh Insecticide (Diafenthiuron 50% WP) – Expert Whitefly & Mite Control
Manufactured by Nichino India | Advanced Japanese Technology for Sucking Pests
Wishh (Diafenthiuron 50% WP) is a powerful, broad-spectrum insecticide and acaricide designed to protect your Cotton, Chilli, and Vegetable crops. Unlike older chemicals, Wishh uses a unique "energy-blocking" mechanism to stop resistant pests like Whiteflies, Aphids, Thrips, and Mites. Once sprayed, pests stop feeding immediately, preventing further damage to your crop and ensuring higher yields.

Long-Lasting Results: Provides extended protection for up to 14 days, reducing the need for frequent spraying and saving labor costs.
-
🌧️
Excellent Rainfastness: Quickly absorbs into the leaf. Remains effective even if it rains 2 to 6 hours after application.

How It Works: Mode of Action
Wishh acts as a "Pro-Insecticide," meaning it becomes a powerful toxin only after it is sprayed and exposed to sunlight or digested by the insect.
- Activation: Upon contact with sunlight or insect enzymes, it converts into a carbodiimide derivative.
- Energy Blockade: It targets the mitochondria (the power center) of the pest cells and inhibits ATP synthesis.
- Paralysis & Elimination: Deprived of energy, the pest becomes paralyzed, stops feeding instantly, and dies within days.
Note: You may see pests on the leaf for a day or two after spraying, but they are paralyzed and not causing damage.

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) |
|---|---|---|---|---|
| Cotton | 200 - 240g | 200 L | ~ 1.2g | 21 |
| Chilli & Brinjal | 240g | As Required | ~ 1.0g | 3 |
| Cabbage | 240g | As Required | ~ 1.0g | 7 |
| Cardamom | 320g | As Required | ~ 1.0g | 7 |
| Citrus | - | Full Coverage | 2.0g | 30 |
| Watermelon | 240g | As Required | ~ 1.0g | 5 |
*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 first sign of pest infestation. Avoid spraying during peak sunshine hours to protect pollinators; late afternoon is ideal.
- Mixing: Premix the required quantity in a small amount of water (Jar Test) before adding to the main tank. It is compatible with most fungicides like Copper Oxychloride.
- Coverage: Ensure thorough coverage of the underside of leaves where whiteflies and mites hide. Use hollow cone nozzles for a fine mist.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use in water bodies (toxic to fish).
