Nidar Fungicide (Myclobutanil 10% WP)
The Expert Solution for Apple Scab, Powdery Mildew, and Chilli Die-back.
Nidar (by HPM Chemicals) is a powerful systemic fungicide designed to protect your high-value crops like Apple, Grapes, and Chillies. Powered by Myclobutanil, it doesn't just sit on the leaf surface—it penetrates the plant to cure hidden fungal infections from the inside out.
Whether you are battling Apple Scab in the hills or Powdery Mildew in the plains, Nidar offers reliable "kick-back" action, stopping disease even after infection has started.

How It Works: Mode of Action
Nidar works as a Sterol Biosynthesis Inhibitor (SBI). [Image of fungal cell membrane disruption diagram]
- Absorption: Upon spraying, the active ingredient is quickly absorbed by the leaves and enters the plant's water transport system.
- Blockage: It targets the fungus and blocks the production of "Ergosterol," a vital nutrient needed to build fungal cell walls.
- Elimination: Without strong cell walls, the fungus stops growing, the infection tube collapses, and the pathogen dies.
Note: This systemic action ensures that the fungus is killed even if it has already penetrated the leaf surface.
Target Crops & Pests

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 (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 150 - 200 g | 500 L | 0.4 g | 3 Days |
| Grape | 200 - 400 g | 500 - 1000 L | 0.4 g | 15 Days |
| Apple | Specific to Tree Age | 10 L / Tree | 0.4 g | 21 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 preventively (before disease starts) or within 96 hours of infection for curative action. For apples, apply at the Pink Bud stage.
- Mixing: Do not dump the powder directly into the tank. First, mix Nidar with a little water in a bucket to make a smooth slurry, then add it to the spray tank.
- Coverage: Ensure a fine spray mist. The vapor action will help cover hard-to-reach areas, but good physical coverage is key.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying against the wind.
Frequently Asked Questions
1. Can I use Nidar on Chillies just before harvest?
Yes! Nidar has a very short waiting period of only 3 days for Chilli, making it safe and convenient for continuous harvesting.
2. Does Nidar wash off if it rains?
Nidar is rainfast within 1 to 2 hours. Once it is absorbed by the plant, rainfall or irrigation will not reduce its effectiveness.
3. Can I mix Nidar with other products?
Yes, Nidar is compatible with most common insecticides and fungicides like Mancozeb and Sulfur. However, do not mix it with alkaline products like Bordeaux Mixture.
4. What is the "Kick-Back" action?
Kick-back means curative action. If a fungus infects your plant, Nidar can stop and kill that infection if applied within 4 days (96 hours).
5. How do I prevent resistance in Apple Scab?
Do not rely solely on Nidar. Rotate it with other fungicides and tank-mix it with a contact fungicide like Mancozeb to prevent resistance build-up.
