Why Choose This Product? Key Benefits
- ⏱️Curative "Kick-Back" Action: Stops active infections up to 96 hours (4 days) after the fungus attacks, saving your crop even if you missed a preventative spray.
- ?️Triple-Action Defense: Works as a systemic protector (moves inside the plant), a curator (cures disease), and an eradicator (kills the fungus).
- ⏳Short Harvest Interval: Features a very short waiting period for Chillies (just 3 days), allowing you to harvest and sell produce quickly without residue worries.
- ?️Rainfast in 2 Hours: Rapidly absorbed into the leaf tissue within 1-2 hours, making it an excellent choice during the monsoon season.
- ?Vapor Phase Activity: After spraying, Nidar releases a vapor that reaches hidden pests inside dense canopies and tight fruit bunches where liquid sprays can't reach.

How It Works: Mode of Action
Nidar acts as a Sterol Biosynthesis Inhibitor (SBI). It specifically targets the fungal enzyme system to stop the pathogen from growing.
- Blocks Enzyme Activity: The active ingredient, Myclobutanil, binds to the fungal enzyme C14-demethylase.
- Stops Cell Wall Construction: This binding prevents the fungus from producing Ergosterol, a vital building block for the fungal cell membrane (similar to how animals need cholesterol).
- Collapse and Death: Without Ergosterol, the fungal cell walls become weak and leaky. The fungus stops feeding, collapses, and dies.

Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Apple | Scab (Venturia inaequalis) |
| Grape | Powdery Mildew (Uncinula necator) |
| Chilli | Powdery Mildew, Leaf Spot, Die-back (Fruit Rot) |
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 or g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 150 - 200 g | 500 L | 0.4 g | 3 Days |
| Apple | Based on Tree Size | 10 L / Tree | 0.4 g | 21 Days |
| Grape | Based on Canopy | 200 - 400 L | 0.4 g | 15 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 is severe) or within 96 hours of infection. Do not use late in the season for Apples (due to 21-day wait period).
- Mixing: Nidar is a Wettable Powder. Always make a "slurry" (paste) in a small bucket with water first, then add it to the main tank while stirring.
- Coverage: Ensure fine mist coverage. The vapor action will help reach the undersides of leaves and inside fruit bunches.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying when bees are actively foraging.
Frequently Asked Questions
1. Does Nidar work if it rains after spraying?
Yes. Nidar is absorbed into the plant system within 1 to 2 hours. Once absorbed, it is "rainfast" and will not wash off.
2. Can I use Nidar for Chilli fruit rot?
Yes, Nidar is highly effective against Die-back and Fruit Rot in Chillies, with the added benefit of a short 3-day waiting period before harvest.
3. Can I mix Nidar with other chemicals?
Nidar is compatible with most insecticides and fungicides like Mancozeb. However, never mix it with alkaline products like Bordeaux Mixture or Lime Sulfur.
4. How does it help with Apple Scab?
It provides systemic protection and has a "kick-back" effect, meaning it can cure early-stage scab infections if sprayed within 4 days of the rain event.
5. Should I use Nidar repeatedly?
No. To prevent resistance, limit Nidar to 2-3 sprays per season and rotate with other fungicides (like Mancozeb or Strobilurins).
