Why Choose This Product? Key Benefits
-
⏱️
Double Action Power: Acts as both a Preventive (stops disease before it starts) and a Curative (stops disease after infection) solution.
-
🛡️
Systemic Protection: Absorbed by roots and leaves, it moves internally to protect new growth that wasn't even sprayed.
-
⏳
Cost-Effective: Offers a high Return on Investment (ROI) for farmers, costing significantly less per acre than newer chemistries.
-
🌧️
Weather Resistant: Becomes rainfast within 2-3 hours of application due to strong surface adhesion.

How It Works: Mode of Action
Bavistin targets the fungal cell's ability to divide. It is absorbed rapidly by the plant's roots and leaves and travels upward (acropetally) through the xylem.
- Absorption: The active ingredient penetrates the plant tissue and seed coat.
- Targeting: It binds to beta-tubulin proteins within the fungal cell.
- Action: It inhibits mitosis (cell division), effectively stopping the development of germ tubes and mycelial growth.
This creates a toxic environment for the fungus inside the plant, eradicating existing infections and preventing new spores from establishing.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Blast (Leaf & Neck), Sheath Blight |
| Wheat & Barley | Loose Smut (Seed Treatment is best) |
| Vegetables (Tomato, Chilli, Brinjal) | Early Blight, Anthracnose, Fruit Rot, Powdery Mildew, Wilt (Drenching) |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 250 - 500 g | 150 - 200 L | 1.5 - 2.5 g | 30 - 60 |
| Vegetables (Tomato/Chilli) | 150 - 300 g | 150 - 200 L | 1.0 - 2.0 g | 3 - 7 |
| Fruits (Apple/Grape) | Based on Tree Size | High Volume | 0.5 - 1.0 g | 7 - 14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For best results, spray preventively or at the very first sign of disease. For Loose Smut in wheat, use only as a Seed Treatment before sowing.
- Mixing: Do not dump the powder directly into the full tank. Pre-mix the required quantity in a small bucket of water to make a smooth slurry ("creaming"), then add to the main tank.
- Coverage: Ensure thorough coverage of the foliage. While it is systemic, good coverage improves uptake.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Bavistin on Basmati Rice?
Currently, several states (like Punjab and UP) may have temporary bans on Carbendazim for Basmati rice during export seasons due to strict MRL limits in the EU/USA. Always check your local agriculture advisories before using on export-bound crops.
2. Is Bavistin effective for Root Rot or Wilt?
Yes. For soil-borne diseases like Wilt (Fusarium) in tomatoes or brinjal, use Bavistin as a Soil Drench (dissolve 1-2g per liter and pour around the root zone).
3. Can I mix Bavistin with other pesticides?
Yes, it is generally compatible with most insecticides (like Imidacloprid) and other fungicides (like Mancozeb). Do not mix with alkaline substances like Bordeaux Mixture or Lime Sulphur.
4. How do I use it for Seed Treatment?
For crops like Wheat, Paddy, or Cotton, mix 2g of Bavistin per 1kg of seeds. Add a little water to form a slurry to ensure uniform coating on the seeds.
5. What is the shelf life of the product?
When stored in a cool, dry place in its original unopened packaging, Bavistin typically has a shelf life of 2 years.
