How It Works: Mode of Action
Bavistin works by targeting the cell division process of the fungus. Here is the step-by-step mechanism:
- Absorption: Upon spraying, the active ingredient (Carbendazim) is rapidly absorbed by the plant surface (leaves/stems) or roots.
- Disruption: It binds to the "tubulin" protein inside the fungal cells. This prevents the formation of microtubules, which are essential for cell division.
- Elimination: Without cell division (mitosis), the fungus cannot grow or reproduce. The infection is halted ("Mitotic Arrest"), and existing fungal threads (hyphae) die off.
Note: Because it moves systemically, it protects parts of the plant that may not have been directly sprayed.

| Fruit Crops (Apple, Grapes) | Scab, Anthracnose, Downy Leaf Spot |
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) |
|---|---|---|---|---|
| Paddy (Rice) | 250 – 500 g | 150 – 200 L | 1.5 – 2.5 g | 30 – 60 |
| Tomato & Chilli | 150 – 300 g | 150 – 200 L | 1 – 1.5 g | 3 – 7 |
| Groundnut | 90 – 200 g | 150 – 200 L | 0.5 – 1.0 g | 14+ |
| Apple / Grapes | N/A (High Vol) | As required | 0.5 – 1.0 g | 7 – 14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: For Wheat Loose Smut, use 2g/kg as Seed Treatment.
How to Apply: Best Practices
- Timing: Apply as a preventive measure or at the very first sign of disease. For Loose Smut, apply only as a seed treatment before sowing.
- Mixing: Bavistin is a Wettable Powder (WP). Pre-mix the required quantity in a small bucket of water to form a smooth paste (slurry) before adding it to the main tank.
- Coverage: Ensure thorough coverage of the foliage. Use a hollow cone nozzle for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray against the wind.
