How It Works: Mode of Action
Kavach works by attacking the fungus at multiple points, making it nearly impossible for the disease to survive or mutate.
- Energy Blockade: The active ingredient binds to thiol groups inside fungal cells, shutting down their energy production (ATP).
- Spore Shield: It creates a toxic barrier on the leaf surface. When a spore lands and tries to grow, it is neutralized instantly.
- Systemic Kick-Back (Flo Only): The Difenoconazole component in Kavach Flo enters the leaf to kill fungus that has already penetrated the skin.
Result: A completely protected leaf surface where diseases cannot take root.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Coverage is king—ensure the spray reaches the lower leaves.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (per Acre) | Water (L / Acre) | Dose (per Litre) | PHI (Days) |
|---|---|---|---|---|
| Tomato / Potato | 300-400g (WP) 400ml (Flo) |
200 L | 2 g / ml | 14 Days |
| Chilli | 400g (WP) 400ml (Flo) |
200 L | 2 g / ml | 10 Days |
| Groundnut | 350-460g | 200 L | 2 g | 14 Days |
| Grapes | 600-800g | 400 L | 1.5 - 2 g | 60 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Apply prophylactically (preventively) before disease symptoms appear, especially when weather is cloudy or humid.
- Mixing: Do NOT mix with alkaline substances like Bordeaux mixture or Lime Sulfur (pH > 8).
- Coverage: Use 200 Liters of water per acre. Ensure the underside of leaves is sprayed, as this is where pests like Downy Mildew hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
Frequently Asked Questions
1. Which is better, Kavach WP or Kavach Flo?
Kavach WP is excellent for dry weather and cost-effective preventive sprays. Kavach Flo is superior during the rainy season because it is rainfast within 1 hour and has curative properties.
2. Does Kavach cure the disease after it appears?
Kavach WP is primarily preventive (stops new infection). However, Kavach Flo contains Difenoconazole, which offers curative "kick-back" action for established infections.
3. Can I mix Kavach with insecticides?
Yes, it is generally compatible with common insecticides like Thiamethoxam or fungicides like Metalaxyl. Do not mix with oil-based emulsifiable concentrates (EC) or alkaline products.
4. Is Kavach safe for flowering crops?
Yes, Chlorothalonil is generally non-toxic to honeybees, making it a safe choice for crops like chilli and tomato during the flowering stage.
5. Why is the PHI for grapes so long (60 days)?
Grape berries retain residues longer. To meet export standards (MRLs), Kavach should only be used in the early stages of vine growth, not when fruits are maturing.
