Privintal Bv (Krishaj): Advanced Antiviral & Fungal Defense for Crops
Stop Chilli Leaf Curl and Phytophthora Rot with the power of Polyformphos technology.
Farming high-value crops like Chilli, Tomato, and Pointed Gourd comes with high risks—especially from viral attacks and fungal rotting. Privintal Bv by Krishi Rasayan (KREPL) is not just a fungicide; it is a specialized "Plant Health" formulation. Designed to combat resistant viral pathologies and fungal complexes, it acts as an immunity booster for your plants.
Privintal Bv uses "soft chemistry" to help your crops recover from viral shock and stops disease spread, ensuring your hard work translates into a high-quality harvest.

How It Works: Mode of Action
Privintal Bv operates differently from standard contact fungicides. It works from the inside out using a proprietary "Polyformphos" technology.
- Systemic Absorption: Being fully water-soluble, it is quickly absorbed by the leaves and roots, spreading throughout the plant's system.
- Immune Trigger (SAR): It mimics a pathogen attack, tricking the plant into activating its own "immune system" (Systemic Acquired Resistance). This produces natural defense proteins to fight viruses.
- Fungistatic Action: Specifically against rot (Oomycetes), it stops the fungus from reproducing (inhibiting sporangia formation), effectively freezing the disease in its tracks.
This dual mechanism allows the plant to produce fresh, healthy leaves even after a viral attack.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli & Capsicum | Leaf Curl Virus (ChiLCV), Mosaic Virus, Fruit Rot |

| Cucurbits (Pointed Gourd/Parwal) | Fruit & Vine Rot (Phytophthora), Downy Mildew |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Since Privintal Bv is a high-value product, precise dosing is essential for cost-effectiveness.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 200 - 250 g | 150 - 200 L | 1.5 - 2 g | 5 - 7 Days |
| Tomato & Veg | 200 g | 150 L | 1.5 g | 5 Days |
| Pointed Gourd | 200 g | 150 L | 1.5 g | 7 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 or at the very first sign of Leaf Curl or Rot. Early application prevents the disease from establishing in the field.
- Mixing: Privintal Bv is compatible with most insecticides. However, avoid mixing with highly alkaline substances (like Bordeaux mixture).
- Coverage: Ensure thorough coverage of the foliage. Since it is systemic, absorption is key. Spray during cooler parts of the day.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Privintal Bv a chemical or organic product?
It is a "soft chemistry" product based on Phosphonates. It bridges the gap between chemicals and biologicals, offering high efficacy with low environmental impact.
2. Does it kill the virus immediately?
No chemical "kills" a virus instantly. Privintal stops the virus from replicating and boosts the plant's immunity, allowing the crop to grow fresh, healthy leaves ("Recovery").
3. Can it cure Fruit Rot in Pointed Gourd (Parwal)?
Yes, it is highly effective against Phytophthora rot. It works best preventively to stop the spores from germinating and spreading to healthy fruits.
4. What is the pack size and price?
The standard pack is 200g, designed for 1 acre. It is a premium product (approx. ₹950-₹1050 per pack) due to its specialized antiviral technology.
5. Can I mix it with growth promoters like Paushak?
Yes, KREPL recommends using it alongside growth promoters for a "Synergistic Effect"—Privintal fights the disease while the promoter boosts growth.
