Krisulf 80% WDG | Premium Sulphur Fungicide, Miticide & Nutrient
The Ultimate "Triple Action" Protection for Grapes, Mangoes, and Field Crops.
Krisulf 80% WDG by Krishi Rasayan is a high-tech evolution of traditional sulphur. Unlike messy dusts, these Water Dispersible Granules (WDG) dissolve instantly to provide powerful protection against Powdery Mildew and Mites while nourishing your crops with essential Sulphur.
Best For: Managing fungicide resistance, boosting oil content in seeds, and ensuring spot-free fruits for export.
Why Choose This Product? Key Benefits
-
🛡️
Triple Action Power: Acts as a Fungicide, a Miticide (kills mites), and a plant Micronutrient all in one spray.
-
⏱️
Instant "Bloom" Dispersion: Advanced WDG technology ensures granules disperse immediately in water, preventing nozzle clogging and ensuring uniform coverage.
-
🌿
Nutrient Boost: Corrects sulphur deficiency, improves protein synthesis, and significantly increases oil content in oilseed crops.
-
🌧️
Excellent Rainfastness: Micronized particles (1-8 microns) stick firmly to the leaf surface, providing long-lasting protection even in challenging weather.
-
⏳
Resistance Management: With a multi-site mode of action, it is the perfect tank-mix partner to prevent pests from becoming immune to other chemicals.

How It Works: Mode of Action
Krisulf works through "Contact and Vapor Action." Once applied, the micronized sulphur particles release vapors that penetrate fungal spores and mites.
- Multi-Site Attack: It disrupts the fungus's respiration and energy production (ATP) at multiple levels, making it nearly impossible for resistance to develop.
- Toxic Gas Formation: Inside the fungal cell, sulphur is converted into Hydrogen Sulfide ($H_2S$), which is toxic to the pathogen.
- Mite Control: It physically irritates mites and disrupts their metabolic processes, suppressing populations of Red Spider Mites and Rust Mites.
Note: The vapor action allows the fungicide to reach hidden crevices and the undersides of leaves where pests hide.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure thorough coverage of the foliage.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 750 – 1000 g | 300 – 400 L | 2.5 – 3.0 g | 7 – 15 |
| Mango | 750 – 1000 g | Highly variable | 2.5 – 5.0 g | 7 – 10 |
| Wheat & Cumin | 1000 g | 200 – 300 L | 3.0 – 5.0 g | 14 |
*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: Start spraying as a preventive measure when weather favors disease (humid/cloudy) or at the very first sign of disease.
- Compatibility Warning: NEVER mix with Oil. Keep a gap of at least 14 to 30 days between a Sulphur spray and any Oil spray (Neem oil or Emulsifiable Concentrates) to avoid burning leaves.
- Temperature Check: Avoid spraying when temperatures exceed 30°C (86°F) to prevent "sulphur burn" or scorching of the crop.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use leather gloves.
Frequently Asked Questions
1. Is Krisulf 80% WDG better than Sulphur Dust?
Yes. WDG technology creates a suspension in water, offering far better leaf coverage, less wastage, and significantly lower inhalation risks for the farmer compared to dusting powders.
2. Can I use this on all crops?
It is safe for most crops, but avoid "sulphur-shy" plants like Cucurbits (cucumber, melon) and Apricots, especially in hot weather, as it may cause leaf burn.
3. Does it kill mites?
Yes, Krisulf is an effective acaricide. It suppresses Red Spider Mite and Rust Mite populations, often reducing the need for separate chemical miticides.
4. What is the benefit for Groundnut and Mustard?
Sulphur is a key nutrient for oil synthesis. Using Krisulf on these crops not only controls disease but helps increase the oil percentage and protein content in the harvest.
5. Is it suitable for export crops?
Yes. Sulphur is generally exempt from MRLs (Maximum Residue Limits) in many countries (like the EU). However, ensure you stop spraying 7-15 days before harvest to avoid visible spots on fruit.
Safety & Disclaimer
Always read and follow the instructions on the official product label. The information provided here is for guidance only. Use personal protective equipment (PPE) during application. Do not contaminate water bodies as sulphur is toxic to fish.
