Sunsulf (Sulphur 80% WDG) – Nichino India
Premium Contact Fungicide, Acaricide (Miticide) & Essential Crop Nutrient
Sunsulf by Nichino India is a high-quality Sulphur 80% WDG (Water Dispersible Granule) formulation designed for modern agriculture. Unlike older dust formulations, Sunsulf features advanced micronized particles (2 to 6 microns) that disperse instantly in water ("bloom effect") to provide superior coverage.
It offers a triple-action solution: it protects crops from fungal diseases like Powdery Mildew, controls harmful Mites, and acts as a potent fertilizer by supplying Sulfur—the "fourth major nutrient"—to boost chlorophyll and plant immunity.
Best For: Grapes, Apples, Cumin, Mango, and Vegetables requiring sulfur nutrition and mildew protection.
Why Choose This Product? Key Benefits
-
⏱️
Instant Dispersion (The "Bloom"): High-quality WDG granules dissolve in water within seconds, ensuring a smooth suspension that never clogs spray nozzles.
-
🛡️
Multi-Site Action: Acts as a Fungicide, Miticide, and Nutrient simultaneously. Its multi-site mode of action (FRAC M2) prevents pests from developing resistance.
-
⏳
Superior Coverage & Retention: Ultra-fine particles (2-6 microns) create a "sulfur vapor cloud" that reaches hidden pests under leaves and inside flower clusters.
-
🌧️
Excellent Rainfastness: The micronized particles adhere strongly to the leaf surface, resisting wash-off from light rains or wind better than powder forms.
-
🌿
Boosts Greenery (Phytotonic Effect): Supplies essential Sulfur required for protein and chlorophyll synthesis, resulting in lush green crops and higher yields.

How It Works: Mode of Action
Sunsulf works through Contact and Vapor Action. The sulfur particles penetrate fungal spores and mite pests, disrupting their life cycle through three main steps:
[Image of powdery mildew life cycle]- Lipid Permeation: Sulfur is lipophilic, meaning it easily crosses the cell membrane of fungi and mites.
- Energy Disruption: Once inside, it interferes with the electron transport chain in the mitochondria, stopping the production of ATP (energy).
- Toxic Accumulation: The fungus attempts to reduce the sulfur, converting it into Hydrogen Sulfide ($H_2S$), which is toxic to the cell proteins, causing rapid death of the pest.
Note: The "Vapor Action" allows it to reach pests hiding in curled leaves or tight grape clusters where direct spray droplets might miss.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Grapes | Powdery Mildew, Mites |
| Apple | Scab, Powdery Mildew |
| Cumin (Jeera) | Powdery Mildew |
| Mango | Powdery Mildew |
| Pea / Cowpea / Guar | Powdery Mildew, Mites |
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 (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes / Apple | 750 – 1000 g | 300 – 400 L | 2.5 g/L | 0 - 3 |
| Cumin / Mango | 750 – 1000 g | 300 – 400 L | 2.5 g/L | 0 - 3 |
| Vegetables (Peas/Beans) | 750 – 1000 g | 300 – 400 L | 2.5 g/L | 0 - 3 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. (Sulfur residues are generally low concern).
How to Apply: Best Practices
- Timing: Use preventively (before severe disease appears) or at the first sign of pests. Avoid spraying during peak heat (>30°C) to prevent leaf burn.
- Mixing: Fill the tank halfway with water. Add the granules slowly; they will disperse instantly. Top up with water.
- Coverage: Ensure thorough coverage of both upper and lower leaf surfaces. The vapor action will help reach hidden crevices.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. IMPORTANT: Do not mix with Neem Oil or other Oils. Keep a 14-21 day gap between Sulfur and Oil sprays.
Frequently Asked Questions
1. Can I mix Sunsulf with Neem Oil or Emulsifiable Concentrates (EC)?
No. Mixing Sulfur with oil or applying it within 2 weeks of an oil spray causes severe phytotoxicity (leaf burn). Always keep a 14-21 day gap.
2. Does Sunsulf help in plant growth?
Yes. It contains 80% Sulfur, which helps in protein formation and chlorophyll synthesis, often leading to a visible "greening" effect on the crop.
3. Is Sunsulf safe for bees?
It is relatively safe for bees compared to synthetic pesticides. However, it is best to spray early in the morning or late evening when bees are not actively foraging.
4. What is the advantage of WDG over Dust formulations?
WDG is dust-free (safer for the user), mixes instantly in water, and provides far better coverage and sticking power than crude dusts, meaning you use less product for better results.
5. Can I use it on vegetables like Tomato or Okra?
Yes, it is effective against mites and mildew on vegetables. Ensure you do not spray when temperatures are very high to avoid scorching.
