Merivon® Fungicide – Advanced Protection for Healthier and More Productive Crops

Introduction of Merivon® Fungicide

In modern agriculture, plant diseases can cause significant yield losses and compromise quality. Farmers need reliable protection that not only controls fungal infections but also promotes plant vitality. Merivon® Fungicide, developed by BASF, offers an innovative solution with advanced chemistry that ensures long-lasting disease control and improved crop performance. 

Let’s explore how Merivon stands apart as a premium fungicide choice for Indian farmers.

What is Merivon® Fungicide?

Merivon® is a broad-spectrum systemic fungicide from BASF that provides dual-action protection against a wide range of fungal diseases. It contains two highly effective active ingredients:

• Fluxapyroxad (Xemium®) – a SDHI (Succinate Dehydrogenase Inhibitor) fungicide that inhibits fungal respiration, stopping disease development at an early stage.
  
• Pyraclostrobin (F500®) – a strobilurin fungicide that prevents spore germination and restricts fungal growth, while also enhancing plant health.
  

Together, these two molecules deliver outstanding disease control, prolonged protection, and visible improvements in crop vigor and productivity.

Mode of Action – Dual Strength, Complete Protection

Merivon® works through dual systemic action—both translaminar and xylem-mobile movement—ensuring uniform distribution within plant tissues.

• Fluxapyroxad targets fungal mitochondria by blocking the enzyme complex II, leading to energy deprivation and death of fungal cells.
  
• Pyraclostrobin interferes with respiration at the Qo site of complex III, inhibiting spore germination and mycelial growth.
  

This two-way action ensures the fungus is attacked at multiple stages, providing curative, preventive, and residual control. It not only kills existing infection but also protects new growth for extended periods.

Key Benefits of Merivon® Fungicide

1. Broad-Spectrum Control:
   Effectively manages a wide range of fungal diseases such as early blight, powdery mildew, leaf spot, fruit rot, and rust.
   
2. Long-Lasting Protection:
   Offers extended residual activity, reducing the frequency of sprays and saving time and labor costs.
   
3. Enhanced Plant Health:
   Thanks to BASF’s AgCelence® effect, Merivon® improves photosynthesis, water use efficiency, and stress tolerance, resulting in greener, healthier, and more vigorous crops.
   
4. Improved Yield and Quality:
   Ensures higher marketable yields with better fruit size, color, and uniformity.
   
5. Excellent Rainfastness:
   Remains effective even after rainfall due to strong adherence to plant surfaces.
   
6. Resistance Management Tool:
   Dual modes of action help delay resistance buildup in fungal populations, ensuring sustainable use over time.

Recommended Dose and Application of Merivon® Fungicide

• Dosage: 0.5 – 1.0 ml per liter of water (or as per local recommendations)
  
• Spray Volume: 200 – 500 liters per hectare, depending on crop canopy
  
• Application Stage: Apply preventively at the appearance of initial disease symptoms or as a part of a regular spray schedule
  
• Re-application Interval: 10 – 14 days (depending on disease pressure)
  
• Method: Use a knapsack or power sprayer to ensure uniform coverage on all plant surfaces
  

Pro Tip: Alternate Merivon® with fungicides of different chemistry to prevent resistance and maintain long-term effectiveness.

AgCelence® Effect – Beyond Disease Control

One of the most unique features of Merivon® is BASF’s AgCelence® technology, which provides physiological benefits beyond disease protection:

• Enhances chlorophyll content, leading to greener leaves and better photosynthesis.
  
• Improves nutrient uptake and water utilization under stress conditions.
  
• Reduces ethylene production, delaying premature aging and fruit drop.
  
• Promotes stronger stems, improved flowering, and better fruit set.
  

Farmers who use Merivon® often report visibly healthier crops with superior growth and better post-harvest quality.

Compatibility and Precautions

• Merivon® is compatible with most commonly used insecticides and fungicides. However, it’s best to conduct a jar test before mixing.
  
• Avoid spraying during high wind or intense sunlight.
  
• Always wear protective clothing and follow label instructions.
  
• Store in a cool, dry place away from direct sunlight and food items.
  

Alternate Products

If Merivon® is unavailable or you wish to rotate products for resistance management, the following fungicides can be used alternately:

• Cabrio® Top (BASF) – For broad-spectrum protection and plant health benefits.
  
• Acrobat® Complete (BASF) – Ideal for controlling downy mildew and late blight.
  
• Score® (Syngenta) – Effective triazole-based fungicide for many foliar diseases.
  
• Amistar Top (Syngenta) – Combines strobilurin and triazole chemistry for preventive and curative control.
  

Frequently Asked Questions (FAQs)

1. What makes Merivon® different from other fungicides?
Merivon® combines two advanced molecules—Fluxapyroxad and Pyraclostrobin—that deliver superior disease control and crop vitality benefits.

2. Can Merivon® be used during fruiting?
Yes, it is safe for use during flowering and fruiting stages, but always adhere to the pre-harvest interval (PHI) as mentioned on the label.

3. How often should Merivon® be applied?
Generally, every 10–14 days based on disease intensity and weather conditions.

4. Does Merivon® improve yield quality?
Yes. Beyond disease protection, it enhances leaf health, fruit size, and overall yield quality.
