Acrisio® Fungicide: A Comprehensive Guide

1. Introduction Of Acrisio® Fungicide

In the realm of modern crop protection, the fungicide trade-name Acrisio® stands out as a high-performance tool for managing powdery mildew in high-value crops. Manufactured by BASF Crop Protection, this product brings a novel chemical mode of action that helps growers manage disease and resistance risk in key crops like grapes and apples.

In this blog post we’ll dive into what makes Acrisio® special, how it works, recommended crops & doses, alternate options, benefits, and frequently asked questions. The content is optimized for SEO and actionable for growers and agronomists.

2. What is Acrisio Fungicide  and How Does It Work?

Acrisio® is a systemic fungicide based on the active ingredient Metrafenone (500 g/L SC formulation) that is classified in the FRAC Group “U8” — a novel chemical class not widely used in India prior to its introduction.)

Mode of action

• The chemistry works by disrupting fungal growth right at the tip of the hyphae, preventing the pathogen from further expanding within plant tissue.
  
• Being systemic, it moves within the canopy and provides whole-plant coverage, helping to protect foliage even in hidden zones.
  
• The novel mode helps with resistance management because it belongs to a less exploited group (U8) in the Indian context.
  

3. Key Benefits Of Acrisio® Fungicide

• Comprehensive disease control: Highly effective against powdery mildew across several crops.
  
• New chemistry / unique mode of action: Minimizes cross-resistance with older fungicides.
  
• Excellent tool for resistance management: Since it’s the only product in U8 group in India (as of info available) it supports rotation programmes.
  
• Systemic protection: Protects the entire plant canopy, not just the sprayed surface.
  

4. Recommended Crops, Doses & Application Of Acrisio® Fungicide

Below are some recommended uses of Acrisio® in Indian conditions (note: always follow the official label for your region). 

*Water-volume may vary depending on canopy size, spray system and local recommendations.

Tips for application:

• Use as a preventive spray when conditions favour powdery mildew (warm, humid, with high overhead canopy).
  
• Ensure good spray coverage – walk the canopy and ensure down-leaf surfaces are reached.
  
• Rotate with fungicides from different FRAC groups to avoid resistance build-up.
  
• Avoid using more than two consecutive sprays of the same mode of action product.
  
• Always observe PHI (pre-harvest interval) and maximum number of sprays per season as per label.
  

5. Alternate Products to Consider Of Acrisio® Fungicide

While Acrisio® is very useful especially for powdery mildew, for an effective disease management programme you should consider other fungicides to rotate and broaden your spectrum. Some alternate or complementary options:

• Fungicides from multisite action groups (less resistance risk) for mixing/rotation.
  
• Broad-spectrum products for mixed disease pressure.
  
• Contact plus systemic fungicides if you face both powdery & downy mildew or other fungal diseases.
  

For example, in the Indian apple-orchard market, BASF has introduced other fungicides such as Cabrio® Top, Merivon® and Signum®.

6. Frequently Asked Questions (FAQs)

Q1: Is Acrisio® only for powdery mildew?
A1: Yes — as per label and manufacturer information, its primary target is powdery mildew. For more complex disease pressure (e.g., downy mildew, leaf spot, scab) additional fungicides may be needed. 

Q2: Can Acrisio® be used on all crops?
A2: It is registered for key crops like grapes, apples, mangoes, cucumber, chili etc in the Indian context. Always check the local registration and label. 

Q3: How many sprays per season are allowed?
A3: The label usually limits the number of applications (and the frequency) to manage risk of resistance and ensure safety. Follow local label instructions—only 1-2 sprays of the same mode of action are recommended before rotation.

Q4: What are key safety/handling considerations?
A4: While Acrisio® is designed for crop protection, safe handling is important: use protective equipment, avoid spray drift to non-target plants or water bodies, follow PHI and ensure proper disposal of containers. The product can be harmful to aquatic organisms if misapplied. 

Q5: When should I apply to be most effective?
A5: Ideally at early disease onset (first sign of powdery mildew) or when conditions are known to favour it (dense canopy, high humidity, moderate temperatures). Preventive applications give better results than curative ones.

7. Final Opinion & Recommendations

In summary, Acrisio® is a highly valuable fungicide for powdery mildew management, especially in high-value crops such as grapes and apples where disease pressure and resistance risk are significant. Its novel mode of action, systemic behaviour, and strong coverage make it a top choice for targeted use.

However, it is not a standalone solution for all fungal diseases, and its effectiveness depends on timely application, correct dosage, spray coverage and integration into a broader disease-management strategy. To get the best results:

• Use Acrisio® as part of a rotation programme to avoid resistance build-up.
  
• Pair with good agronomic practices: canopy management (pruning, spacing), adequate nutrition, and optimal spray coverage.
  
• Monitor disease levels and crop condition, and apply when conditions favour disease development.
  
• Adhere strictly to label instructions for dosage, application timing, mixing compatibility, safety, and PHI.
  

For growers in India (for example in West Bengal, like your location in Egra, West Bengal), emphasise good spray coverage given humid coastal conditions, and ensure you have good calibration of spray equipment to use recommended water volumes and avoid under-dosing.

When used correctly, Acrisio® offers excellent support in reducing powdery mildew, improving canopy health and ultimately improving yield and fruit quality.
