Fosetyl-aluminum 30% + Thiophanate-methyl 30% + Azoxystrobin 5% WP

What Is This Triple-Active Fungicide?

This product combines Fosetyl-Aluminum, Thiophanate-Methyl and Azoxystrobin in one wettable powder formulation.

The three components provide different disease-management functions:

• Systemic phosphonate activity
• Inhibition of fungal cell division
• Inhibition of mitochondrial respiration
• Preventive protection
• Early infection suppression
• Broader positioning than a single-active fungicide

The product is not a universal treatment for every fungal disease.

Its final crop and disease claims must match the exact registration and local label.

For wider product selection, buyers can review the POMAIS fungicide product portfolio.

How Do the Three Active Ingredients Work?

Fosetyl-Aluminum Systemic Activity

Fosetyl-Aluminum belongs to FRAC Group P07.

After absorption, it can move within the plant and support protection in treated tissues. It is particularly relevant to approved disease programs involving Oomycete pathogens.

Its activity may include:

• Direct effects on susceptible pathogens
• Support for plant defense responses
• Upward and downward movement where supported by crop and application conditions
• Preventive protection against approved diseases

Fosetyl-Aluminum should not be described as controlling every root, stem or leaf disease.

Thiophanate-Methyl Mitosis Inhibition

Thiophanate-Methyl belongs to FRAC Group 1 and the MBC fungicide group.

It interferes with microtubule formation and fungal mitosis. This prevents susceptible fungal cells from dividing normally.

Thiophanate-Methyl may provide:

• Systemic activity
• Preventive protection
• Early-stage disease suppression
• Activity against selected registered foliar and tissue diseases

Resistance to MBC fungicides is already established in several pathogen groups. It should not be relied upon where Group 1 resistance is confirmed.

Azoxystrobin Respiratory Inhibition

Azoxystrobin belongs to FRAC Group 11.

It inhibits mitochondrial respiration at the Complex III Qo site. This reduces the energy required for spore germination and early fungal growth.

Azoxystrobin is mainly valued for:

• Preventive protection
• Activity against susceptible foliar pathogens
• Early infection suppression
• Broad crop-market relevance
• Translaminar and locally systemic movement

It is a single-site fungicide with a high resistance risk.

Combined Disease-Control Profile

The three active ingredients provide complementary activity:

Fosetyl-Aluminum supports systemic phosphonate and Oomycete positioning → Thiophanate-Methyl inhibits fungal cell division → Azoxystrobin blocks mitochondrial energy production

The premix may provide broader disease-program flexibility than a single-active product.

However, repeated application still creates resistance pressure on FRAC Groups 1 and 11.

Typical Crop and Disease Directions

The following table describes common product-positioning directions. It is not a universal registration label.

Crop Direction	Typical Disease Direction	Product Positioning
Vegetables	Approved leaf spots, rots and Oomycete diseases	Preventive and early-stage treatment
Fruit Crops	Registered anthracnose, leaf and fruit diseases	Crop-specific disease programs
Grapes and Vines	Approved foliar and Oomycete diseases	Preventive canopy protection
Field Crops	Label-listed leaf, stem and root-zone diseases	Program-based application
Ornamentals	Approved foliar and root diseases	Variety and label confirmation required
Protected Crops	Registered greenhouse diseases	Separate protected-crop approval required

Potential disease directions may include:

• Downy mildew
• Phytophthora-related diseases
• Anthracnose
• Powdery mildew
• Leaf spots
• Blights
• Stem and root diseases
• Other label-approved fungal diseases

Exact efficacy depends on the pathogen, crop, timing, resistance status and application method.

When Should the Product Be Applied?

Preventive Application

The preferred timing is before disease becomes established.

Treatment may be considered when:

• Weather favors infection
• Disease has appeared in nearby fields
• The crop is entering a susceptible stage
• Field history indicates recurring disease pressure
• Disease forecasting identifies a high-risk period

Early Disease Development

Where the label permits, the product may also be used at the earliest stage of infection.

Do not wait until:

• Symptoms are widespread
• Large areas of tissue are damaged
• Multiple infection cycles have occurred
• The pathogen population is known to be resistant

Fungicides cannot restore tissue already destroyed by disease.

Spray Interval

Spray intervals depend on:

• Crop
• Disease
• Weather
• Application rate
• Disease pressure
• Crop growth
• Local resistance-management requirements

There is no one interval suitable for every market.

Application Guidance

1. Confirm the Crop and Disease

Before application, verify:

• Registered crop
• Correct disease diagnosis
• Crop growth stage
• Disease-development stage
• Local resistance history
• PHI and REI

A bacterial, viral or physiological disorder will not be controlled by a fungicide.

2. Apply Preventively or Early

The product should be integrated before severe disease develops.

This is especially important for Azoxystrobin because FRAC Group 11 fungicides perform best when used preventively.

3. Prepare the WP Correctly

WP means Wettable Powder.

The product disperses in water to form a suspension. It does not dissolve completely.

Where permitted by the label:

1. Fill the spray tank partly with clean water.
2. Start agitation.
3. Prepare a slurry or premix where required.
4. Add the measured product slowly.
5. Complete filling with water.
6. Maintain agitation during application.

4. Achieve Uniform Coverage

Coverage is important for preventive disease protection.

The spray should reach:

• Upper and lower leaf surfaces
• Inner canopy foliage
• Young leaves
• Disease-prone stems or fruit surfaces
• Dense crop areas

5. Follow the Registered Rate

Do not apply one global rate across all crops and diseases.

The application rate, water volume and maximum number of treatments must come from the exact local label.

6. Respect PHI and REI

Pre-harvest and re-entry intervals are product- and market-specific.

Do not transfer intervals from another formulation or country.

WP Formulation Features

Fosetyl-Aluminum 30% + Thiophanate-Methyl 30% + Azoxystrobin 5% WP is a high-active-content wettable powder.

A stable WP should wet quickly, disperse evenly and remain suspended during application.

Main Quality Parameters

Quality Parameter	Buyer Relevance
Three-Active Assay	Confirms all declared active ingredient contents
Content Uniformity	Maintains the correct active ratio
Wettability	Supports efficient tank mixing
Suspensibility	Maintains uniform spray concentration
Wet Sieve Residue	Helps reduce nozzle blockage
Particle Size	Influences dispersion and coverage
Moisture Content	Affects storage and caking
Persistent Foam	Influences tank filling
Storage Stability	Supports commercial shelf life
Pack-Weight Accuracy	Supports correct field application

Agitation Requirements

The diluted spray suspension may settle if agitation stops.

Maintain agitation:

• During tank filling
• During transport to the field
• Throughout application
• After spray interruptions

Moisture Protection

WP products should be protected from humidity.

Moisture exposure can cause:

• Caking
• Poor flow
• Slower wetting
• Packaging damage
• Reduced handling quality

Moisture-resistant packaging is therefore important.

Resistance Management

This product combines three FRAC classifications:

• Fosetyl-Aluminum: P07
• Thiophanate-Methyl: Group 1
• Azoxystrobin: Group 11

The premix offers three activity profiles, but it should not be described as resistance-proof.

FRAC Group 1 Risk

Thiophanate-Methyl belongs to the MBC group.

Pathogens resistant to other MBC fungicides may also be resistant to Thiophanate-Methyl.

Changing between Thiophanate-Methyl and another Group 1 fungicide is not an effective mode-of-action rotation.

FRAC Group 11 Risk

Azoxystrobin belongs to the QoI group.

Cross-resistance may occur between Group 11 fungicides such as:

• Azoxystrobin
• Pyraclostrobin
• Trifloxystrobin
• Kresoxim-Methyl
• Other QoI fungicides

Rotating only between Group 11 active ingredients does not provide a meaningful change in mode of action.

Recommended Program Principles

• Apply preventively.
• Use the complete registered rate.
• Avoid repeated consecutive applications.
• Rotate with effective fungicides outside Groups 1 and 11.
• Follow crop-specific FRAC guidance.
• Integrate sanitation and resistant varieties where available.
• Monitor disease response after treatment.
• Investigate unexpected survival or disease development.

The premix should not be applied repeatedly throughout the season without considering total Group 1 and Group 11 exposure.

Tank Mixing and Compatibility

Do not assume compatibility with every pesticide, fertilizer or adjuvant.

Tank-mix performance may depend on:

• Water hardness
• Water pH
• Partner formulation
• Mixing order
• Fertilizer salts
• Tank temperature
• Number of products in the mixture

Conduct a small jar test before preparing an unfamiliar mixture.

Observe for:

• Sediment
• Separation
• Gel formation
• Heat
• Excessive foam
• Irregular suspension

Physical compatibility does not guarantee crop safety or biological performance.

Follow the most restrictive label in the tank mixture.

Crop Safety and Use Precautions

Use only on registered crops and varieties.

Crop response may be influenced by:

• Excessive rate
• Spray overlap
• High temperature
• Water stress
• Sensitive varieties
• Unapproved tank mixtures
• Incorrect application timing
• Greenhouse conditions

Protected-crop use requires specific approval.

An outdoor registration should not be assumed to cover greenhouse production.
