What Is Pyraclostrobin 20% SC Fungicide?

Pyraclostrobin 20% SC is a liquid suspension concentrate containing Pyraclostrobin as the only fungicidal active ingredient.

It is mainly used in foliar disease-management programs where preventive protection and early intervention are required.

The product is valued for:

• Broad disease-management potential where registered
• Preventive activity against susceptible fungal pathogens
• Translaminar movement within treated leaves
• Local redistribution on plant surfaces
• Convenient liquid handling
• Compatibility with structured fungicide programs
• Flexible positioning as a single-active product

Pyraclostrobin is not a multi-site fungicide. It acts at one specific biochemical site and therefore requires careful resistance management.

Importers comparing different fungicide product options should distinguish this single-active SC from fixed-ratio combination fungicides.

How Does Pyraclostrobin Work?

FRAC Group 11 QoI Fungicide

Pyraclostrobin belongs to FRAC Group 11, commonly known as the QoI or strobilurin group.

QoI fungicides act at a specific site in the fungal mitochondrial respiratory chain.

This highly targeted activity can provide strong disease control against susceptible pathogens, but it also creates a significant resistance risk when Group 11 products are overused.

Inhibition of Mitochondrial Respiration

Pyraclostrobin binds to the quinol oxidation site of the cytochrome bc1 complex, also referred to as mitochondrial Complex III.

This blocks electron transport and reduces ATP production.

Without sufficient cellular energy, susceptible fungal pathogens cannot maintain normal:

• Spore germination
• Germ-tube development
• Infection establishment
• Mycelial growth
• Sporulation

The strongest program value is generally achieved before infection becomes well established.

Why Preventive Timing Matters

Germinating spores and early infection structures require substantial energy.

Applying Pyraclostrobin before infection or at the earliest stage of disease development allows the fungicide to interfere before the pathogen causes extensive tissue damage.

The product should not be positioned as a guaranteed cure for severe, established disease.

Preventive, Translaminar and Local Activity

Preventive Protection

Pyraclostrobin is primarily positioned as a preventive fungicide.

Suitable application timing may include:

• Before expected infection
• At the beginning of a high-risk weather period
• When disease forecasting indicates increasing pressure
• Before visible symptoms become widespread
• At the first sign of disease where the label permits early intervention

Once plant tissue has been seriously damaged, fungicide application cannot restore it.

Early-Stage Disease Suppression

Some registered programs may include early-stage or limited post-infection activity.

This should not be confused with strong eradicative action.

Correct wording includes:

• Early infection suppression
• Early-stage disease management
• Limited curative activity where supported by the label
• Application before disease becomes established

The product should not be promoted as eliminating advanced infections.

Translaminar Movement

After application, Pyraclostrobin can move from the treated leaf surface into the leaf tissue and toward the opposite side.

This translaminar activity helps improve protection within treated leaves.

However, it does not mean that a small amount of spray can protect the entire plant.

Local Redistribution

Pyraclostrobin can redistribute locally across treated plant surfaces.

This may improve deposit continuity around the application area, but it does not replace proper nozzle selection, spray volume or canopy penetration.

Coverage Still Matters

Spray coverage remains important because Pyraclostrobin should not be treated as a fully systemic product that automatically protects all new growth.

Applications should reach:

• Upper leaf surfaces
• Lower leaf surfaces
• Inner canopy foliage
• Young leaves
• Infection-prone plant tissues
• Dense crop areas

New plant growth emerging after treatment may require protection from a later registered application.

Typical Crop and Disease Directions

Pyraclostrobin has broad commercial use potential, but every crop and disease claim must be supported by the exact destination-market registration.

Crop Direction	Typical Disease Direction	Product Positioning
Cereals	Rusts, leaf spots and other registered foliar diseases	Preventive foliar disease programs
Rice	Sheath, leaf and panicle disease programs where registered	Early disease management
Soybean and Legumes	Rust, anthracnose and leaf spots	Foliar protection where approved
Vegetables	Powdery mildew, Alternaria, anthracnose and other registered diseases	Crop-specific use
Grapes	Powdery mildew and other approved fungal diseases	Preventive canopy protection
Fruit Crops	Anthracnose, leaf spots and other registered diseases	Early infection management
Potatoes and Field Crops	Crop-specific foliar diseases	Registration-dependent
Ornamentals	Registered foliar fungal diseases	Variety and label confirmation required

The table describes common Pyraclostrobin market directions. It is not a universal global label.

Pyraclostrobin in Cereal Disease Programs

Pyraclostrobin may be positioned in registered cereal programs for diseases such as:

• Rust diseases
• Septoria-related leaf diseases
• Net blotch
• Tan spot
• Other registered foliar pathogens

Applications should be timed according to crop growth stage, disease risk and local resistance-management guidance.

Repeated Group 11 use should be avoided.

Pyraclostrobin in Rice Disease Programs

Registered rice uses may include sheath, leaf or panicle disease-management programs.

The exact positioning depends on:

• Rice variety
• Disease species
• Crop stage
• Application method
• Water management
• Local disease pressure
• Registration status

Pyraclostrobin 20% SC should not be promoted for every rice disease unless the local label includes those claims.

Pyraclostrobin in Fruits and Vegetables

Fruit and vegetable programs may use Pyraclostrobin against selected powdery mildew, anthracnose, Alternaria and leaf-spot diseases.

Application planning must consider:

• Crop sensitivity
• Canopy density
• Harvest timing
• Pre-harvest interval
• Spray residue management
• Export-market MRL requirements

Greenhouse uses require separate confirmation. An outdoor registration does not automatically authorize protected-crop use.

Oomycete Disease Claims

Late blight, downy mildew and other Oomycete diseases should only be included where the exact registered label supports them.

The presence of broad-spectrum activity in the active ingredient does not mean every Pyraclostrobin 20% SC product has identical approved claims.

When Should Pyraclostrobin 20% SC Be Applied?

Before Disease Establishment

Preventive application is the preferred position for Pyraclostrobin.

Treatment may be considered when:

• Weather favors infection
• Disease has appeared in the region
• The crop is entering a susceptible stage
• Field history indicates high disease pressure
• Forecasting models indicate infection risk
• The first symptoms are detected and the label permits early treatment

Before Canopy Closure Becomes a Barrier

Dense foliage can reduce spray penetration.

Applications should be planned before the canopy becomes too difficult to cover, or spray equipment and water volume should be adjusted accordingly.

According to the Registered Interval

Spray intervals depend on:

• Crop
• Disease
• Product rate
• Weather
• Disease pressure
• Growth stage
• Resistance-management restrictions

There is no universal application interval for every market.

Avoid Late Rescue Expectations

Pyraclostrobin should not be relied upon as the only treatment when:

• Disease is already severe
• Large areas of tissue are damaged
• The pathogen is resistant to Group 11 fungicides
• Multiple infection cycles have occurred
• Spray coverage is no longer possible

A different fungicide program may be required according to the local label.

Application Guidance

1. Confirm the Crop and Disease

Before application, verify:

• Registered crop
• Disease identification
• Crop growth stage
• Disease-development stage
• Local resistance status
• PHI and REI requirements

Misidentifying a bacterial, viral or physiological disorder as a fungal disease may lead to ineffective treatment.

2. Apply Preventively or Very Early

Do not wait for severe symptoms.

The product performs best when infection is prevented or interrupted at an early stage.

3. Calibrate the Sprayer

Check:

• Nozzle condition
• Spray pressure
• Water volume
• Ground speed
• Boom or nozzle position
• Spray pattern
• Tank agitation

Uneven application can leave unprotected areas.

4. Use Adequate Canopy Coverage

Spray volume should be sufficient to reach the target foliage without excessive runoff.

Dense crops may require:

• Higher approved water volume
• Slower travel speed
• Improved nozzle arrangement
• Better inner-canopy penetration

5. Maintain Agitation

Pyraclostrobin 20% SC contains suspended particles.

Maintain agitation:

• During tank filling
• While adding the product
• During application
• After operational interruptions

6. Follow the Registered Rate

Do not use a universal global rate.

The correct rate depends on the crop, disease, country, application method and approved label.

Reduced rates may provide incomplete disease control and increase resistance-selection pressure.

7. Respect PHI and REI

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

Do not transfer an interval from another Pyraclostrobin formulation or another country.

Pyraclostrobin 20% SC Formulation Features

SC means Suspension Concentrate.

Fine Pyraclostrobin particles are dispersed in a water-based liquid carrier.

The formulation must remain physically stable during storage and redistribute uniformly before and during application.

Advantages of the SC Formulation

A well-developed SC formulation may offer:

• Convenient liquid measurement
• No liquid organic-solvent system typical of many EC products
• Good compatibility with commercial filling lines
• Controlled particle size
• Efficient dilution in spray water
• Reduced dust compared with dry powders
• Flexible bottle and container options

The final hazard profile still depends on the complete formulation.

Key Quality Parameters

Suspension Stability

Some settling may occur during long-term storage.

The formulation should return to a uniform suspension after the approved shaking or agitation procedure.

Hard sediment that cannot be redispersed may lead to uneven application.

Particle Size

Particle size affects:

• Suspension behavior
• Spray uniformity
• Nozzle passage
• Leaf deposition
• Storage stability

Oversized particles may increase sediment or nozzle-blockage risk.

Packaging Compatibility

Bottle, cap, liner, induction seal and label adhesive should be tested with the final SC formulation.

Packaging checks should include:

• Leakage
• Seal integrity
• Cap security
• Bottle deformation
• Label adhesion
• High-temperature storage
• Freeze-thaw exposure where relevant
• Long-distance shipping

Main Product Advantages

Single-Active Product Flexibility

A single-active Pyraclostrobin product allows local agronomists and registration partners to build crop-specific programs around their approved disease spectrum.

It can be positioned:

• As a stand-alone product where permitted
• In rotation with other FRAC groups
• In label-approved tank mixtures
• As part of a distributor’s broader fungicide portfolio

Broad Commercial Crop Direction

Pyraclostrobin has established market relevance in cereals, rice, fruits, vegetables and other commercial crops.

The final product page should preserve this broad commercial positioning while clearly stating that approved uses differ by market.

Preventive Disease-Management Value

Pyraclostrobin is most valuable when applied before severe disease development.

This makes it suitable for planned fungicide programs rather than only reactive spraying.

Convenient SC Supply Format

The 20% SC specification provides a practical liquid format for:

• Importers
• Agricultural distributors
• Registration companies
• Commercial farms
• Crop protection brands

Single-Active Pyraclostrobin vs Combination Fungicides

Buyers comparing Pyraclostrobin fungicide products should distinguish between a single-active SC and a factory-formulated combination.

Comparison Factor	Pyraclostrobin 20% SC	Pyraclostrobin Combination Fungicide
Number of Active Ingredients	One	Two or more
FRAC Profile	Group 11 only	Depends on the partner active ingredient
Program Flexibility	Allows local partner selection	Fixed active ingredient ratio
Resistance Management	Requires rotation or an effective partner	May include another FRAC group
Formulation	SC	SC, WDG or another formulation
Registration Identity	Single-active registration	Separate combination registration
Buyer Positioning	Flexible single-active product channel	Market-ready combination product

A combination product is not automatically superior.

Selection should consider:

• Target disease
• Resistance status
• Registered crops
• Partner activity
• Formulation preference
• Distributor strategy
• Local market demand

Importers requiring Group 11 activity combined with a multi-site protective component can review the Pyraclostrobin + Metiram combination fungicide.

Fungicide Resistance Management

Pyraclostrobin is a single-site FRAC Group 11 fungicide.

Group 11 fungicides have a high resistance risk in several important pathogen groups.

Cross-Resistance within FRAC Group 11

Products containing the following active ingredients may belong to the same resistance group:

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

Rotating only between these active ingredients does not provide a true change in mode of action.

Do Not Depend on Repeated Group 11 Applications

Repeated consecutive use can increase selection pressure.

Avoid:

• Continuous Pyraclostrobin applications
• Rotation only with another Group 11 product
• Repeated reduced rates
• Late curative use
• Multiple Group 11 products in the same program without considering total exposure

Resistance-Management Principles

• Apply preventively.
• Use the complete registered rate.
• Limit the number of Group 11 applications.
• Avoid consecutive Group 11 sprays where the label or FRAC guidance restricts them.
• Rotate with effective fungicides from other FRAC groups.
• Use mixtures only when the partner controls the target disease.
• Follow crop-specific resistance guidance.
• Integrate sanitation and resistant varieties where available.
• Monitor fields after treatment.
• Investigate unexpected disease survival.

Existing QoI Resistance

Where the pathogen population is already resistant to Group 11 fungicides, Pyraclostrobin may provide reduced or no control.

Increasing the rate should not be presented as a solution to confirmed resistance.

Tank Mixing and Compatibility

Pyraclostrobin 20% SC should not be described as compatible with every pesticide, fertilizer or adjuvant.

Compatibility may be influenced by:

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

General Mixing Principles

Where the label permits:

1. Fill the tank partly with clean water.
2. Start agitation.
3. Shake the Pyraclostrobin 20% SC container.
4. Add the measured product.
5. Add approved tank-mix partners in the correct sequence.
6. Complete filling with water.
7. Maintain agitation during application.
8. Use the mixture within the recommended period.

Compatibility Test

Conduct a small jar test before preparing an unfamiliar mixture.

Observe for:

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

Physical compatibility does not guarantee crop safety or biological effectiveness.

Most Restrictive Label

When products are mixed, follow the most restrictive requirement concerning:

• Crop
• Rate
• Application timing
• PHI
• REI
• PPE
• Seasonal use
• Environmental protection

A tank mixture does not replace a formally registered combination product.

Crop Response Beyond Disease Control

Some Pyraclostrobin programs have been associated with physiological crop responses beyond visible disease reduction.

Reported responses may include:

• Extended green-leaf duration
• Changes in crop senescence
• Improved maintenance of photosynthetic tissue
• Better crop condition under certain disease and environmental situations

These effects depend on:

• Crop
• Variety
• Disease pressure
• Application timing
• Weather
• Nutrition
• Local registration claims

Pyraclostrobin 20% SC should not be promoted as guaranteeing higher yield, drought tolerance or improved crop quality.

Its primary function remains fungal disease management.

Crop Safety and Use Precautions

Use only on registered crops and varieties.

Crop response may be influenced by:

• Growth stage
• Temperature
• Water stress
• Variety sensitivity
• Spray overlap
• Tank-mix partners
• Adjuvant selection
• Greenhouse conditions
• Previous pesticide treatments

Greenhouse Use

Do not assume that an outdoor crop registration also permits greenhouse use.

Protected crops can experience different:

• Temperature
• Humidity
• Drying time
• Spray concentration
• Residue behavior
• Variety sensitivity

Greenhouse application requires specific registration support.

Spray Overlap

Overlap may increase crop exposure.

Avoid double application near:

• Field boundaries
• Headlands
• Obstacles
• Turning areas
• Irregular rows

Operator Safety
