What Is Beauveria bassiana 15 Billion Spores/g WP?

Beauveria bassiana is a naturally occurring entomopathogenic fungus capable of infecting susceptible insects.

The active component of this product consists of fungal spores rather than a conventional chemical insecticide molecule.

It is mainly positioned for:

• Biological insect control
• Integrated pest management
• Early pest-population suppression
• Greenhouse and open-field programs
• Foliar insect management
• Soil and root-zone pest treatment where registered
• Programs seeking to diversify insect-control methods

Beauveria bassiana is a fungus, but this product is not a crop-disease fungicide.

Its commercial purpose is to infect and control insect pests.

Buyers developing broader crop protection programs can review the POMAIS insecticide product portfolio.

What Does 15 Billion Spores per Gram Mean?

The specification indicates a declared concentration of:

1.5 × 10¹⁰ spores in each gram of formulated product

This number is an important product identity, but it does not provide a complete assessment of microbial quality.

Total Spore Count

Total spore count measures the number of spores detected in a defined product quantity.

It may include both viable and non-viable spores, depending on the test method.

Viable Spore Count

Viable spores are capable of germinating and contributing to biological infection.

A B2B product specification should ideally state:

• Minimum viable spores per gram
• Test method
• Release specification
• Expiry specification
• Acceptable batch variation

Some laboratories may express biological activity as viable conidia/g or CFU/g. These terms should not be treated as identical without reviewing the analytical method.

Germination Rate

The germination rate shows the percentage of tested spores that germinate under defined laboratory conditions.

It can be affected by:

• Strain
• Production process
• Drying conditions
• Moisture
• Storage temperature
• Product age
• Packaging quality

For microbial pesticides, viable spore count and germination rate are often more useful for procurement decisions than total spore count alone.

Strain Identity

The product should also identify the Beauveria bassiana strain used in production.

Different strains may differ in:

• Pest virulence
• Host range
• Environmental adaptation
• Speed of infection
• UV tolerance
• Storage stability
• Crop registration
• Non-target profile

Efficacy claims from another Beauveria bassiana strain should not be transferred automatically to this product.

How Does Beauveria bassiana Infect Insect Pests?

Spore Attachment

The infection process begins when viable fungal spores contact the external surface of a susceptible insect.

Spores may attach to:

• Cuticle
• Leg joints
• Mouthpart areas
• Membrane sections
• Other exposed body surfaces

Because the product works through contact infection, uniform application and direct exposure are important.

Spore Germination

Under suitable environmental conditions, attached spores absorb moisture and begin to germinate.

A germ tube develops from the spore and grows across the insect surface.

If conditions are too dry, too hot or otherwise unfavorable, germination may be delayed or reduced.

Cuticle Penetration

The fungus penetrates the insect cuticle through a combination of mechanical pressure and biological activity.

The process may involve enzymes associated with the breakdown of:

• Proteins
• Chitin
• Lipids
• Other cuticle components

This distinguishes Beauveria bassiana from insecticides that require ingestion or act directly on a specific nerve receptor.

Internal Colonization

After entering the insect body, the fungus develops within internal tissues and body fluids.

This disrupts normal functions such as:

• Feeding
• Movement
• Metabolism
• Water balance
• Tissue integrity
• Immune response

The infected pest gradually becomes less active and eventually dies.

External Sporulation

Under suitable humidity, white fungal growth may appear on the surface of a dead insect.

This characteristic appearance is sometimes described as white muscardine disease.

Visible sporulation is not required to confirm every successful infection. Environmental conditions may prevent external fungal growth even when mortality has occurred.

How Quickly Does Beauveria bassiana Work?

Beauveria bassiana is not an immediate knockdown insecticide.

The product requires time for:

1. Spore attachment
2. Germination
3. Cuticle penetration
4. Internal fungal development
5. Pest mortality

Visible suppression may therefore take several days.

Performance depends on:

• Strain virulence
• Viable spore concentration
• Pest species
• Pest life stage
• Application coverage
• Temperature
• Humidity
• UV exposure
• Pest density
• Repeat treatment program

The product is generally more suitable for early pest management than emergency rescue of a severe outbreak.

Target Pest Directions

The following table describes common Beauveria bassiana market directions. Exact claims depend on the strain, registration and supporting efficacy data.

Pest Group	Typical Direction	Product Positioning
Whiteflies	Registered greenhouse and field whitefly species	Foliar contact infection
Thrips	Exposed crop-specific thrips	Early population suppression
Aphids	Registered aphid species	Direct foliar contact
Leafhoppers and Planthoppers	Approved nymphs and adults	Crop-specific use
Mealybugs and Scale Crawlers	Exposed immature stages	Registration-dependent
Caterpillars	Young armyworms, borers and other approved larvae	Early larval treatment
Beetles and Weevils	Exposed adults or larvae	Foliar or soil direction
White Grubs	Approved root-feeding beetle larvae	Soil or root-zone application
Grasshoppers	Registered grasshopper species	Field application
Mites	Selected registered mite species	Strain- and label-specific

The product should not be promoted as controlling every insect species known to be susceptible to Beauveria bassiana at the species level.

Whitefly, Thrips and Aphid Programs

Small sucking pests are important biological-control directions for Beauveria bassiana products.

Effective application should reach the areas where pests remain, including:

• Leaf undersides
• Young leaves
• Inner canopy foliage
• Growing points
• Colonies around stems or petioles

Adults, nymphs and other exposed stages may differ in susceptibility.

Monitoring should continue after application because newly emerged pests may not have been exposed to the original spray deposit.

Caterpillar and Beetle Programs

Beauveria bassiana may be positioned against selected caterpillars, beetles and weevils where the strain and label support these claims.

Young and exposed stages are generally more practical targets than large, concealed or heavily protected insects.

Control may be reduced when pests are:

• Inside stems
• Deep within fruit
• Protected under dense webbing
• Below inaccessible soil layers
• Already at a severe population level

Application timing should be based on pest monitoring and life-stage development.

Soil and White Grub Programs

Some Beauveria bassiana WP products are used in soil or root-zone programs against white grubs and other susceptible soil insects.

Potential application directions include:

• Root-zone drench
• Soil incorporation
• Treatment with carrier material
• Nursery-bed application
• Other registered soil methods

Soil performance may depend on:

• Moisture
• Temperature
• Organic matter
• Soil structure
• Spore distribution
• Pest depth
• Chemical residues
• Microbial competition

The product should not be promoted for all soil pests without strain-specific efficacy data.

Typical Crop and Application Systems

Greenhouse and Protected Crops

Potential crop directions include:

• Tomatoes
• Peppers
• Cucumbers
• Eggplants
• Ornamentals
• Nursery plants

Common pest directions may include whiteflies, thrips, aphids, mealybugs and selected mites.

Protected environments may provide more manageable temperature, humidity and coverage conditions, but greenhouse use still requires specific registration.

Field Vegetables

Potential directions include:

• Brassicas
• Cucurbits
• Legumes
• Leafy vegetables
• Solanaceous crops
• Allium crops

Target pests may include aphids, whiteflies, thrips, beetles and young caterpillars.

Field Crops

Potential crop directions may include:

• Maize
• Cotton
• Rice
• Soybean
• Peanuts
• Other registered crops

The approved pest spectrum depends on the strain and local label.

Orchard and Fruit Crops

Potential directions include:

• Citrus
• Grapes
• Berries
• Tropical fruits
• Other approved orchard crops

Common market directions may include thrips, whiteflies, mealybugs, scale crawlers, beetles and weevils.

Nursery and Soil Systems

Beauveria bassiana WP may also be considered for:

• Seedling media
• Nursery beds
• Root zones
• Ornamental production
• Forestry systems
• Soil pest programs

Each application system requires separate rate and handling instructions.

When Should the Product Be Applied?

At the Beginning of Infestation

The preferred timing is when target pests first appear and populations remain manageable.

Early application improves the probability that:

• Exposed pests contact viable spores
• Younger pest stages are treated
• Coverage reaches active colonies
• Repeat applications can be planned
• Population growth is interrupted before severe damage

Before Severe Outbreaks

Do not rely on Beauveria bassiana as the only emergency treatment when:

• Pest density is already very high
• Crop damage is advanced
• Multiple pest stages are hidden
• The canopy prevents adequate coverage
• Environmental conditions are unfavorable
• Immediate chemical knockdown is required

A compatible integrated program may be needed.

Based on Pest Monitoring

Treatment decisions should consider:

• Pest species
• Pest density
• Pest life stage
• Crop damage
• Beneficial insects
• Weather
• Previous treatments
• Local economic thresholds

Calendar-based application alone may lead to unnecessary or poorly timed treatments.

Foliar and Soil Application

Foliar Spray

For foliar pests, direct coverage is essential.

The spray should reach:

• Upper and lower leaf surfaces
• Inner canopy foliage
• Pest colonies
• Young shoots
• Feeding sites
• Other protected habitats

Beauveria bassiana does not move systemically through the plant to reach untreated insects.

Soil or Root-Zone Treatment

For registered soil pests, distribute the product evenly within the treatment zone.

Application should consider:

• Pest location
• Root-zone depth
• Soil moisture
• Irrigation timing
• Carrier material
• Soil temperature
• Organic matter

Avoid excessive runoff or uneven concentration.

Application Guidance

1. Confirm the Strain, Crop and Pest

Verify that the product strain and local label support the intended crop, pest and application method.

Do not transfer claims from another Beauveria bassiana product.

2. Apply Early

Begin treatment before pest populations become severe.

Younger, exposed and actively moving stages are often easier to contact.

3. Prepare the WP Suspension

WP means Wettable Powder.

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

Where permitted:

1. Fill the tank partly with clean water.
2. Start gentle agitation.
3. Prepare a premix if required.
4. Add the measured product gradually.
5. Complete filling with water.
6. Maintain agitation during application.

4. Avoid Excessive Mechanical Stress

Use equipment and agitation settings suitable for a microbial formulation.

Follow the product-specific instructions for pumps, filters and nozzles.

5. Achieve Direct Coverage

Target the pest and its habitat rather than only the upper crop canopy.

Coverage is especially important because infection begins when viable spores contact the insect.

6. Use the Mixture Promptly

Do not keep the diluted suspension for extended periods unless the label specifically permits it.

Water contact, heat and contamination may reduce spore viability.

7. Follow the Registered Rate

Do not use one universal application rate.

The required product quantity depends on:

• Strain
• Pest
• Crop
• Infestation level
• Application method
• Spore viability
• Local registration

8. Repeat Only as Directed

Biological programs may require repeat applications because new pests can emerge after the first treatment.

Use the registered repeat interval rather than an assumed calendar schedule.

Environmental Conditions Affecting Performance

Humidity and Moisture

Spore germination requires suitable moisture conditions.

Low humidity or rapidly drying spray deposits may reduce infection success.

Temperature

Temperature affects:

• Spore germination
• Fungal growth
• Pest activity
• Infection speed
• Product stability

The optimal range depends on the strain and formulation.

Sunlight and UV Exposure

Strong ultraviolet exposure can reduce fungal spore viability on exposed surfaces.

Application timing and canopy placement should follow product-specific guidance.

Rainfall and Irrigation

Heavy rain shortly after treatment may remove spores from plant surfaces.

Irrigation may improve or reduce performance depending on the application system, timing and target pest.

Pest Life Stage

Different pest stages may differ in:

• Cuticle structure
• Exposure
• Mobility
• Habitat
• Susceptibility

The most responsive stage should be identified from strain-specific efficacy data.

WP Formulation and Microbial Quality Control

A microbial WP requires both physical formulation testing and biological activity testing.

Key Quality Parameters

Quality Parameter	Buyer Relevance
Strain Identity	Confirms the registered microbial active ingredient
Total Spore Count	Confirms the declared 15 billion spores/g
Viable Spore Count	Measures biologically active spores
Germination Rate	Indicates the ability of spores to begin infection
Virulence Bioassay	Confirms activity against a reference pest
Microbial Contaminants	Controls unwanted bacteria and fungi
Moisture Content	Influences spore survival during storage
Wettability	Supports rapid tank preparation
Suspensibility	Maintains uniform spore concentration
Wet Sieve Residue	Helps reduce nozzle blockage
Particle Size	Influences mixing and equipment performance
pH	Supports formulation-quality assessment
Persistent Foam	Influences filling and spraying
Pack-Weight Accuracy	Supports correct product dosing
Storage Stability	Confirms biological activity during shelf life
Packaging Moisture Barrier	Protects spores from humidity

Batch Release Testing

A microbial batch should not be released based only on product weight or total spore count.

Relevant release checks may include:

• Microbial identity
• Viable spore count
• Germination rate
• Moisture
• Contamination limits
• Biological activity
• Physical WP performance

End-of-Shelf-Life Specification

The expiry specification should confirm that sufficient biological activity remains at the end of the declared storage period.

This is particularly important in hot and humid destination markets.

Tank Mixing and Compatibility

Do not assume that Beauveria bassiana is compatible with every pesticide, fertilizer or disinfectant.

Fungicide Compatibility

Some fungicides may reduce:

• Spore viability
• Germination
• Mycelial growth
• Sporulation
• Field infectivity

Review product-specific compatibility data before mixing Beauveria bassiana with a fungicide.

Other Chemical Products

Compatibility may also be affected by:

• Strongly alkaline products
• Disinfectants
• Oxidizing materials
• Concentrated fertilizers
• Certain surfactants
• Water-treatment chemicals

Compatibility Testing

A physical jar test alone is not sufficient for a microbial pesticide.

A mixture may remain physically uniform while still reducing spore germination or biological activity.

Compatibility assessment may therefore require both:

• Physical testing
• Biological viability testing

Use only label-approved combinations.

IPM and Resistance Management

Beauveria bassiana has a complex biological infection process rather than a conventional single biochemical target.

This makes it useful in diversified integrated pest management programs.

Potential IPM roles include:

• Early biological intervention
• Rotation away from repeatedly used chemical groups
• Programs involving beneficial insects
• Greenhouse pest management
• Resistance-management support
• Reduced dependence on one chemical mode of action

However, the product should not be described as resistance-proof.

Effective IPM still requires:

• Pest monitoring
• Correct identification
• Treatment thresholds
• Crop sanitation
• Removal of heavily infested material
• Compatible biological control
• Responsible chemical use
• Evaluation of surviving populations

Safety and Non-Target Precautions

A biological product should not be described as harmless to every person or non-target organism.

Operator Protection

Handle the product according to the approved label and final SDS.

General precautions may include:

• Avoid inhaling WP dust.
• Wear the required protective clothing.
• Use gloves where specified.
• Protect the eyes during mixing.
• Use respiratory protection where required.
• Avoid skin contact.
• Wash after handling.
• Keep unprotected persons away from the mixing area.

Repeated exposure to microbial proteins may cause sensitization in susceptible individuals.

Pollinator Protection

Do not assume that every Beauveria bassiana strain is harmless to bees or commercial pollinators.

Follow strain-specific restrictions concerning:

• Flowering crops
• Foraging bees
• Managed pollinator colonies
• Application timing
• Direct spray exposure

Aquatic Protection

Prevent the product, spray suspension and equipment rinsate from entering:

• Rivers
• Streams
• Lakes
• Wells
• Fish ponds
• Irrigation canals
• Wetlands
• Drainage systems

Storage and Shelf Life

The active component is a living microorganism.

Storage conditions directly affect product quality.

Store the product:

• In its original sealed package
• Under the product-specific temperature requirement
• In a dry location
• Away from direct sunlight
• Away from excessive heat
• Away from moisture
• Away from food and animal feed
• Under the conditions stated in the label and SDS

Opened Packages

After opening:

• Reseal the package immediately.
• Prevent moisture entry.
• Avoid contamination.
• Follow the permitted use period.
• Do not combine old product with a new batch.

Shelf Life

The shelf life must be supported by strain- and formulation-specific stability data.

Do not assume that all Beauveria bassiana WP products remain active for the same period or under the same temperature conditions.

Beauveria bassiana and Other Microbial Insecticides

Microbial Product Direction	Main Positioning
Beauveria bassiana WP	Contact fungal infection of approved foliar and soil pests
Metarhizium anisopliae Products	Entomopathogenic fungal products with separate strains and pest directions
Bacillus thuringiensis Products	Ingestion-based bacterial control of susceptible larvae
Purpureocillium lilacinum Products	Primarily biological nematode-management direction
Chemical Insecticides	Faster target-specific action depending on the mode of action

The best product depends on:

• Target pest
• Pest life stage
• Crop
• Environmental conditions
• Required speed
• Application system
• Local registration

Microbial products should not be treated as interchangeable solely because they are biological pesticides.
