Beauveria Biopesticide: Based on the entomopathogenic fungus Beauveria bassiana

A Sustainable, Profitable Solution for Diamondback Moth and Beyond!

The technology is a biopesticide based on the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin, specifically the isolate Bb11 (Bba5653) from the IITA-Benin collection, found in Penessoulou, Benin. Originally designed to control the caterpillars of the cabbage moth (Plutella xylostella), also known as the diamondback moth, this natural fungus produces live spores called conidia. When applied to crops, these spores attach to the insect's cuticle (its outer layer), germinate, and penetrate the insect's internal tissues. The fungus then grows within the insect, causing rapid tissue damage and mortality. Safe for humans, animals, and beneficial insects, this biopesticide offers an eco-friendly, sustainable alternative to chemical pesticides. It is widely used as part of Integrated Pest Management (IPM) strategies for protecting crops from pest damage in both open-field and protected agriculture settings.

Problem

Severe Pest Damage and Yield Losses: Diamondback moth is a major cabbage pest in West Africa and can cause considerable crop losses, reaching up to 90% yield loss and threatening cabbage production.
Pesticide Resistance: Frequent application of synthetic insecticides has contributed to the development of diamondback moth populations resistant to several types of chemical insecticides, making conventional pest management increasingly challenging.
Human and Environmental Risks from Synthetic Pesticides: Frequent reliance on synthetic insecticides creates adverse impacts on human health and the environment, raising concerns for sustainable crop protection.

Solution

Biological Pest Control: Beauveria Biopesticide uses Beauveria bassiana Bb11 to control diamondback moth through fungal conidia that infect the insect and cause mortality, providing an alternative approach to protecting cabbage production.
Alternative for Pesticide-Resistant Pests: Biological control provides an additional crop-protection option where diamondback moth populations have developed resistance to several types of chemical insecticides.
Reduced Reliance on Synthetic Pesticides: The biopesticide offers a natural alternative to frequent synthetic insecticide applications, supporting crop protection with lower reliance on chemical pesticides and their associated human and environmental impacts.

Beauveria bassiana (Bb11): A Sustainable Solution for Eco-Friendly Pest Management

Beauveria bassiana (Bb11) is a naturally derived biopesticide developed to combat destructive pests such as the diamondback moth, fall armyworm, stem borers, thrips, and aphids. Sourced from a locally validated fungal isolate (Bb11), this bio-based solution offers governments and development programs a cost-effective, environmentally responsible alternative to synthetic pesticides. It supports food security goals by reducing yield losses while preserving beneficial insects and soil health.

To integrate Beauveria bassiana (Bb11) into your agricultural initiative, follow these steps:

Estimate Product Requirements
Determine required quantities based on target crops and pest pressure. For example:
   - Cabbage and leafy vegetables: Apply every 7–10 days during infestations.
   - Maize or pulses: Adjust frequency based on pest monitoring, vegetative stage of the plant and climatic conditions.
Assess Local Availability
Verify if Bb11-based products are registered and available in the country. If importing, review logistics, regulatory approvals, and estimated costs.
Train Extension Agents and Farmers
Provide hands-on training for proper application—typically as foliar sprays under moderate temperatures and medium to high humidity. Emphasize early-stage pest targeting and compatibility with integrated pest management (IPM) practices.
Disseminate Awareness Materials
Develop and distribute flyers, videos, and radio content to inform farmers and stakeholders about the safety, usage, and effectiveness of Bb11.
Promote Integrated Pest Management (IPM)
Encourage the combination of Bb11 with resistant crop varieties, crop rotation, and other IPM tools to strengthen pest control and reduce pesticide resistance.
Foster Institutional Partnerships
Collaborate with research institutes, local agrodealers, and extension services to scale adoption and ensure continuous technical support.

By adopting Beauveria bassiana (Bb11), your program can enhance pest resilience, protect biodiversity, and promote sustainable, climate-smart agriculture at scale.

Scaling Readiness describes how complete a technology's development is and its ability to be scaled. It produces a score that measures a technology's readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

Formulation: The biopesticide is typically available in powder or liquid form containing viable spores of Beauveria bassiana.
Application method:
- Foliar spray is the most common approach—apply directly to the crop foliage using a knapsack sprayer, ULV sprayer or motorized mist blower.
- Ensure even coverage, especially on the undersides of leaves where pests often hide.
Timing:
- Apply in the early morning or late afternoon to protect spores from UV light degradation.
- Best used at the early stages of pest infestation to maximize effectiveness.
Environmental conditions:
- High humidity (≥ 60%) and moderate temperatures (25–40°C) favor fungal germination and pest infection.
- Avoid applying during heavy rains or drought conditions.
Compatibility:
- Can be integrated with other IPM tools like pheromone traps, resistant varieties, and cultural practices.
- Avoid mixing with chemical fungicides, as they may reduce fungal viability.
- Compatible with pyrethroids, therefore mixable with pyrethroids.
Reapplication:
- Depending on infestation levels and environmental conditions, reapply every 7–10 days as needed.
