Biological Control of Plant Pathogens: A Global Perspective

Area of Science:

• Agricultural Science
• Microbiology
• Environmental Science

Background:

• Increasing global population necessitates enhanced agricultural output, leading to widespread chemical pesticide use.
• Concerns regarding the adverse health and environmental effects of chemical fungicides have spurred research into safer alternatives.
• Biological controls utilizing beneficial microorganisms have emerged as a promising strategy for crop disease management.

Purpose of the Study:

• To review the development process of biofungicide products from initial screening to market availability.
• To identify and discuss the challenges and obstacles hindering the successful development and commercialization of biofungicides.
• To highlight research gaps and factors affecting biofungicide efficacy and regulatory approval.

Main Methods:

• Comprehensive literature review of studies on biological control agents (BCAs) for crop protection.
• Analysis of the transition from laboratory screening of BCAs to the development of marketed biopesticide products.
• Examination of factors influencing the efficacy, market adoption, and regulatory pathways for biofungicides.

Main Results:

• Numerous BCAs, including species of *Bacillus*, *Pseudomonas*, and *Trichoderma*, have been identified and screened for biofungicidal activity.
• Despite extensive screening, a significant gap exists between the number of identified BCAs and the availability of commercialized biofungicide products.
• Challenges in product efficacy, formulation stability, and navigating complex regulatory procedures impede market entry.

Conclusions:

• The development of effective and commercially viable biofungicides requires addressing challenges in efficacy and regulatory frameworks.
• Further research and streamlined regulatory processes are crucial to bridge the gap between BCA discovery and market-ready biofungicide solutions.
• Sustainable agriculture relies on the successful implementation of biological control strategies to reduce reliance on chemical pesticides.
