Going Viral: Virus-Based Biological Control Agents for Plant Protection

Area of Science:

• Agricultural Science
• Virology
• Ecology

Background:

• Fungi, oomycetes, insects, viruses, and bacteria cause significant economic losses in crop production.
• Chemical control is prevalent but faces challenges including resistance, environmental contamination, and ecosystem damage.
• Biological control agents (BCAs) are sought as safer alternatives, with viruses being underutilized due to regulatory and market barriers.

Purpose of the Study:

• To provide a comprehensive overview of virus-based biological control agents (BCAs) for managing agricultural pests and pathogens.
• To highlight novel approaches utilizing virus-host ecological interactions for biocontrol.
• To address the underuse of viruses as BCAs, particularly concerning regulatory and economic factors.

Main Methods:

• Comprehensive literature review on virus-based BCAs.
• Analysis of current state-of-the-art applications against fungi, bacteria, viruses, and insects.
• Exploration of new strategies focusing on indirect virus-host ecological interactions.

Main Results:

• Viruses are effective BCAs against a range of agricultural threats.
• New approaches extend beyond direct viral pathogenicity to include complex ecological interactions.
• Regulatory hurdles and market limitations hinder the widespread adoption of virus-based BCAs.

Conclusions:

• Virus-based biocontrol offers a promising, environmentally sound alternative to chemical pesticides.
• Innovative strategies focusing on ecological interactions can enhance the efficacy and applicability of viral BCAs.
• Addressing regulatory and economic challenges is crucial for realizing the full potential of virus-based biocontrol in sustainable agriculture.
