Biosensor Technologies for Early Detection and Quantification of Plant Pathogens.

Area of Science:

• Agricultural science
• Biotechnology
• Plant pathology

Background:

• Plant pathogens significantly reduce crop yields, impacting food security.
• Conventional disease detection methods are often slow, inaccurate, and unsuitable for in-situ analysis.
• Over-reliance on chemical controls leads to resistance and environmental concerns.

Purpose of the Study:

• To review and compare traditional plant disease diagnostics with emerging biosensor technologies.
• To highlight the potential of nanoparticle-based biosensors for early and accurate plant pathogen detection.
• To discuss the challenges and opportunities of biosensors in informing plant disease management strategies.

Main Methods:

• Comparison of conventional culture-dependent, biochemical, and molecular methods.
• Focus on electrochemical and optical biosensors for plant pathogen detection.
• Review of nanoparticle-based biosensor applications.

Main Results:

• Conventional methods often lack the required accuracy, specificity, and rapidity for effective disease management.
• Biosensors, particularly electrochemical and optical types, show promise for sensitive and rapid in-situ detection.
• Nanoparticle-based biosensors offer a scalable approach for early plant disease diagnosis.

Conclusions:

• Biosensors represent a significant advancement over traditional methods for plant pathogen detection.
