Abstract

Plant pathogens, including bacteria, fungi, nematodes, oomycetes, and viruses, are a major threat to global agricultural production and food security. The timely detection and monitoring of plant pathogens is critical for effective disease management. Technological advances in sensors and microfluidics have enabled new diagnostic tools for field-based detection and quantification of pathogens. In this article, we provide a comprehensive review of recent developments in sensor and microfluidic technologies that are being integrated into plant pathology and disease management. We discuss various classes of sensors used for plant pathogen diagnostics, including optical, electrochemical, and piezoelectric sensors. We also focus on microfluidic devices known as lab-on-a-chip systems that offer portability, multiplexing, and automation for plant disease diagnostics. Insights are provided into innovative strategies for disease monitoring and control through precise spatial-temporal targeting guided by sensors and microfluidics. The major opportunities and remaining challenges in further integrating these technologies into precision agriculture are also considered. Overall, this review highlights the key role of sensors and microfluidics in accelerating progress against plant pathogens through more precise, rapid, and affordable diagnostics at the point-of-care.
