In the heart of Manila, Philippines, a groundbreaking study led by Toshiou Baba at the Center for Engineering and Sustainable Development Research, De La Salle University, is paving the way for advanced crop monitoring technologies. Published in *AgriEngineering* (which translates to *Agricultural Engineering*), the research delves into the world of chemiresistive and electrochemical sensing materials, aiming to detect volatile organic compounds (VOCs) emitted by potato and tomato plants under stress. This work could revolutionize how farmers and agritech companies approach disease detection and crop health management.
Tomatoes and potatoes, staple crops worldwide, are often plagued by diseases caused by pathogens like *Ralstonia* and *Fusarium*, leading to significant agricultural losses. Traditional methods of disease detection can be time-consuming and labor-intensive. Baba’s research offers a promising alternative: wearable plant sensors that can monitor VOCs as biomarkers of plant stress, enabling early detection of diseases.
The study reveals that different cultivars of potatoes and tomatoes emit unique VOC profiles when under stress, challenging the notion of universal biomarkers for specific diseases. “This variability underscores the complexity of plant-pathogen interactions and the need for tailored sensing solutions,” Baba explains. The research compares various sensing materials and mechanisms, highlighting the importance of sensitivity, selectivity, detection limits, response time, robustness, cost-effectiveness, and biocompatibility.
The findings suggest a future where biodegradable, wearable sensors made from flexible, biocompatible materials could become standard tools in precision agriculture. These sensors could monitor multiple parameters, possess self-healing properties, and even be designed using 3D printing technologies. Advanced nanomaterials and energy-harvesting technologies are also on the horizon, promising to make these sensors more efficient and sustainable.
Baba envisions a superstructure that bridges materials science, plant pathology, artificial intelligence, data science, and manufacturing. “By integrating these disciplines, we can develop sensors that are not only highly sensitive and flexible but also sustainable,” he says. This holistic approach could lead to significant advancements in agricultural monitoring, ultimately benefiting farmers and the broader agritech industry.
The commercial implications of this research are vast. For agritech companies, the development of wearable plant sensors could open new markets and create opportunities for innovative product offerings. For farmers, these technologies could mean more efficient and cost-effective ways to monitor crop health, leading to better yields and reduced losses.
As the agricultural sector continues to evolve, the integration of advanced sensing technologies will play a crucial role in shaping the future of farming. Baba’s research, published in *AgriEngineering*, is a significant step forward in this direction, offering insights and innovations that could transform the way we approach crop monitoring and disease management. The journey towards sustainable and precision agriculture is well underway, and the future looks promising.
