This pathogen causes bacterial blight in rice and is a concern for global food security, causing up to 50% yield loss. This review provides a comprehensive analysis of Xoo, including its global distribution, disease cycle, and current management strategies, while critically evaluating the limitations of existing diagnostic methods. By focusing on Xoo, the paper addresses a gap in research that mostly focuses on the wider <i>Xanthomonas</i> genus. Emphasizing the role of Xoo in maintaining rice health, the review underscores the importance of detecting Xoo for successful disease management. Conventional approaches such as visual inspection, biochemical assays, and PCR-based techniques often lack the sensitivity, specificity, and scalability required for early and accurate detection, especially in resource-limited settings. To address these challenges, the review explores both current and emerging diagnostic technologies, including molecular, serological, and innovative field-deployable methods. Particular attention is given to advanced tools like biosensors, artificial intelligence, and IoT-enabled systems, which promise to enhance precision and efficiency in pathogen detection. By identifying research gaps and proposing actionable pathways, this work underscores the need for integrating traditional and modern diagnostic methods to achieve accessible, scalable, and effective solutions.

This approach has hindered effective comparisons of plant outcomes due to variations in plant type, growth duration, and soil characteristics. The current study addresses this gap by incorporating six separate milled biopolymers: pectin, starch, chitosan, polycaprolactone (PCL), polylactic acid (PLA), or polyhydroxybutyrate (PHB) into soil and directly comparing their impacts on tomato (<i>Solanum lycopersicum</i>) plants cultivated under identical environmental parameters. Plant outcomes were also studied when biopolymers were modified via the inclusion of two phosphorus (P) salts, forming two types of Polymer-P-containing salt composites with amorphous CaPO<sub>4</sub> (CaP) and CaHPO<sub>4</sub> (DCP). Our results revealed that chitosan-based treatments significantly improved tomato root and shoot biomass, with increases of 200–300% compared to the control plants. Chitosan-CaP and Chitosan-DCP also enhanced P uptake, though the effect was significantly more pronounced in the former, suggesting a synergy between chitosan and CaP. Neither Chitosan-P-containing salt treatment, however, mitigated P leaching from soil when compared to CaP or DCP applied in isolation. The two most hydrophilic biopolymers, pectin and starch, as well as their P-salt-containing counterparts, showed the most substantial reductions in biomass (∼80%) with respect to control plants, while similarly lowering P uptake and P retention in soil compared to CaP- and DCP-only plants. PCL- and PHB-based treatments also adversely influenced biomass and plant P, though these effects were not as drastic as those observed with pectin and starch. PLA-based soil amendments had no effect on any plant performance metric, though PLA-CaP, specifically, was the only treatment to appreciably mitigate P leaching (−63%). Based on these findings, subsequent tomato growth experiments were conducted over a longer 8-week period with CaP, DCP, Chitosan, Chitosan-CaP, and Chitosan-DCP. While all chitosan-treated plants showed similar enhancements in biomass, plants treated with Chitosan-CaP and Chitosan-DCP were the only ones to fruit, demonstrating the benefit of using chitosan in conjunction with a P source as compared to either treatment in isolation.
