While it is well established that water is a primary vector for bacterial movement between plants, few studies have examined the detailed hydrodynamic mechanisms involved, particularly in the context of leaf morphology, surface roughness, and microbial adhesion. This gap restricts our ability to develop predictive models and preventive strategies for managing rain-borne plant diseases. The project's general objective is to elucidate the coupling between raindrop impact dynamics and bacterial dispersal patterns on cherry leaves under realistic rainfall conditions. Specifically, it aims to (i) characterize the mechanical interaction between raindrops and cherry leaves using high-speed imaging and physical analysis to observe the dispersal patterns of Pseudomonas syringae pv. syringae (Pss). (ii) evaluate the spatial dispersal of Pss inoculated artificially onto cherry leaves at different concentrations under controlled temperature and rainfall conditions, and (iii) develop an integrative predictive model based on physical variables of rain-leaf interaction and experimentally measured environmental conditions to estimate the dispersal and severity of Pss attack. Methodologically, our study combines high-speed photography, controlled laboratory rain simulations, and microbiological assays. We will perform experiments in a custom-designed rainfall simulator allowing precise control of droplet size, velocity, and impact angle. Bacterial suspensions of Pseudomonas syringae—a pathogen commonly associated with cherry canker—will be applied to leaves under standardized conditions. The dynamics of droplet impact, splash formation, and secondary droplet ejection will be recorded at high temporal resolution to quantify mechanical energy transfer and spatial distribution of splashed particles. Parallel microbiological analyses will determine bacterial survival rates, concentration profiles, and the extent of leaf-to-leaf contamination. We will integrate these results into a predictive model linking rainfall characteristics to potential bacterial dispersal distances and infection probabilities. We aim to enhance our understanding of the biophysical coupling between rainfall and pathogen mobility, establish a set of empirical relationships for disease spread modeling, and provide practical recommendations for orchard management under varying climatic scenarios. By bridging the gap between plant pathology and fluid mechanics, this project will provide a mechanistic foundation for reducing rain-mediated bacterial diseases in high-value fruit crops, contributing to the sustainability and resilience of O'Higgins agriculture.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
