Remote access methods and systems for plant pathogen (e.g., fungi or fungus-like organisms) assessment and management, and uses thereof, in particular for real-time agricultural applications, are described herein. In embodiments, the method and systems combine the capture of pathogenic spores (e.g., by impaction on an adhesive surface), laboratory analysis to identify the spores (e.g., by microscopy and/or PGR), collecting weather data, determining the level of risk for each pathogen, and providing an output to a user, who may for example access such risk data remotely as a risk report. A weather station is installed in proximity to the field/area where the spore sampling/collection occurs, and allows the constant transfer of weather data to effect the risk assessment. The risk assessment may be used to direct and optimize pesticide (e.g., fungicide) application in accordance with the pathogen identification and assessed risk level.
