Air sampler improvements and ability of optical sensing to detect diseases

Through air sampling and optical sensing analysis, the amount and type of pathogens present can be determined. With reflectance measurements in the field, deviations from a healthy crop can be identified. Potentially large geographical regions and relatively small positions (<1 m²) in crop fields can be identified where special attention at specific moments is required. These spatial data will allow improving decision making algorithms and forecasting models. Accordingly, task 1 of the ‘Emerging Technologies’ activity of the PURE project aims at developing optical sensing and airborne inoculum sampling methods for macro scale mapping and monitoring of crops to identify unhealthy regions in cropped fields. This deliverable reports air sampler improvements and optical sensing pilot results at month 24 of the project.

The research leading to these results has received funding from the European Union Seventh Framework Programme (FP7/ 2007-2013) under the grant agreement n°265865- PURE
