Abstract: Long gone are the days of scribbling swath characterization calculations on paper and second guessing the accuracy of applications. This presentation will review the new easy-to-use swath characterization cloud application freely available on the Valent BioSciences webpage. Accurate swath characterization is essential for optimizing product efficacy, cost, and helps ensure applications are within label requirements. This user-friendly interactive app can be used for granular larvicides and allows applicators to conduct aerial swath analysis by simply uploading a single document. After uploading the appropriate data into the app, a downloadable report is generated visualizing both predicted and actual swath. Users can adjust swath width and application rate to visualize how these metrics in real time affect the swath characterization of the uploaded data. An overview of how to conduct aerial granular swath characterization analysis using the cloud-based app will be provided along with information on how to access the free tool.
