RDE774 Assessment of alternative arable pesticide usage survey sampling strategies

The aim of this work is to explore different sampling methodologies for the Pesticide Usage Survey (PUS), and using power analysis attempt to understand how different experimental designs will alter the ability to detect changes in pesticide active substances over time. As a secondary aim, the work will also attempt to understand how changes to the PUS could affect the ability to detect changes and trends in the Pesticide Load Indicator metrics.
