An increasingly popular use for unmanned aerial systems (UAS) is drone applied site specific weed control (SSWC). Site-specific herbicide application allows applicators to target previously mapped weed clusters and spot sprays the targeted weeds individually. This benefits farmers by generating cost savings from reducing herbicide usage and limits overapplication of herbicide. This study aims to identify characteristics of spray drones that are desirable amongst farmers. A discrete choice experiment is used to identify attributes which farmers deem more valuable than others. This study finds that price, herbicide reduction rate, and application rate significantly impact a farmer’s decision to rent or purchase a spray drone for SSWC use.
