Agricultural spray drones may be one of the most visible innovations in modern farming, but behind every flight lies a much larger story. In this edition of Field Notes from Green Farm 4 All, I reflect on my conversation with Sarah Hovinga of Bayer Crop Science and explore the science, research, and collaboration that support crop protection products before they ever reach a grower’s field. From pesticide labels to biologicals and regulatory science, this conversation is a reminder that meaningful innovation is built on evidence, not just technology.
