This Field Notes article accompanies my conversation with Sarah Hovinga, Regulatory Affairs Manager at Bayer Crop Science, on the Green Farm 4 All Podcast.

In our discussion, we explored crop protection, biologicals, agricultural spray drones, precision agriculture, and the science behind bringing new technologies to farmers.

One of the things I enjoy most about Green Farm 4 All is the opportunity to learn from the people shaping modern agriculture. Every conversation allows me to dive deeper into a topic, ask the questions that help me better understand it, and share that journey of discovery with others.

Agricultural spray drones are receiving tremendous attention today, and for good reason. They represent one of the fastest-growing technologies in modern farming. But as impressive as the aircraft themselves are, I have learned that understanding the future of agriculture requires looking beyond the equipment and learning from the people whose work makes these technologies possible.

That was exactly why I wanted to sit down with Sarah Hovinga, Regulatory Affairs Manager at Bayer Crop Science.

I’ve attended several of Sarah’s presentations over the years at agricultural conferences, and each time I came away realizing how much science, research, and regulatory work takes place long before a grower ever opens a jug of crop protection product or a drone lifts off from the edge of a field. I wanted to better understand that process, and more importantly, help others understand why it matters.

What followed was a fascinating conversation that reminded me that innovation in agriculture is rarely driven by a single technology. It is the result of researchers, manufacturers, universities, regulators, and growers all working toward the same goal: producing food safely, efficiently, and responsibly.

Drones Are Changing Agriculture—Research Helps Them Move Forward

One of the most interesting parts of our discussion centered on agricultural spray drones and the role science plays in helping new technologies become part of mainstream agriculture.

As spray drones continue to gain acceptance across the industry, researchers are generating the data needed to better understand how products perform when applied using this new application method. That information helps regulators evaluate applications and determine how pesticide labels can continue evolving alongside advances in technology.

Sarah explained that this work cannot be rushed. Spray drones operate differently from conventional application equipment, and those differences must be understood through careful scientific research. Every new study helps build the knowledge needed to support safe, effective, and responsible applications.

As someone who spends a great deal of time around agricultural drones, I found this perspective refreshing. We often celebrate the technology itself, but the real story is the research happening behind the scenes that allows innovation to move forward with confidence.

Twelve Years Before a Product Reaches the Farm

Perhaps the statistic that surprised me most during our conversation was the amount of time required to bring a new crop protection product to market.

Sarah explained that developing a new active ingredient can take approximately 12 years and require an investment of roughly $300 million before growers ever have access to the finished product.

Those numbers put modern crop protection into perspective.

Before a product ever reaches a field, it has already undergone years of laboratory research, greenhouse studies, field trials, environmental assessments, toxicology testing, and regulatory review. Every step is designed to answer an important question: can this product be used safely and effectively?

For me, this was one of the biggest takeaways from the interview. It’s easy to think only about the product in the container, but behind every label are years of scientific work performed by hundreds of researchers.

Biological Products Follow the Same Scientific Path

Another topic we explored was the growing interest in biological crop protection products.

With more biological solutions entering the marketplace, I was wondering whether these products follow a different regulatory process than conventional chemistries.

Sarah explained that while data requirements may vary by product, biologicals are still evaluated through a rigorous scientific process before reaching growers. Researchers spend years identifying promising candidates, studying their performance, and demonstrating that they are both safe and effective for their intended use.

That was an important reminder that innovation isn’t simply about discovering new technologies—it’s about generating the scientific evidence needed to support them.

Universities Continue to Build the Evidence

Another theme that stood out during our conversation was the important role universities play in advancing agriculture.

Independent researchers help answer many of the scientific questions that regulators and industry need before new technologies or application methods can be broadly adopted. Extension specialists then help translate that research into practical information growers can use in the field.

Whether the discussion involves biological products, spray drones, or emerging application technologies, collaboration among universities, industry, regulators, and growers remains one of agriculture’s greatest strengths.

Conversations Build Understanding

Toward the end of our discussion, we shifted from technology to public perception.

Agriculture is often discussed in headlines and social media, but the science behind many farming decisions is rarely explained in detail.

One of the reasons I enjoy producing the Green Farm 4 All podcast is because conversations like this allow us to slow down, ask questions, and hear directly from the people doing the work. Whether listeners ultimately agree or disagree on every topic isn’t the point. Understanding how decisions are made is.

The more we understand the science, the research, and the people behind our food system, the better equipped we are to have thoughtful conversations about agriculture’s future.

From My Field Notebook

When I first became interested in agricultural drones, I was fascinated by the aircraft themselves.

One thing this conversation reinforced for me—and one that I hope readers take away as well—is that it’s easy to be captivated by the technology. Spray drones may be one of the most visible advances in modern farming, but behind every flight lies an extraordinary network of science, research, regulation, and people working together to advance agriculture.

Farmers have always been practical innovators. They adopt new tools when those tools are proven to solve real problems safely, effectively, and economically. Building that confidence takes years of research, field trials, and collaboration among universities, manufacturers, regulators, and growers.

For me, that’s what Green Farm 4 All is all about.

Not simply showcasing technology, but helping people understand the people, the science, and the innovation that make modern agriculture possible.

If this conversation sparked your curiosity, I encourage you to listen to the full interview with Sarah Hovinga on the Green Farm 4 All Podcast. Whether you’re a grower, drone pilot, researcher, student, or simply someone who wants to better understand where your food comes from, I hope you’ll come away with the same appreciation I did: that every innovation in agriculture is built on a foundation of science.
