Hey farm gals, it’s Kara from Lange Girl Farms!
The big horses were out grazing this morning with their steady, grounded energy, while the alpacas moved along the fenceline checking everything out in their thoughtful way. I took time to hand-weed a few stubborn spots near the herbs and torch some young weeds before they could spread. The Siberian huskies had their own space to run, the llamas kept their quiet lookout, and the chickens and ducks were happily occupied in their secure run. These simple mornings without chemicals feel right — the land stays alive, the animals stay strong, and we have real peace of mind.
In Part 5 we followed the money and the Driscoll’s licensing model. Now in Part 6 we go back to the beginning: how flupyradifurone was discovered, developed into a commercial insecticide, and became a tool for strawberry and berry production. This history shows the same pattern we’ve seen across every series — a chemical is introduced as a “modern” solution, adoption spreads, and regenerative farms are left protecting their clean systems from the fallout.
Discovery: From Research to Commercial Insecticide
Flupyradifurone is a butenolide insecticide developed by Bayer Crop Science. It was created in the early 2000s as part of the search for new classes of insecticides that could target sucking pests (aphids, whiteflies, etc.) more selectively than older chemistries.
• Researchers at Bayer identified the molecule’s unique structure and its ability to act as a nicotinic acetylcholine receptor agonist, similar to neonicotinoids but from a different chemical family (butenolides).
• Extensive lab and field testing showed strong efficacy at low doses with claimed reduced risk to bees compared to some older insecticides.
• It was commercialized under brand names like Sivanto and quickly positioned as a tool for high-value crops like strawberries, berries, tree fruits, and vegetables where aphids and whiteflies cause significant damage.
The key innovation was its systemic movement: once absorbed by the plant, it spreads to new growth, providing longer-lasting protection without frequent re-applications.
Development and Adoption on Strawberries and Berries
Flupyradifurone was developed and marketed as a “bee-friendly” alternative to some neonicotinoids. Its main selling points were:
• Effective control of sucking pests that damage berries and reduce yields.
• Systemic activity that protects new growth during the long harvest window of strawberries.
• Use in both foliar sprays and soil applications.
Conventional strawberry growers adopted it rapidly because berries are delicate, prone to pest damage, and need consistent protection for long-distance shipping. It became part of standard spray programs, often used in rotation or combination with other insecticides and fungicides. As global berry demand grew, so did flupyradifurone use — especially on large-scale operations supplying major brands.
Like many systemic insecticides, its single-site mode of action means pests can develop resistance relatively quickly with repeated use, leading to higher rates or more mixtures over time.
Why This History Matters on Our Homestead
The story of flupyradifurone — from lab research to widespread use on conventional berries — shows how “modern” solutions for pest control often come with trade-offs. We refuse it entirely. We grow our own berries when possible, source from trusted local regenerative farms, or preserve what we harvest. We hand-weed, torch weeds, plant cover crops, and support beneficial insects because those methods build true balance instead of relying on systemic insecticides that can leave residues and harm pollinators.
Our alpacas and big horses graze clean pasture we’ve built without these chemicals. Our huskies, llamas, chickens, and ducks live without the added burden. The pattern is the same across every series: a chemical is introduced for convenience, resistance or new problems develop, and regenerative farms are left protecting their clean systems and choosing carefully what they buy or grow themselves.
Series Roadmap – What’s Coming Next (The Final Part!)
Part 7: Reclaiming our land – our exact holistic methods (hand-weeding, torch burning, mulch, cover crops, livestock grazing with our alpacas and big horses), Michigan-specific tips, and how we grow or source clean berries without these insecticides.
This deep history isn’t just background — it explains why so many of us have walked away from conventional berry production entirely. We can learn from the past and build something better.
Pin/save the entire series and comment below: Did the development as a “bee-friendly” alternative surprise you? How has this history shaped your choices on the homestead? I read every comment and appreciate your stories.
If you want to support a small regenerative farm that refuses these chemicals, check our shop for wildcrafted salves (perfect for hands after torching or weeding), herbal teas grown right here without sprays, or non-GMO seeds to start your own clean garden. Every purchase helps us keep protecting what matters.
We don’t have to carry forward this cycle. We can choose healthier soil, healthier animals, and healthier families—one deliberate, natural step at a time.
See you in the final Part 7, farm gals!
With love from the pasture,
