Hey farm gals, it’s Kara from Lange Girl Farms!
The big horses were 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.
We’ve covered many major herbicides, insecticides, fungicides, and growth regulators in previous series. Now we’re moving on to bifenazate, a common acaricide/insecticide found in conventional strawberries (including Driscoll’s) and many other berries, fruits, and vegetables. Independent testing has highlighted it among the multiple pesticides in Driscoll’s conventional strawberries, adding to concerns about childhood cancer clusters near heavy-spray areas. This series will follow the same 7-part deep-dive format.
In Part 1 we’re starting with the wake-up call: where bifenazate is used, its detection in strawberries and other foods, the health concerns, and why this hits regenerative homesteads like ours so hard. No sugar-coating — just the facts and why we say no.
The Current Reality: Heavy Use on Berries & Many Crops
Bifenazate is a carbazate acaricide primarily used to control mites (spider mites, two-spotted mites, etc.) but also effective against some other pests. It is commonly applied to:
• Strawberries (including Driscoll’s conventional varieties)
• Other berries (blueberries, raspberries, blackberries)
• Tree fruits, vegetables, and ornamentals
It is valued for its quick knockdown on mites and relatively long residual activity. In conventional strawberry production, mite pressure can be high in humid or greenhouse conditions, making bifenazate a go-to tool. In areas like Watsonville, California, heavy pesticide applications have been linked to elevated childhood cancer rates in nearby communities.
Health Concerns: Cancer Links & Broader Risks
Bifenazate is among the pesticides associated with childhood cancer risk when sprayed near homes. Key concerns include:
• Potential neurotoxicity and developmental effects.
• Contribution to the cumulative pesticide load, especially when combined with the other chemicals found in conventional strawberries.
• Impacts on beneficial insects and the broader ecosystem.
In Watsonville and similar strawberry-growing regions, schools sit just yards from spray zones, with pesticides lingering in the air for hours after application. Driscoll’s licenses genetics to growers but does not apply the chemicals themselves, complicating direct accountability.
Why This Hits Regenerative Homesteads Like Ours
Even if we grow our own, drift, runoff, and contaminated water from conventional operations can reach our land. Buying conventional strawberries or berries means supporting a system that uses these chemicals near homes and schools. Our alpacas and big horses graze clean pasture we’ve built without these burdens. Our huskies, llamas, chickens, and ducks live without the added chemical load.
We hand-weed, torch weeds, and grow or source as much as possible ourselves because we refuse to participate in or be exposed to this cycle.
Series Roadmap – What’s Coming Next
Part 2: Bifenazate 101 – the chemistry, how it works as a mite control agent, and why it’s used on strawberries and other crops.
Part 3: The devastating toll on humans (cancer and developmental links), livestock, wildlife, and waterways.
Part 4: On our plates – residues in strawberries, berries, and other foods, plus the cumulative load.
Part 5: Follow the money – manufacturers, the Driscoll’s licensing model, and regulatory status.
Part 6: The roots – discovery and development as an acaricide/insecticide.
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 series is for every homestead gal tired of finding out their “healthy” fruit is laced with concerning chemicals. We don’t have to accept it.
Pin/save the series and comment below: Have you stopped buying conventional strawberries or berries after seeing reports like this? Are you growing your own or sourcing from trusted farms? I read every comment.
If you want to support a farm refusing these chemicals entirely, swing by the shop for our wildcrafted salves (great after hand-weeding or torch work), herbal teas grown right here without sprays, or non-GMO seeds for your own regenerative garden. Every purchase helps us keep protecting our land and animals.
We can protect our kids, our animals, and our future—one holistic choice at a time.
See you in Part 2, farm gals!
With love from the pasture,
