Eco-Farms Ltd. based out of Manitoba, Canada, offers a line of pesticide-free sunflower seeds.
They're now being made available to stores in the USA.
They come in two varieties, "Seasoned" and "Salted". I'm not sure what seasonings are in the Seasoned variety. Package text claims that they're grown using no chemical insecticide, herbicide, or fungicide sprays, and that they're exclusively grown on their own family farm.
They come in resealable 5.5 oz. stand-up bags. The suggested retail price is $1.49 each.
