I live in a culture that is surrounded by -cides: About all I can manage to do about it is to not intentionally poison myself... It really only took one decision... Once the decision was made then I didn't have to be wishy washy about it and say things like, "I don't use poisons, except for XYZ on the ABC plants, when they are infected by KLM bug That's a really bad bug!!!". My policy is to not use poisons ever regardless of the bug or disease, and regardless of whether the poison is natural or synthetic. I am thrilled as can be about how successful it has been for me. And how much money I save!!! Then I took it one step further and applied it to fertilizers... That saved me gobs of money... Then I applied it to seeds. I can grow my own, so I might as well. I still haven't learned how to grow onions since I stopped buying sets, but I'm making steady progress.
I don't try to wake anyone up, other that once in a while I say to someone, "I think that one of the first rules of healthy living is to not poison myself". I apply it to all kinds of cleaning products, and hygiene products, and paints, and foods, and medicines, and herbs, and vitamins, and pets, and air fresheners, and etc...
And I put up a sign on my fields. It has no legal or ethical standing, but it expresses my opinion.
