In the course of some reporting for a freelance article, I stumbled across this list of pesticides that farmers can use and still be considered for the coveted "organic" label. Along with such common materials as "sodium fluoaluminate," which is apparently something mined in Greenland, organic farmers can keep the bugs away with:
- Boric acid
- "Codling moth granulosis virus"
- Insect extracts
- Pyrethrums (I believe these are based on a chemical found in chrysanthemums)
- Shells, ground (oyster, clam, lobster and crab)
- Tree seals
I'm assuming that "tree seals" don't actually live in trees...
