Both of you make valid points, and I am trying to use IPM (Integrated Pest Management) practices.
Once again I am not an expert and don't pretend to be.
I'll back up smallaxe's statement about Big Ag with this comparison.
It's the private property residential applicator in Los Angeles county that puts more runoff pesticide and fertilizer into their water table with OTC purchases of P & F than all of Agriculture in California combined! Think about it, the No. 1 crop in California is cotton, then rice produced on a world scale. That's scary.
BTW, Check out this page on TGLC http://www.syix.com/emu/html/tg3.html
That site is red flagged by my security software for syware, you might be more careful when you provide links.
