text: Dave, take a lesson on toxicology.  If you can't talk RUPs and LD50, then you clearly don't understand the issue and what's wrong with it.  Birds are tiny and would be way more susceptible to these pesticides.  Have you seen masses of dead animals around farms?
  
  Nope.  Don't insult and beat around the bush.  You won't even find dead earthworms. If you apply an organic fungicide like copper sulfate at a high enough rate, you'd find dead soil but of course no one needs to know about that!
