> Many of the "organic" pesticides, copper sulfate, rotenone, and nicicotine sulfate

That's highly misleading:

1. Copper sulfate is required to be used such that copper accumulation is limited in the soil. [1]

2. Rotenone [2][3] and nicotine sulfate [3] are not allowed as USDA Organic pesticides.

Really, superkuh, for a user like you, your comment is embarrassing.
