I understand that very smart people go through a lot of work to ensure the best results with the least risk.

One of the things I was interested in is the half-life of the chemicals and what happens to them over time. Also, What process is used now to qualify a chemical for certain uses.

Not trying to stir the pot, just thought more info might help all understand the process end to end and why the labels have limits.

Thanks for all the info. I am very thankful for knowledge.

What I would like to know in addition to what Brian asked...

It seems the active ingredients in approved and not approved herbicides for ponds can be the same. My impression is we can buy products with active ingredients like glyphosate or 2-4-D that are safe for ponds or not safe for ponds. It is the "other" ingredients that seem to be the issue. Pond approved products seem to cost more in my experience. Why do the "other" ingredients drive the price up? Why not use the same pond safe "other" ingredients in all the herbicides?
