GAR: I would love to see that local co-op manager's face if an inspector for your state dept of agriculture walked into his store and asked for the person who was recommending diuron for aquatic treatments; or your farmer-friend's face for that matter.
I can assure you, their smug attitudes and winking smirks would disappear in a heartbeat.
I'm betting that the farmer would never contaminate his crop with a non-labeled pesticide: which begs the question, why would he do otherwise with his own pond - or encourage his neighbor to commit the same blunder. Evidently, he considers himself smarter than an impressive number of highly educated research chemists and environmental toxicologists.
To paraphrase an old Will Roger's quote: -That which we don't know rarely gets us into as much trouble as what we know, that simply ain't so.-
Bill: Interesting analogy, and quite accurate.
The farmer who recommended Karmex has since moved.
I no longer deal with the store I 1st purchased Karmex from. He never mentioned any law about using it in water even though I told him I would use it to kill algae in my pond. When I asked how to apply it he said to spread it "like you would feed chickens". I did; but unfortunately on a windy day. Some of the Karmex power blew onto the grass near the pond's edge & killed patches of grass where the Karnex power hit! I couldn't grow grass in those areas until I dug out & replaced the top soil.
I bought Duiron 80 from a different store the next year but didn't mention how I was going to use it until this year. That's when clerk immediately told me it was illegal to use in ponds. No problem, but it got me wondering why farmers could use it, etc & to post on this forum.
