I'll add one more thought to contemplate.
DuPont was the discoverer and original producer of diuron; back in the 60's I believe. Over the decades, DuPont pursued and received countless EPA registrations for diuron in a wide variety of terrestrial applications - and sold millions, possibly billions of pounds in the process. Yet, DuPont never, ever sought a diuron registration for aquatic use (a fact that most folks don't realize).
Now ask youself: Why would a large global company, with plenty of resources, decide to ignore an otherwise lucrative market-segment (aquatics, of any nature) for one of their flagship products?
Lackluster efficacy certainly wasn't an issue!
Let me know if anyone comes up with an answer that provides any sense of rationale or comfort for applying this product to your pond.
PS: Approximately 4 years ago, DuPont completely divested themselves from the global production and marketing of diuron (aka Karmex). Food for thought.....
