Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Sulfated fish oils as surfactants in pond

Not sure who to direct this question to, but are there any gotchas with using a sulfated fish oil surfactant in a pond?

TSC has a product Herbex, which is 100% fish oil, and it's primary use is for brush, etc. I use it for fence rows, and tried it today with Rodeo on American Lotus in an area that was muddy but void of water. It seemed to coat much better than other aquatic surfactants I have tried.

Since it is not labeled for aquatic use, I was reluctant to use it in standing water until I get an educated opinion.

Does it even matter since it isn't a herbicide?

I won't comment on Herbex, since I'm completely unfamiliar with this surfactant - but if it isn't labeled for aquatic-use, I'd avoid it for such sites.
MSO (methylated seed oil) surfactants are labeled and prescribed for many terrestrial and aquatic site treatments - depending on the accompanying herbicide. MSOs exhibit very good wetting and cuticle-infiltration characteristics - and probably have a much more agreeable aroma than fish-oil.

Thanks Kelly.

Corn syrup makes for a great surfactant and never a problem for anything.

Cheers Don.
