Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Bladderwort problem

People,

have a very small pond, 1/8th acre, kidney shaped. Only has gambuzia minnows, some crayfish, frogs, etc. It is 100% covered recently by bladderwort. I heard Diquat is an option, perhaps applying at only 1/4 of the surface at a time to prevent oxygen depletion for whatever life is in the pond. I think diquat id 2,4-d(?). If Im wrong, please advise.

BUT I heard 2,4-D is banned for sale in FL except for use in citrus. Is that true? If so, what other chemical compound can one use for bladderwort?

Thanks, people.
