Pond Boss Forums Thread Like Summary - Weed control with 2,4D

Have about 1 1/2 to 2 acre pond. need to control White water lily and water shield. Planning to use 2,4D.
Questions are:
Would Aquacide pellets be more effecient than liquid? Weeds are VERY thick in shallow areas.

Will 2,4 D harm some small, about 10' tall, cypress trees at edge of pond, couple are actually in the water.

Is there an "aquatic" form of 2,4 D, like there is for glyphosate?

Have read you should not use ester form of 2,4D, is this true? Should you only use "dichlorophenoxy acetic acid" form?

Thanks for any info.

OK, I'd go with that. I've used Navigate for years, primarily for patches of American Lotus, and never had any fish problems. I would say that being up wind and wearing proper PPE is needed because Navigate is extremely dusty when spreading.

Here is a link to an information page from a large supplier.

2,4-D Herbicides

Under the product information sheet, that link shows lots of products that are NOT applicable.

I believe their Navigate granules may be applicable to your situation.

White and yellow water lily and water shield are on that label as targets for that formulation.


*** I am definitely NOT an expert, and I have not used herbicides in my ponds at our property (but I use them frequently on our terrestrial undesirable plants).

There are many experts on Pond Boss that deploy herbicides on ponds as professionals, or have been treating their own ponds for many years. Hopefully, some will comment in your thread.
