Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Are my trees safe?

The short version:

Will herbacides harm the willow and poplar trees going at the edge of my pond???

The long version:

I am expecting that even with aeration, my 20+ year neglected pond is going to need aquatic herbacide to curb the submergent vegetation (coontail and others) and cat tails that take it over by mid summer.

I plan to use Sanco Industries Cat Plex for the Cat Tails and WeedPlex Pro for the submergent vegetation. My concern is that I have a large will and several poplar trees that grow at the edge of the water -- I'm guessing their roots are kept wet by the pond. Will the herbacides hurt the trees?

FYI...I'm using the Sanco products because they are available locally.

The CattPlex is glyphosate, so as long as you keep overspray under control the trees should be safe.

I don't know about the other one, it has been replaced by Tsunami DQ according to their website. It's diquat based. You can to to http://www.sancoind.com/products/Herbicides and read the label.

What are the active ingredients ?

Tsunami DQ and Weedplex Pro have the active ingredient listed as: "37.3% diquat dibromide"
