Herbicide Control of Sago Pondweed

Herbicide control is a great option for Sago Pondweed because you can literally apply the herbicide and then sit back and let it do its work. Most herbicides can control Sago Pondweed throughout the season and only needs to be applied once a year.

Herbicide Products To Control Sago Pondweed

Hydrothol 191 Granular Aquatic Weed Control-          Hydrothol 191 Granular

Hydrothol 191 Granular is highly effective at killing Sago Pondweed in the application area and not away from the targeted area. It’s active ingredient is Endothall, mono (N,N-dimethyl alkylamine) salt.

Hydrothol 191 Granular is a slow releasing herbicide which accounts for its long lasting effects. Studies show Hydrothol 191 Granular present in the lake bottom 3 months after its application and had no effect on aquatic life because of the slow release of active chemicals.


Aquathol Super K Granular Herbicide-          Aquathol Super K Granular 

Aquathol Super K is a granular herbicide that works especially well for early season Sago Pondweed. Its active ingredient is dipotassium salt of endothall and it prevents the weed from producing the proteins it needs.

Aquathol Super K begins working upon contact with Sago Pondweed and initial results can be seen in as little as 1 to 3 days. A full kill of the weed takes about 1 to 2 weeks.


Aquathol K Liquid Herbicide-          Aquathol K Liquid Herbicide

Aquathol K is a liquid herbicide that works well for early season Sago Pondweed, just like Aquathol Super K Granular. Its active ingredient is also dipotassium salt of endothall.

Aquathol K liquid herbicide works just as effectively as its counterpart Aquathol Super K, so it really boils down to whether you would rather use a liquid or a granular.
