Herbicide Products To Control Watermilfoil

Navigate Granular Aquatic Herbicide-          Navigate Granular

Navigate Granular is formulated on special heat treated attaclay granules that resist rapid decomposition in water. They quickly sink to your lake or pond bottom and release 2,4-D into the critical root zone.

Initial effects are indicated by brittle stems and curling leaf tips and are noticeable within 7 to 10 days. A full kill will occur within 3 to 5 weeks.


Hydrothol 191 Granular Aquatic Weed Control-          Hydrothol 191 Granular

Hydrothol 191 Granular is highly effective at killing Watermilfoil 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.
