What is one of the advantages of using granular formulations for aquatic herbicide treatments?

Using granular formulations for aquatic herbicide treatments offers several advantages, one of which is that they are confined to the bottom where submersed weeds are located. This targeting is particularly beneficial in aquatic environments, as many problematic aquatic plants, such as milfoil or water lily, tend to grow on or near the substrate. By applying a granular herbicide, the active ingredients can settle at the bottom, maximizing contact with the unwanted vegetation while minimizing the impact on the surrounding water column and non-target species.

This focused application also reduces the potential for herbicides to disperse through the water, which can lead to non-target effects and environmental concerns. Granular formulations generally release their active ingredients gradually, allowing for sustained action against the targeted weeds over time, thus enhancing the efficacy of the treatment. This makes granular options practical for managing specific aquatic weeds effectively.
