Hydrothol® Granular should be spread evenly throughout treatment area when plants are present. Most effective when applied on a calm day. When applying Hydrothol® Granular aquatic herbicide, we recommend using a broadcasting spreader.
Hydrothol® provides control where you need it,in the application area, not away from the target area. For this reason, Hydrothol® is a valuable tool in improving access to the water for recreational activities such as swimming, fishing and water skiing. Hydrothol® is effective in muddy or murky water because it does not bind to the suspended sediment or organic matter. Hydrothol® is also an effective algaecide.
