What method is used to create a bottom treatment?

The method utilized to create a bottom treatment involves using weighted brass pipes connected to a hose. This technique allows for precise application of aquatic pesticides directly onto the bottom of a water body, targeting specific areas where unwanted vegetation or pests may be prevalent. The weighted pipes ensure that the pesticide sinks to the appropriate depth, allowing effective treatment of the intended area while minimizing the impact on the water column and surrounding ecosystem.

Dropping pellets from a plane generally refers to aerial applications for broader coverage, which might not achieve the localized treatment required for bottom applications. Spraying from the water's surface is more suited for treating water column pests and does not effectively reach or control bottom-dwelling organisms. Hand broadcasting herbicide along the shoreline is typically used for vegetation control at the water's edge and does not adequately address issues below the surface. Thus, the use of weighted brass pipes delivers the most effective targeted treatment in bottom applications.
