What does bottom layer treatment refer to?

Bottom layer treatment refers to the application of pesticide that reaches the bottom of a pond. This method is crucial when dealing with aquatic pests that reside or grow close to the substrate or sediment at the bottom of water bodies.

Reaching the bottom ensures that the pesticide can effectively target organisms that may not be affected by treatments applied to the water surface or at mid-depth. This type of treatment is particularly important for controlling invasive plant species and other pests that thrive in the sediment layer, as these organisms can significantly alter aquatic ecosystems if not properly managed.

In contrast, treatments focused on the water surface or at the water's edge would not adequately address the issues posed by bottom-dwelling pests.
