Bottom treatments are not recommended if a body of water has which type of water or bottoms?

Bottom treatments are not recommended for flowing, muddy bodies of water because of the complex interactions between the water movement, sediment type, and the effectiveness of the treatment methods. In such environments, the water's flow can disperse the treatment material quickly, making it difficult to achieve the desired concentration needed for effective pest management. The muddy substrate can also trap sediments and reduce the efficacy of the treatment, as the active ingredients may not reach the target species effectively.

In contrast, calm sandy, stagnant rocky, or clean clear waters may allow treatments to settle more effectively and provide better contact with aquatic pests, leading to more successful management outcomes.
