The efficiency of pesticide application in large treatment areas is significantly influenced by the method of herbicide dilution. Proper dilution is crucial because it ensures that the herbicide maintains its effectiveness while minimizing potential harm to non-target species and the surrounding environment. If the herbicide is diluted incorrectly—whether too concentrated or too weak—it may not effectively control the aquatic pests, leading to inadequate treatment and requiring additional applications, which can further increase costs and environmental impact.

While the type of pesticide used can impact effectiveness, it is the proper dilution of that herbicide that directly affects application success in extensive areas. Similarly, the applicator's skill level is important for executing the application correctly, but without proper dilution, even the most skilled applicator may struggle to achieve efficient results. The time of year may also play a role in pest management, as some herbicides are more effective during specific growth stages of plants or pests, but it is the method of dilution that primarily determines the immediate efficiency of the pesticide application itself.
