What factors can affect pesticide performance in aquatic environments?

Water temperature and flow of water significantly influence pesticide performance in aquatic environments. Higher water temperatures can enhance the efficacy of certain pesticides by increasing their activity levels and reducing the time to achieve the desired effect on target organisms. Additionally, water flow dynamics can affect the distribution and dilution of the pesticide, impacting both its effectiveness and potential for non-target exposure.

In contrast, while sunlight may affect some aspects like photodegradation of certain pesticide formulations, it does not play as direct a role in performance as water temperature and flow. Water pressure is generally less relevant to pesticide efficacy. Wind speed and air humidity, relevant in terrestrial applications, have limited impact on substances used in water due to their aquatic nature. The type of vegetation and soil composition are more relevant to terrestrial pesticide applications and do not directly influence behavior in aquatic systems. Therefore, the key factors affecting pesticide use in aquatic environments are primarily related to the characteristics of the water itself.
