What should you assess before applying pesticides near water sources?

Assessing the proximity of the water body and potential for runoff or drift is crucial before applying pesticides near water sources because it directly impacts both environmental safety and compliance with regulations. Pesticides can easily migrate from application sites to nearby water bodies through runoff, especially when there is rainfall or irrigation soon after application. Drift, which occurs when pesticides are carried away by wind during or after the application process, can also lead to contamination of aquatic environments.

Understanding this proximity helps in determining the appropriate buffer zones that should be maintained, selecting suitable application methods, and identifying weather conditions that may increase the risk of runoff or drift. Protecting water sources from pesticide contamination is not only important for maintaining ecosystem health but is also a legal requirement in many jurisdictions, including Kansas.
