Which factors influence potential environmental impact when applying near water?

• A. The pesticide color
• B. Proximity to water sources and droplet size
• C. The crop yield
• D. The brand name

Answer: (B)

When applying near water, how close you are to water sources and how large the spray droplets are mainly determine environmental impact. Being near streams, rivers, ponds, or groundwater increases the chances that pesticide moved during application or with runoff can reach the water and affect aquatic life or drinking-water supplies. Droplet size matters because fine droplets can drift with the air over longer distances and reach water bodies, while larger droplets tend to settle more quickly and stay closer to the target, reducing off-target movement. Other factors like pesticide color, crop yield, or brand name don’t influence these movement and fate processes.
