If water is adjacent to the ROW treatment area or present within it, which factor should you consider?

• A. Wind speed
• B. Water adjacent to the treatment area or in the treatment area
• C. Sunlight exposure
• D. Soil type

Answer: (B)

When water is near or inside the ROW treatment area, protecting water quality becomes the priority. The factor to consider is the potential for pesticide movement into water through spray drift, surface runoff during rain, or leaching into groundwater. Because water bodies can be directly affected, you should check the label for required buffer zones, avoid applications when rain is likely or when runoff could occur, and choose practices and formulations that minimize movement toward water. Use drift-reducing nozzles and appropriate droplet sizes, maintain proper application timing, and follow any water-related restrictions on the label. While wind speed, sunlight exposure, and soil type can influence other aspects of pesticide behavior, the immediate concern here is preventing contamination of water by accounting for the water's proximity.
