Which factor is important to consider regarding tree roots when planning ROW herbicide application?

• A. Be aware of tree roots that might be in treatment area
• B. Be aware of weather forecast
• C. Be aware of wind direction
• D. Be aware of tree leaves

Answer: (A)

Tree roots extend beyond the trunk into the surrounding soil, and herbicides in the treatment area can reach those roots or move through the soil to injure them. If active roots are in the planned spray zone, the tree can suffer root damage or decline even if the trunk isn’t directly sprayed. That’s why identifying and avoiding root zones in ROW planning is the most important factor. Weather, wind direction, and leaves matter for drift and coverage, but they don’t address the direct risk to the tree’s root system in the treatment area.
