Where must the golf course marker be placed after applying plant-regulating materials?

• A. It must be placed on tees 5 and 9
• B. It must be placed near the clubhouse
• C. It must be placed on the number-one and number-ten tees
• D. It must be placed on the practice range

Answer: (C)

After applying plant-regulating materials, the goal is to clearly mark where treated areas are so people know to avoid or take precautions during the restricted-entry interval. On an 18-hole golf course, the standard is to place the marker on the number-one tee and the number-ten tee, which mark the starting points for the front and back nine. This placement makes the notification visible to players as they begin each nine and communicates the treated zones across the course. Putting the marker at other locations wouldn’t reliably indicate the affected areas for all holes, such as near the clubhouse, on different tees, or at the practice range.
