A site that would most likely require selective weed control is:

• A. Roadside turf
• B. Storage yards
• C. Substations
• D. Wooden bridges

Answer: (A)

Selective weed control is used when you want to remove unwanted plants while keeping the desired vegetation intact. Roadside turf fits this scenario perfectly because the goal is to maintain healthy turfgrass along roadsides while suppressing weeds that compete for nutrients and water. By using selective herbicides, you can target broadleaf or specific weed species without harming the grass you want to keep.

In contrast, storage yards, substations, and wooden bridges don’t have a valued stand of vegetation that needs to be preserved; these sites are typically managed to keep the area open or bare for access and safety, so nonselective or mechanical methods are more common.
