Nonselective weed control sites include which of the following?

• A. Storage yards
• B. Substations
• C. Wooden bridges
• D. All of the above

Answer: (D)

Nonselective weed control is used in areas where you need to remove all vegetation, not just certain species, to maintain safety, access, and infrastructure. In storage yards, vegetation can interfere with equipment movement, storage operations, and visibility, so complete ground cover removal helps keep the area clear. In substations, clear zones around electrical equipment are essential for safety and reliability; any plant growth can create hazards or hinder maintenance, so a nonselective approach is appropriate. On wooden bridges, vegetation can trap moisture, accelerate wood decay, and obscure inspections or create slipping hazards, making total vegetation removal important. Because each of these sites requires eliminating all weed growth, they are all examples of nonselective weed control sites.
