Which method is used on occasion but requires landing strips and is usually used near airports on flatter areas?

• A. Fixed wing aircraft
• B. Ground-based foliar and soil applications
• C. Hack and squirt applications
• D. Thinline and streamline applications

Answer: (A)

Fixed-wing aerial application is used when a large area needs to be treated quickly and ground access is impractical. Planes operate from landing strips, which is why this method is typically used near airports where such strips are available. The flatter, open terrain in these areas provides safer, more predictable flight paths for spraying, and the approach is selected when speed over wide areas outweighs the higher logistic and regulatory demands of aerial work. Ground-based foliar and soil applications are done from the ground; hack and squirt is a targeted tree-injection method; and thinline and streamline applications are narrow, line-focused methods usually not requiring aircraft.
