A device used to apply herbicide through a garden hose line is known as a:

• A. Water pressure applicator
• B. Weed wand
• C. Insecticide sprayer
• D. Fogger

Answer: (A)

The device relies on the water pressure from a garden hose to push herbicide through the line and out the spray head, giving you controlled, line-for-line coverage where you direct it. That direct use of hose pressure to deliver the herbicide is what makes it a water pressure applicator. A weed wand is just a spray nozzle for manual application and isn’t specifically tied to delivering herbicide through a hose line. An insecticide sprayer is meant for insecticides, not herbicides, and a fogger disperses a fine mist rather than delivering a controlled line-based spray. So the term that best matches the function is the device that uses the hose’s water pressure to apply herbicide through the line.
