Which device is used for applying herbicide by hand-squeezing without a boom?

• A. Backpack sprayer
• B. Trigger pump
• C. Spot gun
• D. Wiping applicator

Answer: (B)

The main idea here is the handheld method that sprays herbicide without using a boom. A trigger pump fits this scenario best because it is a small, portable unit you squeeze by hand to pressurize the liquid and spray directly from a nozzle. This gives precise, controlled application on a small area without needing a boom or larger equipment.

A backpack sprayer, while handheld in use, is a larger unit worn on the back and usually involves a wand and nozzle; it’s not the simple hand-squeeze device described. A spot gun is a specialized nozzle used for targeted spraying but typically operates as part of a larger sprayer setup rather than as a standalone hand-squeeze device. A wiping applicator applies herbicide by wiping onto surfaces and doesn’t involve spraying.
