Which equipment is used for dispensing insecticidal soap or oil solutions with 2 to 4 gallon tanks and interchangeable nozzles?

• A. Sprayer
• B. Drop Spreader
• C. Manual Aerator
• D. Bow Saw

Answer: (A)

For applying liquid insecticides like soaps or horticultural oils, a sprayer is the appropriate tool. Sprayers are built to dispense liquid solutions and usually come with tanks in the 2 to 4 gallon range, which provides a good balance between capacity and portability for a treatment session. The interchangeable nozzles let you tailor the spray pattern and droplet size to achieve even coverage on leaves while controlling drift and runoff. The other options don’t fit: a drop spreader handles granular materials, not liquids; a manual aerator is used to introduce air into soil, not to apply liquids; a bow saw is a cutting tool for pruning. So a sprayer best fits the need.
