A pesticide transfer often begins with a small container, a concentrate bottle, and a worker trying to measure accurately beside a spray tank. The last few ounces can be awkward, especially if the bottle has a narrow opening or the cup is already wet from earlier use.
A poor grip or shallow rim makes the task harder for someone wearing chemical-resistant gloves.
Purpose-built pesticide measuring cups are designed around this routine job, with readable graduations, a shape that can be held steadily, and a lip that helps direct liquid into the tank opening.
