Which agitation method utilizes paddles to mix the solution?

The method that utilizes paddles to mix the solution is mechanical agitation. This technique involves physically moving the liquid through the use of paddles, which can effectively mix the pesticide solution to ensure uniform distribution and maximize the effectiveness of the treatment. Mechanical agitation is commonly used in situations where a thorough blend of the solution is necessary before application.

In contrast to other methods, hydraulic agitation relies on the flow of liquid to create turbulence for mixing, which does not involve the use of paddles. Piston agitation refers to a form of mixing that uses a piston to create pressure, but it doesn't employ paddles either. Centrifugal agitation uses a spinning motion created by centrifugal force to mix solutions, also without the need for paddles. Understanding these distinctions helps to clarify why mechanical agitation is the correct answer for this specific agitation method.
