What type of agitation is sufficient for keeping wettable powders in suspension?

Hydraulic systems are particularly effective for keeping wettable powders in suspension due to their ability to generate a powerful flow of liquid. This type of agitation provides the necessary movement to ensure that the solid particles do not settle out of the solution. The high water flow rate created by hydraulic agitation effectively stirs the mixture, maintaining a uniform distribution of particles throughout the liquid. This is crucial when applying wettable powders, as uneven distribution can lead to ineffective pest control.

Mechanical systems, while they do provide agitation, may not always generate the same level of intensity needed for wettable powders compared to hydraulic systems. Piston pumps and centrifugal pumps can effectively transport liquids and may cause some agitation, but they don't typically maintain the necessary turbulence required for suspending wettable powders over prolonged periods. Therefore, hydraulic systems are the most suitable choice for ensuring that wettable powders remain evenly suspended in the solution during application.
