What should an applicator do when using a wettable powder in a backpack sprayer?

When using a wettable powder in a backpack sprayer, continually agitating the tank mix is essential for achieving an even distribution of the active ingredients throughout the solution. Wettable powders need to be thoroughly mixed with the liquid to ensure that the particles remain suspended and do not settle at the bottom of the tank.

If the mixture is allowed to settle or agitation is not maintained, the application may lead to inconsistent results, such as under-application of the pesticide, which could reduce its effectiveness. Conversely, if the sprayer is used without proper mixing, the applicator might get a concentrated dose of the powder in the initial spray followed by weaker applications as the agitation decreases. This inconsistency can lead to poor pest control and damage to the targeted plants or environment. Thus, maintaining agitation throughout the spraying process is crucial for effective application of wettable powders.
