What is a potential issue with paddle agitation in spray tanks?

Paddle agitation in spray tanks can lead to foaming, which is a significant concern during pesticide applications. When paddles agitate the liquid in the tank, particularly if the formulation has surfactants or emulsifiers, it can introduce air into the mix. This air incorporation can create foam, which not only reduces the effective volume of the liquid and can alter the concentration of active ingredients but also complicates the spraying process. Excessive foaming can lead to difficulties in achieving an even application and may require additional management strategies to control.

While other issues such as inadequate mixing, excessive noise, and poor pressure regulation can occur under certain circumstances or with specific equipment configurations, foaming is a direct result of paddle agitation methods, making it a notable concern in pest management practices. Understanding this can help in choosing the right agitation method or adapting formulations to minimize foam production.
