What condition typically arises when using high concentrations of polymer in spray systems?

Using high concentrations of polymer in spray systems often leads to decreased output from the sprayer. When polymers are added to a spray solution, they can significantly increase the viscosity of the liquid. This higher viscosity can affect how the liquid flows through the spraying equipment, making it more difficult for the pump and nozzles to deliver the intended volume at the desired pressure.

As a result, the overall efficiency of the spray system can diminish, leading to a lower output. In addition, the thicker solution may create blockages or reduce the effectiveness of the nozzle's atomization, which further impacts the amount and quality of the spray delivered to the target area.

Understanding this relationship between polymer concentration and sprayer performance is crucial for applicators to ensure effective pesticide delivery and to avoid unintended consequences in both application rates and coverage.
