Rate-controller functions continue to evolve as different models and spraying systems are released onto the market. Spending time consulting the controller manual may alert the operator to functions they may not be aware the controller could perform.

Before operating any sprayer, the operator should check all controller inputs and settings for accuracy to ensure it can perform as intended.

A spray plan is a useful way to record all of the considerations the operator uses when selecting the spraying parameters, controller settings and the sprayer performance indicators.

Knowing what the flow rate (L/min) through the boom and the operating pressure should be at your typical spraying speeds will help to identify if the system is operating correctly.
