This NebGuide discusses guidelines to quickly evaluate the performance of a sprayer. Sprayer calibration, nozzle discharge and speed checks are evaluated with minimal calculations. Tractor-mounted, pull-type, pick-up mounted and self-propelled pesticide application equipment are available from numerous sources. pesticide costs, potential crop damage, unsatisfactory control and environmental concerns make correct application important. Proper calibration to ensure accurate application must be a primary management consideration for both farmers and custom applicators. Application equipment users also should know proper application methods, chemical effects on equipment and correct cleaning and storage procedures of liquid sprayers.
